Of parvenus, priests and prophets: An exploration of transformations of (some) economists and their subject
Authors: Winzler Tim
Published: October 2024

Bridget Fowler’s work develops the topic of social transformation in Bourdieu’s writing – how it comes about, how it is to be framed theoretically, and who the agents of that change may be. This article continues this important line of thought by looking at one group that (sometimes) does contribute to social transformation. I call this group parvenus: ascendants from lower positions that move into leading positions within various fields. I take the field of science as a specific example. Building on research investigating the motivations of German economics students, I explore, and reflect upon, a distinct characteristic of the parvenu’s habitus: i.e. a tension introduced by exposure to different cultural milieus and influences. The close analysis suggests a more variable definition of the term parvenu, as well as novel ways of social reproduction.

Published: October 2024

To solve the problems of poor real-time tension tracking, large overshoot, long adjustment time, and large tension fluctuation error that exist in the current control system for yarn feeding in the circular weft knitting machine, this paper presents an optimized and improved adaptive genetic algorithm (AGA) for adjusting the PID (Proportional Integral Derivative) parameters of the tension control part of the yarn-conveying system (AGA-PID). The algorithm is combined with the field-oriented control technology of the permanent magnet synchronous motor to design a closed-loop control strategy for the yarn-conveying system of a circular weft knitting machine. The MATLAB-Simulink simulation model was used to analyze the external tension loop-based AGA-PID controller and permanent magnet synchronous motor dual closed-loop control strategy of the yarn transport control system. The experimental verification was conducted by constructing an experimental platform that simulates the real process of yarn transportation. The outcomes of system simulations and experiments have consistently demonstrated that the AGA-PID control algorithm outperforms the GA-PID and PID control algorithms in terms of overshooting, response speed, stability, and anti-jamming ability. The yarn transport control system, which is designed to operate based on an AGA-PID control algorithm, is capable of reducing the fluctuations in tension that occur during the transportation of yarn and exhibits enhanced control accuracy, effectively stabilizing yarn tension control during the conveying process. The application of this algorithm can enhance the overall elasticity uniformity and surface flatness of knitted fabrics, thereby facilitating the realization of adjustable and controllable local elasticity in fabrics.

This study aims to examine how the subcomponents and overall measurement of ecological footprint, as well as the use of information and communication technologies, affect health expenditures. For this study, the sample group consisted of the top 25 countries with the highest ecological footprint for the period 2000 to 2021. System GMM estimation results demonstrate that economic growth and ecological footprint have a positive impact on health expenditures. Covid-19 dummy variables, have a statistically significant and positive effect on health expenditures. On the other hand, information and communication technologies has a statistically significant but negative effect on health expenditures. The estimation results show that the Covid-19 pandemic increased health expenditures. Looking at the effect of subcomponents of environmental degradation on health expenditures, all subcomponents have a statistically significant and positive effect on health expenditures. It is seen that the most effective variable is forest products. The variable that has almost the same impact as the footprint of forest products is the carbon footprint. Carbon footprint has significant and positive impact on health expenditures, followed by fishing grounds cropland, grazing land, built-up land. The results of the study indicate which forms of pollution should be given priority by policymakers in order to prevent an increase in health expenditure resulting from environmental degradation.

Authors: Agarwal Vrinda , Upadhyay Jaya , Sahu Nency , Parihar Rashmi , Agarwal Pawan , Sharma Dhananjaya
Published: October 2024

This descriptive survey assessed knowledge, attitude and practice regarding analgesic prescription practices in neonates. A web-based questionnaire was developed and circulated to 150 physicians working in public and private neonatal intensive care units, of whom 87% were aware of neonatal pain perception; however, only 57.3% had any definite pain management policy. Some 66% were aware of a pain assessment tool in neonates, yet none had used it, though 80% used analgesics in their neonatal intensive care unit but only 44.3% were satisfied with the subsequent pain management. The most commonly used agents were midazolam and fentanyl. A total of 55% thought that opioid analgesia should not be used in neonates and morphine was used by only 5%; however, there seemed a general acceptance of opioid use since 86% used fentanyl as an analgesic. Non-pharmacological methods were used by 81%. Pain treatment in neonatal intensive care units is thus suboptimal and requires more attention.

Time-resolved three-dimensional ultrasound (3D + t US) is a promising imaging modality for monitoring abdominal aortic aneurysms (AAAs), providing their 3D geometry and motion. The lateral contrast of US is poor, a well-documented drawback which multi-perspective (MP) imaging could resolve. This study aims to show the feasibility of in vivo multi-perspective 3D + t ultrasound imaging of AAAs for improving the image contrast and displacement accuracy. To achieve this, single-perspective (SP) aortic ultrasound images from three different angles were spatiotemporally registered and fused, and the displacements were compounded. The fused MP had a significantly higher wall-lumen contrast than the SP images, for both patients and volunteers ( P < .001). MP radial displacements patterns are smoother than SP patterns in 67% of volunteers and 92% of patients. The MP images from three angles have a decreased tracking error ( P < .001 for all participants), and an improved SNRe compared to two out of three SP images ( P < .05). This study has shown the added value of MP 3D + t US, improving both image contrast and displacement accuracy in AAA imaging. This is a step toward using multiple or large transducers in the clinic to capture the 3D geometry and strain more accurately, for patient-specific characterization of AAAs.
A portrait of self-regulated musical learning behaviors among rock musicians: Applications in music education
Authors: Holmes-Davis Tina
Published: October 2024

Rock music and Western classical music seem very different but musicians in the two cultures may have enough self-regulated musical learning behaviors in common for concurrent application in school-based music education. In this paper, I describe the self-reported self-regulated musical learning behaviors of seven successful rock musicians, compare their behaviors to those expected in the Western classical tradition, and suggest ways to combine norms from both traditions in effective music education programs. Data are collected through digital ethnography methodology from a series of interviews published in YouTube. Emergent themes in the self-regulated musical learning behaviors of rock musicians include (1) passion for music making, (2) the importance of choice, (3) a need for personal control over learning, and (4) an emphasis on musical composition in daily practice.
Confidants for life: Examining sibling relationship positivity and disclosure in U.S. Latinx college students while considering the role of familism

Published: October 2024

Familism is a central facet of Latin culture, yet there has been little work examining its role within the sibling relationship. Importantly, young adulthood provides a unique context where sibling dynamics may shift as independence increases and one begins to solidify their personal beliefs. During this time, sibling relationship quality remains influential. One mechanism to encourage positive sibling relationships is by teasing apart disclosure content. Therefore, we posited the following research questions: Is disclosure content associated with sibling relationship quality? Are there differential associations between familism dimensions (referent, support, obligations, and respect for family) and sibling relationship quality? Do these familism dimensions moderate the association between domain-differentiated disclosure and sibling relationship quality? To address these questions, via online surveys, 186 Latinx undergraduates ( M age = 21.35, SD = 1.79) reported on frequency of disclosure to their closest-in-age sibling, sibling relationship quality, and endorsement of four familism values. Findings revealed that more frequent engagement in personal disclosure (e.g., “How I spend my free time”) was associated with more reports of sibling positivity. With prudential disclosure (e.g., “Whether I smoke cigarettes”), more frequent disclosure was associated with less sibling positivity. All four dimensions of familism were associated with more sibling positivity. For personal disclosure, across all familism models, its association with sibling positivity was magnified under average to high levels of familism endorsement. For prudential disclosure, its association with sibling relationship quality was magnified under high levels of familism endorsement for all models except for respect for family. Within the respect for family model, when endorsed at low levels, multifaceted (e.g., “Whether I stay out late”) disclosure was associated with more sibling positivity. Our study highlights the particularly positive implications of siblings disclosing about personal domain issues compared to other topical domains. Our work also suggests familism is positive for sibling relationships, but interestingly, when it interacts with disclosure, the findings are mixed.
Exploring the impact of cyber and traditional crime victimization: Impact comparisons and explanatory factors
Authors: Borwell Jildau , Jansen Jurjen , Stol Wouter
Published: October 2024

As cybercrime victimization rates continue to rise, our understanding of their impact, especially compared to traditional crime, remains limited. To address this knowledge gap, we conducted surveys among 910 crime victims, measuring the impact of cyber and traditional variants of property, person-centered, and sexual crime. We compared the impact of: (1) residential burglary and hacking of online bank accounts; (2) doorstep deception and bank helpdesk fraud; (3) in-person threats and online threats; and (4) sexual assault and image-based sexual abuse. Impact was categorized into peritraumatic stress, internalizing problems, externalizing problems, financial impact, and damaged self-image. Our findings reveal that cybercrime impact mostly equals or exceeds that of traditional crimes. Disparities especially emerge in terms of higher peritraumatic stress experienced by victims of cyber property crime, and more damage to self-image suffered by victims of both cyber property and cyber sexual crimes. Furthermore, we identified significant determinants of victim impact among crime characteristics, and social, personal, and demographic factors, some varying between cyber and traditional crime. Our study emphasizes the implications of the technological nature of cybercrime and the relatively active role played by cybercrime victims, while also considering the issue of victim blaming. Furthermore, we underscore the need for targeted victim support and prioritization of cybercrime.
Estimating Change in Health-Related Quality of Life before and after Stroke: Challenges and Possible Solutions
Authors: Thompson Nicolas R. , Lapin Brittany R. , Katzan Irene L.
Published: October 2024

Background

Estimating change in health-related quality of life (HRQOL) from pre- to poststroke is challenging because HRQOL is rarely collected prior to stroke. Leveraging HRQOL data collected both before and after stroke, we sought to estimate the change in HRQOL from prestroke to early poststroke.

Methods

Stroke survivors completed the Patient-Reported Outcomes Measurement Information System Global Health (PROMIS-GH) scale at both pre- and early poststroke. Patient characteristics were compared for those who did and did not complete the PROMIS-GH. The mean change in PROMIS-GH T-score was estimated using complete case analysis, multiple imputation, and multiple imputation with delta adjustment.

Results

A total of 4,473 stroke survivors were included (mean age 63.1 ± 14.1 y, 47.5% female, 82.6% ischemic stroke). A total of 993 (22.2%) patients completed the PROMIS-GH at prestroke while 2,298 (51.4%) completed it early poststroke. Compared with those without PROMIS-GH, patients with PROMIS-GH prestroke had worse comorbidity burden. Patients who completed PROMIS-GH early poststroke had better early poststroke clinician-rated function and shorter hospital length of stay. Complete case analysis and multiple imputation revealed patients’ PROMIS-GH T-scores worsened by 2 to 3 points. Multiple imputation with delta adjustment revealed patients’ PROMIS-GH T-scores worsened by 4 to 10 points, depending on delta values chosen.

Conclusions

Systematic differences in patients who completed the PROMIS-GH at both pre- and early poststroke suggest that missing PROMIS-GH scores may be missing not at random (MNAR). Multiple imputation with delta adjustment, which is better suited for MNAR data, may be a preferable method for analysis of change in HRQOL from pre- to poststroke. Given our study’s large proportion of missing HRQOL data, future studies with less missing HRQOL data are necessary to verify our results.

Highlights

Estimating the change in health-related quality of life from pre- to poststroke is challenging because health-related quality-of-life data are rarely collected prior to stroke. Previously used methods to assess the burden of stroke on health-related quality of life suffer from recall bias and selection bias. Using health-related quality-of-life data collected both before and after stroke, we sought to estimate the change in health-related quality of life after stroke using statistical methods that account for missing data. Comparisons of patients who did and did not complete health-related quality-of-life scales at both pre- and poststroke suggested that missing data may be missing not at random. Statistical methods that account for data that are missing not at random revealed more worsening in health-related quality of life after stroke than traditional methods such as complete case analysis or multiple imputation.
Time-optimal ergodic search: Multiscale coverage in minimum time
Authors: Dong Dayi Ethan , Berger Henry , Abraham Ian
Published: October 2024

Search and exploration capabilities are essential for robots to inspect hazardous areas, support scientific expeditions in extreme environments, and potentially save human lives in natural disasters. The variability of scale in these problems requires robots to reason about time alongside their dynamics and sensor capabilities to effectively assess and explore for information. Recent advances in ergodic search methods have shown promise in supporting trajectory planning for exploration in continuous, multiscale environments with dynamics consideration. However, these methods are still limited by their inability to effectively reason about and adapt the time to explore in response to their environment. This ability is crucial for adapting exploration to variable-resolution information-gathering tasks. To address this limitation, this paper poses the time-optimal ergodic search problem and investigates solutions for fast, multiscale, and adaptive robotic exploration trajectories. The problem is formulated as a minimum-time problem with an ergodic inequality constraint whose upper bound specifies the amount of coverage needed. We show the existence of optimal solutions using Pontryagin’s conditions of optimality, and we demonstrate effective, minimum-time coverage numerically through a direct transcription optimization approach. The efficacy of the approach in generating time-optimal search trajectories is demonstrated in simulation under several nonlinear dynamic constraints, and in a physical experiment using a drone in a cluttered environment. We find that constraints such as obstacle avoidance are readily integrated into our formulation, and we show through an ablation study the flexibility of search capabilities at various scales. Last, we contribute a receding-horizon formulation of time-optimal ergodic search for sensor-driven information-gathering and demonstrate improved adaptive sampling capabilities in localization tasks.
Impact of microRNAs on cardiovascular diseases and aging
Authors: Sheikh Md Sayed Ali , Salma Umme
Published: October 2024

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality for both men and women among all ethnicities worldwide. Although significant improvements in the management of CVD occurred in the 20th century, non-invasive, universal, early diagnostic biomarkers and newer therapeutic drugs are needed for clinical treatment by physicians. MicroRNAs (miRNAs) are a class of endogenous, non-coding, single-stranded, small RNA molecules that are critically controlled by all human biological processes. Moreover, dysregulated miRNA expression is directly involved in various CVDs, including stable coronary artery disease and acute coronary syndrome. Several miRNAs that are enriched in the plasma of CVD patients have potential as clinical biomarkers, and overexpression or inhibition of specific miRNAs has novel therapeutic significance in the management of CVD. Aging is a multifactorial physiological process that gradually deteriorates tissue and organ function and is considered a non-modifiable major risk factor for CVDs. Recently, several studies established that various miRNAs essentially regulate aging and aging-related disease processes. This narrative review briefly discusses the recently updated molecular involvement of miRNAs in CVDs, their possible diagnostic, prognostic, and therapeutic value, and their relationship to the aging process.

Published: October 2024

The effects of rare earth Ce on purifying molten steel, modifying inclusions and micro-alloying in 430 ferritic stainless-steel bearings with Sn and Cu has been studied in this paper. The results demonstrate that Ce can purify molten steel, modify inclusions, enhance the mechanical properties and improve the pitting and corrosion resistance of the experimental steel. Ce effectively purifies the molten steel, reducing the total oxygen (T. O) content to as low as 0.00086 wt.% and sulphur (S) content to 0.0020 wt.%. The transformation of inclusions in the steel follows the sequence of MnS·Al2O3 → CeAlO3 → Ce2O2S → Ce2O3 with increasing Ce content. The number of inclusions initially decreases and then increases, with the experimental steel containing 0.012 wt.% Ce showing the best cleaning effect. Additionally, Ce treatment only slightly improves the mechanical properties of the experimental steel, but significantly enhances its pitting corrosion resistance and intergranular corrosion resistance by changing the enrichment state of carbides and impurity elements at the grain boundaries. In detail, Ce can partially inhibit the precipitation of M23C6 type carbides at grain boundaries, thereby improving the intergranular corrosion resistance of the experimental steel.
The Self and the Other: Individual Emotions and Ontological Security in Turkish Foreign Policy
Authors: Sofuoğlu Nasuh , Sharani Samer , Ermihan Erman
Published: October 2024

Emotions and ontological security open up one of the latest avenues in International Relations (IR). An increasing number of interdisciplinary approaches have been engaging in emotions and ontological security, for example, foreign policy analysis. However, academic research is scarce concerning the triangulation of emotions, foreign policy, and individual ontological security. Driven by the gap in the literature, the study analyzes how Turkey’s foreign policy decisions influence individual existentialism in terms of ontological security during the AKP era. A subsidiary question addresses how Turkey’s foreign policy decisions adjust/affect individual emotions towards its most engaged and interacted countries. Based on Ontological Security Theory (OST), the study has conducted 20 interviews. The questions cover Turkey’s foreign policy milestones: the start of the EU accession negotiations, the “one minute incident,” the Mavi Marmara incident, and the Arab Uprisings and the Syrian Civil War. The questions aim to reveal people’s emotional reactions to and descriptions of such events. The interview transcripts are analyzed in a Critical Discourse Analysis (CDA) context. Through CDA, the individuals’ perceptions of risk, threat, and danger are analyzed to seek the determinants of growing existential uncertainty in tandem with significant foreign policy decisions of the AKP government. This study finds that foreign policy decisions in Turkey impact individuals’ emotions based on key events. Through the case of Turkey, the study contributes to the emerging literature on emotions and ontological security by studying the dimensions between foreign policy and individual insecurities and emotions.
Design of Two-Layer Roller Compacted Concrete with Joints by KENSLAB
Authors: Mohammed Haneen , Hacham Zainab , Thom Nick , Dawson Andrew
Published: October 2024

Roller compacted concrete (RCC) is a type of rigid pavement that is designed in a similar way to conventional concrete pavements reflecting its mode of failure. The thickness design of RCC pavements is based on keeping the flexural stresses and fatigue damage in the pavement caused by wheel loads within allowable limits. As in all jointed concrete pavements, there is a greater effect from loads placed along edges and less at interior locations in the pavement. Joints in RCC pavement are clearly critical areas and form weak points. RCC is typically constructed with saw-cut joints to prevent random cracking, improve the appearance of the pavement surface, and maintain the highest possible load transfer across the joints. This paper presents an approach to designing the thickness of a two-layer RCC with induced cracks (i.e., joints) based on load transfer stiffness and fatigue damage, using the KENSLAB program to obtain pavement life, predict joint deterioration, and pavement damage.

Published: October 2024

Warning signs are often deployed at bridge overpasses during winter to warn motorists of potentially icy surface conditions on the bridge, although the effectiveness of these signs is questionable. One potential improvement to the standard signage methods is the bridge deck warning system (BDWS), which activates a flashing warning sign border or beacon when conditions warrant based on real-time weather and bridge surface data. However, BDWSs have not been broadly implemented in the United States, and consequently, their effectiveness as a safety countermeasure is not well established. To address this knowledge gap, a series of winter field evaluations were performed along three freeway bridge overpasses in Michigan to assess the effectiveness of various BDWS strategies as a speed reduction countermeasure for motorists approaching a potentially icy bridge. The results showed that a BDWS with a flashing light emitting diode (LED) border reduced motorist speeds when encountering a bridge during winter weather conditions compared with the standard “Bridge Ices Before Road” warning sign. The speed reduction effect was consistent between passenger cars and heavy trucks, but was somewhat stronger at night compared with daytime. Greater speed reductions were observed when the BDWS sign was combined with a dynamic speed feedback sign (DSFS) that displayed a “Slow Down” or “Icy Road” message to approaching motorists, with the strongest effects observed when the DSFS message was pulsed between high and low brightness intensities. BDWSs that included only a flashing overhead beacon did not have a significant effect on speeds compared with the standard warning sign.
Mast Cells Mediate Acute Inflammatory Responses After Glenoid Labral Tears and Can Be Inhibited With Cromolyn in a Rat Model
Authors: Co Cynthia M. , Vaish Bhavya , Hoang Le Q. , Nguyen Tam , Borrelli Joseph , Millett Peter J. , Tang Liping
Published: October 2024

Background:

Injuries to the glenoid labrum have been recognized as a source of joint pain and discomfort, which may be associated with the inflammatory responses that lead to the deterioration of labral tissue. However, it is unclear whether the torn labrum prompts mast cell (MC) activation, resulting in synovial inflammatory responses that lead to labral tissue degeneration.

Purpose:

To determine the potential influence of activated MC on synovial inflammatory responses and subsequent labral tissue degeneration and shoulder function deterioration in a rat model by monitoring MC behavior and sequential inflammatory responses within the synovial tissue and labral tissue after injury, suture repair, and MC stabilizer administration.

Study Design:

Controlled laboratory study.

Methods:

Anteroinferior glenoid labral tears were generated in the right shoulder of rats (n = 20) and repaired using a tunneled suture technique. Synovial tissue inflammatory responses were modulated in some rats with intraperitoneal administration of an MC stabilizer—cromolyn (n = 10). At weeks 1 and 3, MC activation, synovial inflammatory responses, and labral degeneration were histologically evaluated. Simultaneously, gait analysis was performed before and after surgical repair to assess the worsening of the shoulder function after the injury and treatment.

Results:

Resident MC degranulation after labral injury (50.48% ± 8.23% activated at week 1) contributed to the initiation of synovial tissue inflammatory cell recruitment, inflammatory product release, matrix metalloproteinase-13, and subsequent labral tissue extracellular matrix degeneration. The administration of cromolyn, an MC stabilizer, was found to significantly diminish injury-mediated inflammatory responses (inflammatory cell infiltration and subsequent proinflammatory product secretion) and improve shoulder functional recovery.

Conclusion:

MC activation is responsible for labral tear–associated synovial inflammation and labral degeneration. The administration of cromolyn can significantly diminish the cascade of inflammatory reactions after labral injury.

Clinical Relevance:

Our findings support the concept that MC stabilizers may be used as a complementary therapeutic option in the treatment and repair of labral tears.
Anterior Slope–Modifying Osteotomies Alter the Length Change Behavior of the Superficial Medial Collateral Ligament: A Biomechanical Study
Authors: Peez Christian , Ottens Carla , Deichsel Adrian , Raschke Michael J. , Briese Thorben , Herbst Elmar , Robinson James R. , Kittl Christoph
Published: October 2024

Background:

Increased tibial slope has been shown to lead to higher rates of anterior cruciate ligament graft failure. A slope-decreasing osteotomy can reduce in situ anterior cruciate ligament force and may mitigate this risk. However, how this procedure may affect the length change behavior of the medial ligamentous structures is unknown.

Purpose/Hypothesis:

The purpose of this study was to examine the effect of anterior slope–modifying osteotomies on the medial ligamentous structures. It was hypothesized that (1) decreasing the tibial slope would lead to shortening of the superficial medial collateral ligament (sMCL), (2) while the fibers of the posterior oblique ligament (POL) would be unaffected.

Study Design:

Descriptive laboratory study.

Methods:

Eight fresh-frozen cadaveric knee specimens underwent anatomic dissection to precisely identify the medial ligamentous structures. The knees were mounted in a custom-made kinematics rig with the quadriceps muscle and iliotibial tract loaded. An anterior slope–modifying osteotomy was performed and fixed using an external fixator, which allowed modification of the wedge height between −15 and +10 mm in 5-mm increments. Threads were mounted between pins positioned at the anterior, middle, and posterior parts of the tibial and femoral attachments of the sMCL and POL. For different tibial slope modifications, length changes between the tibiofemoral pin combinations were recorded using a rotary encoder as the knee was flexed between 0° and 120°.

Results:

All sMCL fiber regions shortened with slope reduction ( P < .001) and lengthened with slope increase ( P < .001), with the anterior sMCL fibers more affected than the posterior sMCL fibers. A 15-mm anterior closing-wedge high tibial osteotomy (ACWHTO) resulted in a 6.9% ± 3.0% decrease in the length of the anterior sMCL fibers compared with a 3.6% ± 2.3% decrease for the posterior sMCL fibers. A 10-mm anterior opening-wedge high tibial osteotomy (AOWHTO) increased anterior sMCL fiber length by 5.9% ± 2.3% and posterior sMCL fiber length by 1.6% ± 1.0%. The POL fibers were not significantly affected by a slope-modifying osteotomy.

Conclusion:

Tibial slope–modifying osteotomies changed the length change pattern of the sMCL such that an AOWHTO increased whereas an ACWHTO decreased the sMCL strain. This effect was most pronounced for the anterior fibers of the sMCL. The length change pattern of the POL remained unaffected by slope-modifying osteotomy.

Clinical Relevance:

Surgeons should be aware that anterior tibial slope–modifying osteotomies affect the biomechanics of the sMCL. After an extensive ACWHTO, patients may develop a medial or anteromedial instability, while an AOWHTO may overconstrain the medial compartment.
Factors Associated With Health-Related Quality of Life Among Community-Dwelling Older Adults Without Social Participation in Japan: A Cross-Sectional Study
Authors: Mutai Hitoshi , Obuchi Kohei , Yokoi Katsushi , Furukawa Tomomi
Published: October 2024

This study aimed to identify the characteristics of community-dwelling older adults who exhibited high health-related quality of life (HRQOL) without social participation. This cross-sectional observational study collected data using a mailed questionnaire. This study included 1,183 community-dwelling older adults aged ≥65 years who lived in Japan. HRQOL was assessed via the EuroQol 5-Dimensions 5-Levels (EQ-5D-5L). Multivariate analysis was performed; full health status (EQ-5D-5L = 1) was used as the objective variable, and socio-demographic, lifestyle, and health-related variables were used as the explanatory variables. Driving (OR = 3.846), economic situation (1.938), purpose in life (2.211), primary illness (0.398), low physical function (0.051), and depressive symptoms (0.288) were associated with higher HRQOL among community-dwelling older adults without social participation. This exploratory study suggests the possibility of promoting and improving the HRQOL of community-dwelling older adults without social participation by strengthening specific factors among them.
An MFA–LCA framework for goal-oriented waste management studies: ‘Zero Waste to Landfill’ strategies for institutions
Authors: Maçin Kadriye Elif , Arıkan Osman Atilla , Damgaard Anders
Published: October 2024

Institutions such as university communities can be considered miniature versions of the larger society in which they exist. Nonetheless even though it should be easier to manage waste at an institution, their waste management (WM) programmes are typically lack an overall goal for improving environmental impact and are not optimally structured or operated. In part this is due to a lack of a framework that promotes a goal-oriented WM strategy. For instance, zero waste (ZW) to landfill studies have gained prominence in recent years, but generally there is a lack of clear guidance on how to carry out ZW strategies effectively at either, municipal or institutional levels. To fill this gap, this study aims to provide a framework that enables institutions to develop a goal-oriented WM strategy applying the principles of material flow analysis and life cycle assessment. The framework assumes that no prior data are available, and a study will therefore begin by collecting primary data followed by secondary data. The case study is presented in this article, along with the introduction of the framework, using ZW management scenarios in the Istanbul Technical University Ayazağa Campus. The results of the case study show that, it is not possible to achieve ZW to landfill on university campuses. And simply diverting waste from landfill (min 74% to max ~100%) does not necessarily lead to circularity (min 20% to max ~66%) or directly address public attitudes towards ZW goals.
Studying Understudied Populations’ Travel Behaviors with a Machine Learning Approach: A Focus on Hispanic and Latinx Households
Authors: Tian Guang , Danton Bob
Published: October 2024

To address a gap in the literature regarding differential effects of built environments (BE) on minority populations, this study uses boosted regression tree modeling to explore travel behaviors of Hispanic and Latinx (H/L) households, finding significant differences in the variables that influenced these households compared to others. Overall, BE variables had greater impacts on H/L households than others. Nonlinear effects (effective ranges, thresholds) were identified for top-ranking BE contributors: transit stop density, activity density, land use mix, and destination accessibility. Compact development is shown to have increased impacts on reducing vehicle miles traveled (VMT) for these populations.

Published: October 2024

A Patient Navigation (PN) model of care was introduced in a large metropolitan hospital in Ontario (Canada) to support transitions in care for older adults in 2019. The patient navigator is a community social worker or “community transitional lead” embedded in the hospital’s in care teams to assist with discharge planning and provide follow-up care to older adults, their families, and/or care partners for up to 90 days. Initially, the PN program supported acute care patients and has since expanded in the Emergency Department and Reactivation Care Centre. In this cohort retrospective observational study, we described the new PN model of care by analyzing the clinical notes collected by the patient navigator. This article provides preliminary insights for health leaders who are interested in implementing this novel PN model to improve transitions of care in a hospital setting.

When a Battered Victim Kills Their Abuser: The Impact of Child and Expert Testimony on Mock Jurors’ Decision-Making
Authors: Chae Hana , McWilliams Kelly
Published: October 2024

The present study investigated the effects of child and expert witness testimony on mock jurors’ decision-making and perceptions of a case in which a female defendant claimed self-defense as the reason for killing her husband during a domestic dispute. A 3 (expert witness: Battered Woman Syndrome [BWS] vs. Social Agency [SA] vs. No Expert) × 3 (child witness: Age 5 vs. Age 8 vs. no child) between-subject design was used to examine the effects of two different forms of expert testimony and their interaction with the presence of a child witness. Jury-eligible participants ( N = 370) were recruited from Amazon Mechanical Turk and a Psychology Undergraduate Student Pool. The mock jurors who were exposed to the BWS expert perceived the defendant as more guilty when an 8-year-old testified compared to when no child testified at all. Furthermore, when the jurors were exposed to the BWS expert, they imposed a harsher sentence on the defendant when an 8-year-old child testified compared to a 5-year-old child or no child testifying. Although the jurors perceived the defendant in the BWS condition as more fearful compared to no expert and the SA condition, this knowledge did not seem to translate into a lighter verdict or sentencing decision. This study aims to provide guidelines for future researchers and legal professionals considering the issue of expert testimony and child witnesses in intimate partner homicides.

Published: October 2024

Workplace sexual harassment represents a critical risk to contemporary organizations, with evidence indicating that its prevalence is increasing. Research has consistently demonstrated that workplace-sexual-harassment victimization exerts negative impacts on employees’ health and wellbeing. However, no empirical studies have examined how these impacts vary by lesbian, gay, bisexual, trans, and queer (LGBTQ+) status. In this study, we leverage a unique survey dataset (2022 Australian Workplace Equality Index Employee Survey, n = 44,943) and random-intercept, multilevel regression models to estimate the relationships between workplace-sexual-harassment victimization and employee wellbeing. Expanding on earlier studies, we consider how these relationships vary between LGBTQ+ and other employees, across domains of employee wellbeing, and with the timing of sexual harassment. Our results reveal large, negative, and statistically significant impacts of sexual harassment on employee wellbeing. The impacts are comparatively larger for LGBTQ+ employees and recent harassment experiences, and manifest across all domains of employee wellbeing. These findings underscore the urgent need for holistic programs to combat workplace sexual harassment, and the importance of connecting these programs with diversity and inclusion initiatives.

The purpose of this investigation is to document the prevalence and consequences of technology-facilitated abuse (TFA) among college students and examine whether gender identity and sexual identity are associated with TFA exposure and related academic and mental health consequences. Data were analyzed from a campus climate survey distributed in Spring 2022. Data from 1,543 college students were collected for TFA experiences, academic consequences, and TFA-related depression, anxiety, and traumatic stress. Multiple linear regression analyses were conducted to test for unique contributions of sexual identity, gender identity, and number of TFA experiences to the outcomes of academic consequences, depression, anxiety, and traumatic stress. The number of TFA experiences was a significant predictor across all models. The contributions of sexual identity and gender identity differed for each outcome. The results of this study align with prior research which has found sexual identity and gender identity to affect outcomes associated with TFA. In addition, TFA was more prevalent among sexual and gender minority students, and the consequences of TFA were more severe within this population. These results suggest that programming takes a dual approach in addressing TFA through reducing TFA exposure and mitigating the impacts of TFA on mental health and other outcomes.
Facilitating Health-Promoting Self-Care in Older Adults: A Theory Synthesis
Authors: Sabo Kathryn , Hunter Revell Susan
Published: October 2024

The authors describe the development of a model that focuses on how primary care providers can facilitate health promotion in older adults. The health-promoting self-care in older adults (HPSOA) model was developed through a synthesis of key concepts from the Health Promotion model and the Modeling Role Modeling Theory. Walker and Avant’s strategy for theory synthesis was used in its development. The model prioritizes rapport building to foster a trusting patient-provider relationship and focuses on long-term solutions to health promotion. Further model use through testing, research, and application in practice is recommended.

Gazacide: Palestinians From Refugeehood to Ontological Obliteration
Authors: Nijim Mohammed
Published: October 2024

This article addresses the ongoing genocide in Gaza and argues that it must be understood in a larger historical context of settler colonialism. While Israel has always sought the completion of its settler-colonial project, I argue that the current genocide seeks immediate results of dispossession and annexation. My study examines the plight of refugees and contends that the right of return is at the center of Palestinians’ struggle. Return, land, and resistance are three key elements of the Palestinian identity that should be stressed in genocide studies. I argue that Israel’s approach before 7th October constituted slow-motion genocide and after that date its approach marked an accelerated form of genocide. I employ the new term Gazacide to encompass Israel’s approach in Gaza since the 1948 Nakba. To gain a deeper understanding of genocide and the destruction inflicted upon Gazans as a social group, I employ figurational sociology. I conclude with a discussion on culpability and intent and argue that all levels of the Israeli bureaucratic system as well as individuals must be held accountable.
Is it time for a European Convention against Racial Profiling?
Authors: de Vries Karin
Published: October 2024

Four years after the murder of George Floyd and the global Black Lives Matter protests, racial profiling not only remains prevalent in law enforcement practices in- and outside Europe, but takes on new forms in the wake of technological developments enabling large scale data analysis and the use of algorithmic risk profiles. A few years ago, the European Court of Human Rights (ECtHR) first dealt explicitly with the issue of racial profiling in the twin cases of Basu v. Germany and Muhammad v. Switzerland. More recently, the ECtHR held in Wa Baile c. Suisse that Switzerland had violated the prohibition of discrimination by subjecting the applicant to racial profiling at Zürich train station, as part of a police action to apprehend persons without a valid residence permit. 1 While these judgments, especially in Wa Baile, go some way towards securing international State accountability for racial profiling, they also illustrate the difficulties of fighting such profiling as a form of structural discrimination under the ECHR. Meanwhile other human rights bodies, at the European and international levels, have both acknowledged the structural nature of racial profiling and published numerous policy guidelines and recommendations for positive State action to ensure non-discriminatory law enforcement. Yet, to date all of these instruments remain at the level of soft law. Despite the ECtHR's recent efforts, European human rights law thus does not impose legal obligations on States to actively prevent and combat racial profiling. This column signals this gap, and considers some of the pros and cons of adopting a European Convention against Racial Profiling.
Numerical modeling and analysis of multistage gear transmission system in wind turbine gearbox under load uncertainty

A multistage gear transmission system (MGTS) is widely used in wind turbine gearboxes. Its dynamic responses are closely related to stochastic aerodynamic torque that has a wide interval range between cut-in and cut-out wind speeds. However, most of the dynamic models of MGTS lack attention to dynamic responses caused by uncertainties of multiple parameters under varied input torque. In this study, a dynamic modeling method in conjunction with interval uncertain analysis of MGTS caused by multiple load-related parameters due to varied input torques is proposed. A comprehensive dynamic model of MGTS is developed considering time-varying gear mesh transmission error, load-related gear mesh stiffness and bearing stiffness as well as flexible shafts. The reasonability of simulation is validated, and then the effects of multiple load-related parameters on uncertain dynamic responses are discussed in-depth. Results show that both gear mesh stiffness and bearing stiffness are enlarged with increasing input torque to cause uncertain dynamic responses. These uncertainties would propagate along the flexible shaft and be suppressed by system rigidity. The dominant transverse vibration modes of shafts are sensitive to bearing stiffness, thus, uncertain bearing stiffness has remarkable effects on dynamic responses than gear mesh stiffness.
