Examining Mindfulness’s Mediating Role in the Relationship Between Infidelity Tendency and Divorce Anxiety
Authors: Kahraman Süleyman , Özbay Ahmet
Published: January 2025

This study explores the role of mindfulness in marriage as a potential mediator in the relationship between infidelity tendencies and divorce anxiety among married individuals. Employing a sample of 415 married individuals, the research utilized a correlational model to examine the predictive capacity of marital mindfulness. The assessment involved the Mindfulness in Marriage Scale, Infidelity Tendency Scale, and Divorce Anxiety Scale, supplemented by a demographic information form. We analyzed the data using SPSS, incorporating techniques such as Pearson correlation and mediation analysis for parametric distributions. The analysis identified a statistically significant, low, negative correlation between infidelity tendency and divorce anxiety. Additionally, there was a significant, low-positive correlation between infidelity tendency and marital mindfulness. The relationship between divorce anxiety and marital mindfulness also displayed a significant, low negative correlation. Furthermore, the study determined that marital mindfulness plays a significant role as a partial mediator in the relationship between infidelity tendency and divorce anxiety. The findings emphasize the importance of incorporating mindfulness practices in marital counseling and interventions aimed at reducing divorce anxiety and managing infidelity tendencies. We discuss the limitations and implications for future studies to improve our understanding and application of mindfulness in marital contexts.
A Meta-analysis of the Prevalence of Food Insecurity Among People Experiencing Housing Insecurity and Homelessness in the United States
Authors: Jackson Carolyn L. , Hart Cody A. , Uribe-Lacy C. Jeff , Yang Phillip , Tsai Jack
Published: January 2025

Objectives:

Studies suggest that people experiencing housing insecurity and homelessness (HIH) have varying experiences with food insecurity. We estimated the prevalence of food insecurity and identified the factors associated with it among people experiencing HIH in the United States.

Methods:

We conducted a meta-analysis of the prevalence of food insecurity among people experiencing HIH and a systematic review of associated factors through a comprehensive search of 8 academic databases. We identified 3398 unique articles and included 40 studies in the review that met the following criteria: included observational or experimental data on the prevalence of food insecurity among people experiencing HIH, conducted in the United States, and written in English.

Results:

The overall prevalence of food insecurity was 57% (95% CI, 48%-65%). Most people experiencing HIH had food insecurity, and our estimated prevalence among people experiencing HIH was >4 times higher than the prevalence in the US population. Experiencing symptoms of a mental health condition (eg, depression, posttraumatic stress disorder, anxiety) in addition to HIH was most frequently (7 datasets) associated with increased odds of food insecurity. Social and institutional support was most frequently (5 datasets) associated with decreased odds of food insecurity.

Conclusion:

Our findings suggest that multisector coordination is needed to address individual- and system-level factors associated with food insecurity and HIH.
Expanding the ‘Third Space’ between Western and non-Western knowledge: Nakane Chie’s Japanese Society as anti-Eurocentric theory
Authors: Ushiyama Rin
Published: January 2025

Decolonial theorists have frequently employed dichotomies such as North–South, East–West, White–Black and Metropole–Periphery to characterise the exclusion of knowledge produced by marginalised populations around the world. This article argues that such dichotomies overlook a body of knowledge that lies in the liminal space between these polarities: the Third Space of ideas. It proposes that a more diverse history of sociological thought requires an acknowledgement of thinkers who developed putatively ‘Western’ ideas towards anti-Eurocentrism. Through a case study of the Japanese anthropologist Nakane Chie and her 1970 book Japanese Society, this article shows how concepts of ‘hybridity’ and ‘contamination’ are essential for reconstructing how so-called ‘non-Western’ scholars innovated Western theories in anti-Eurocentric directions. This article shows how the sociological canon could be expanded through an attention to how different schools of thought have evolved transnationally.
Simulation of fiber arrangement in slivers based on image processing
Authors: Zhu Guoqing , Wang Xiao , Liu Meina , Gao Xiaoyan , Liu Yanhui , Sun Na
Published: January 2025

The fiber arrangement in a sliver has a significant effect on sliver quality, especially on its evenness. In this work, a novel method was developed to simulate fiber arrangement based on the variation fineness of each sliver subsegment relative to the mean sliver fineness, which was acquired from the tested sliver unevenness curve by image processing. The modeling results of viscose indicated that the non-random fiber arrangement in the sliver could be appropriately and graphically expressed by the variation in the fineness of each sliver subsection relative to the mean sliver fineness. The results further indicated that the simulated fiber arrangements in the sliver were in line with actual ones. Moreover, the relative errors between the irregularities calculated from the fiber arrangement in the sliver and those measured were less than 8%, whereas the relative errors between the simulated values from the random fiber arrangement and those tested were approximately 95%. The obtained simulation results demonstrated that this new method accurately simulated the non-random fiber arrangement in the sliver and provided an accurate prediction of sliver irregularity in the further post-spinning processes.
Spiraling Up: Agency and Resilience among Indigenous Communities during the COVID-19 Pandemic
Authors: Watts Michelle , Drexler Kristin , Kimsey Bridget , Caole Anthony
Published: January 2025

Based on 140 interviews with respondents in six Indigenous communities in Alaska, New Mexico, Belize, and Guatemala, this phenomenological study focuses on Indigenous communities during the COVID-19 pandemic. Using Flora and Flora’s Community Capitals Framework, as well as Emery and Flora’s concept of the spiral of Community Capitals assets, this article explores both the challenges and coping mechanisms of Indigenous Peoples. Our findings suggest that perceived well-being during the pandemic was influenced by perceptions of agency as well as sentiment regarding pandemic policies. An initial “spiraling down” of community assets was offset by community strengths, particularly socio-cultural assets, leading to a “spiraling up.” This article seeks to highlight the voices of Indigenous Peoples, demonstrating through lived experiences how our respondents used the strengths of their community to reverse the downward spiral of assets during the pandemic, while serving as a contribution to the literature on governance and cultural protection.
Autistic Applicants’ Job Interview Experiences and Accommodation Preferences: An Intersectional Analysis
Authors: Ezerins Maira E. , Simon Lauren S. , Rosen Christopher C.
Published: January 2025

Although more organizations are seeking autistic applicants, autistic people remain in an unemployment crisis. This may be due in part to job interviews, which often implicitly evaluate relational and social skills—an area with which many autistic people struggle. To determine how to better support autistic applicants, we conduct a mixed methods study to identify, from their own perspective, the accommodations that would have the greatest impact on autistic individuals’ interview anxiety and performance. Additionally, we examine differences in interview anxiety and preferred adjustments to the interview process between both autistic and allistic participants and intersectionally across gender. Findings revealed additive effects of neurotype and gender on interview anxiety, with autistic participants reporting higher anxiety than allistic participants, and women reporting higher anxiety than men. Interestingly, despite a small number of notable differences, there were far more similarities between groups regarding preferred interview adjustments. These findings suggest that many adjustments to the interview process may be helpful across neurotypes, although they are perhaps particularly beneficial for alleviating the comparatively higher anxiety levels experienced by autistic applicants. Overall, there is a need to consider how and whether current interview best practices (e.g., standardization and structure) can be adapted to facilitate the inclusion of diverse neurotypes across a range of individual differences. As a starting point, we offer practical guidelines for managers wishing to improve the interview process for autistic and allistic applicants alike and set a foundation for future research.
Study on a Strategy to Improve the Image Quality and Imaging Depth for Novel Synthetic Aperture Schemes: An Experimental Investigation
Authors: Seetharaman Aadavan , Thittai Arun K.
Published: January 2025

Imaging depth remains a restriction for Synthetic Aperture (SA) approaches, even though SA techniques have been shown to overcome some of the drawbacks of Conventional Focused Beamforming (CFB) technique. This limitation is attributed to lesser energy per transmit in SA techniques compared to that of CFB technique. Therefore, in this paper, a systematic investigation is done to evaluate the improvement in imaging depth and image quality of B-mode ultrasound images in the case of SA technique using PZT transducer by boosting the input voltage to the transducer, while measuring the acoustic exposure parameters recommended in international standards. Note-while acoustic exposure parameters like Mechanical and Thermal index (MI and TI, respectively) are well-studied and reported for CFB techniques, the same is not the case with novel SA techniques. For analysis, the image quality metrics of Contrast Ratio (CR), Contrast to Noise Ratio (CNR) and generalized Contrast to Noise Ratio (gCNR) are employed for the SA techniques of Synthetic Transmit Aperture (STA) and Diverging Beam Synthetic Aperture Technique (DB-SAT). The results show that, when the input voltage is increased from 45 to 70 V in PZT transducer, the following improvements in image quality parameters were observed: CR by 15.6% and 21.25%, CNR by 21.39% and 36.23% and gCNR by 14.1% and 21.5% for STA and DB-SAT techniques, respectively. Results also suggest that the considerable imaging depth improvement is achieved for the incremental input voltage till 60 V, with the highest of 7.5% depth improvement at 60 V, above which the tradeoff between the gain in imaging depth and acoustic safety index becomes critical to consider. Recently, transducers having lead magnesium nitrate lead titanate (PMN-PT) piezoelectric single crystals have shown to produce ultrasound images with higher image quality at greater depths, irrespective of the transmit schemes. The same concept of relatively higher output transmitting energy by cost expensive PMN-PT single crystal transducers for the same applied voltage, compared to the traditional lead zirconate titanate (PZT) transducers, explains the enhanced imaging depth. This study is probably the first one that reports the comparison between PMN-PT and PZT transducer, not only in terms of imaging depth but also reporting them in the context of acoustic exposure safety limits in terms of MI and TI. The findings of this study may help system designers to minimize the trade-off between cost and image quality.
Coping Styles as Mediators Between Purpose in Life and Cognitive Function: A Longitudinal Study
Authors: Miller Amanda A. , O’Súilleabháin Páraic S. , Luchetti Martina , Terracciano Antonio , Sutin Angelina R.
Published: January 2025

This study tests associations between purpose in life and coping, and whether coping mediates the association between purpose and cognitive function. Longitudinal data from the Midlife Development in the United States (MIDUS) study were used to investigate associations between purpose at MIDUS I and coping at MIDUS II ( N = 2386). Emotion-focused and problem-focused coping were tested as mediators between purpose and cognitive function (memory, executive function, global cognition) at MIDUS III. Higher purpose was associated with more problem-focused and less emotion-focused coping. Coping partially mediated the association between purpose and cognitive function. Emotion-focused coping partially mediated (14.3%) the effect of purpose on cognitive function. Problem-focused coping partially mediated (16.7%) the association of purpose on episodic memory, but not executive function or global cognition. These findings provide new evidence for links between purpose and coping and suggest coping is one mechanism linking purpose with better cognitive function.
Sleep, Mood, and Economic Preferences
Authors: Nguyen Trung Thong , Duong Duy , Phan Son Dinh
Published: January 2025

This study used daily experimental data from smart bands worn by 142 respondents to investigate the relationship between the number of minutes slept and self-reported mood. The results showed that more minutes of sleep were associated with improved mood. Time preferences, altruism, and trust were also associated with mood. Finally, our analysis revealed that the only mechanism through which sleep affects mood is positive reciprocity. This study contributes to the existing literature by examining the connections among healthy habits, sleep quality, economic preferences, and their effects on mood.
Varieties of altruistic actions across development and culture / Variedades de acciones altruistas a lo largo del desarrollo y entre culturas
Authors: Carlo Gustavo , Partoví Roushanac
Published: January 2025

Altruistic prosocial behaviours are an important subset of prosocial behaviours (i.e., actions that benefit others) that develop across age and can vary across cultures. These behaviours are defined by a selfless motive to assist others with little or no expectation for self-reward and at a cost or risk to oneself. Research has demonstrated several sociocognitive, socioemotive and social correlates of these actions. Importantly, scholars have posited the central role of altruistic prosocial behaviours in reducing and addressing social inequities and injustices, though direct supportive evidence is sparse. First, we briefly review prior theory and research on the development and social correlates of altruistic prosocial behaviours. Second, a new heuristic model of altruistic prosocial behaviours is presented that outlines the elements of varieties of such actions. The model provides avenues for future research that can further our understanding of the correlates and development of distinct forms of altruistic prosocial behaviours across development and cultures. And third, we propose recommendations for future research to significantly advance the developmental scholarship on this important construct.
The Brutalization of the World: Achille Mbembe, Brutalism
Authors: Apata Gabriel O.
Published: January 2025

Achille Mbembe’s latest book addresses some of the existential concerns of the modern age and the power structures that have shaped them. Modernity’s allure has created a false belief in the idea of progress while concealing a destructive streak in human activities. He warns that there is trouble ahead unless humans chart a different course. But is this the lamentation of a Jeremiad or a timely intervention in the current state of the world?
Raising siblings is stressful: Measuring parental emotion regulation in the sibling context
Authors: Kramer Laurie , Ravindran Niyantri , Prather Kellsie
Published: January 2025

Parents’ ability to manage intense emotions in the face of conflictual sibling interactions is a significant challenge that has been linked with various child and parent outcomes. With existing instruments focused on raising a single child, we lack validated instruments to assess dimensions of parental emotion regulation in the context of rearing siblings. We tested the factor structure, reliability, divergent and concurrent criterion validity of a new instrument designed to measure parental emotion regulation ( Parental Emotional Regulation in the Sibling Context Questionnaire) while raising two or more children. Participants, 359 mothers from 35 countries, with two children aged 4- to 8-years, completed the new instrument along with established measures of parental emotion regulation, sibling relationship quality, and children’s emotion regulation. A confirmatory factor analysis supported the utility of the instrument in reliably assessing dimensions of parent emotional regulation (Reactivity and Dysregulation). Evidence for divergent validity stemmed from associations with an established measure of general emotion regulation strategies and evidence for concurrent criterion validity stemmed from associations with children’s sibling relationship quality. Findings have implications for the reliable identification of mothers who are facing emotion regulation difficulties, the design of customized intervention strategies, and the evaluation of prevention and intervention programs.

Authors: Eyadat Ahmad Ali , Abdellatif Hadeel , Almuhana Mohammad , Al-Bataineh Tarique
Published: January 2025

This study investigates the Influence of business intelligence (BI) strategy on enterprise evaluation. It is a comparative study between California State and Jordan. The study’s sample comprises a total of 80 BI experts, with 40 individuals from California State and 40 from Jordan’s market. All participants have specialized expertise in BI. The Snowball Sampling Method is used to choose the intended participants. The research framework applied the Resource-Based View (RBV) theory. A 9-item questionnaire was utilized to gather responses to the main research question. Subsequently, a comparative analysis was conducted between California State and Jordan on this topic. The findings from participants in the California market indicate that BI facilitates easy evaluation of companies and significantly contributes to market competitiveness, reflecting a generally optimistic outlook on the transformative potential of BI within enterprises in California. In contrast, participants in the Jordanian market show that the perception of BI’s Influence on enterprise evaluation leans towards the negative in Jordan, representing a divergence from the more positive perspective observed in the Californian market on the role and influence of BI strategies in contemporary business contexts.

Authors: U Nivya Krishna , Francis PG , Kalarickal Biju , Sebastian Joseph , Suresh Brijesh , Sebastian Irin
Published: January 2025

Objective

To estimate the change in intraoral volume following orthodontic extraction correction in bidentoalveolar protrusion cases and to establish whether there is a significant change in intraoral volume associated with the above treatment.

Materials and Methods

This study was conducted on 15 patients with bidentoalveolar protrusion. Data were collected using cone beam computed tomography before and after orthodontic extraction correction. Pretreatment and post-treatment intraoral volume were determined for each patient from multiplanar reconstructions using Planmeca Romexis viewer software.

Results

The mean pretreatment and post-treatment intraoral volume was 43.055 ± 2.55205 cm3 and 38.4958 ± 2.42266 cm3, respectively. The mean change in intraoral volume was 4.5592 ± 0.72272 cm3.

Conclusion

There was a significant reduction in intraoral volume after orthodontic retraction in bidentoalveolar protrusion cases.
Feasibility analysis of solar and wind energy-powered irrigation pumping systems using reanalysis data–A case of Thiruvananthapuram district in Kerala, southwest region of India
Authors: S R Suresh Lal , G M Joselin Herbert , Vijayan Aswathy
Published: January 2025

This study presents a feasibility assessment of solar photovoltaic and wind energy systems for irrigation at three locations (a coastal lowland location named A, a midland location B, and a highland location C) in Thiruvananthapuram district, Kerala, in India’s southwest region. The solar and wind potentials are determined using the National Solar Radiation Database and Modern-Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data sets, respectively. The technical analyses suggest that site B has the most solar energy potential, while site C has the highest wind energy potential. However, the economic feasibility study reveals that the only suitable location is site B, which has a 10-year simple payback time (SPT). The site has an annual solar energy potential of 1633.85 kWh/kWp, which is enough to pump 3921.24 kL of water to irrigate the majority of crops in one acre.
Factors associated with poor intraoperative perfusion and postoperative complications in otolaryngological autologous tissue transfers: A single-centre retrospective observational study
Authors: Eastlack Steven C , Bellotti Adriano A , Stepp Wesley H , Cadwell Joshua B , Smeltz Alan M
Published: January 2025

The purpose of this study was to identify haemodynamic factors that are associated with tissue hypoperfusion in flap/graft surgical patients that might be modified to reduce perioperative morbidity. We conducted a single-centre, retrospective, observational study of 1355 patients undergoing head and neck flap reconstructions. Logistic regression and chi-square analyses were employed to identify factors which signal perioperative complications. Study endpoints included postoperative lactic acidosis, acute kidney injury (AKI) and early surgical flap revision surgery. Intraoperative data were collected as time-weighted averages of the haemodynamic variables, including pulse pressure variation (PPV), mean arterial pressure, and vasopressor doses. Cumulative volume was used for intravenous (IV) fluids. Relevant patient comorbidities were also included in the analysis. The most common complication was hyperlactataemia (22.9%), followed by AKI (14.1%) and take-back surgery (3.3%). No patient factors were significantly correlated with flap complications. Elevated max PPV was significantly associated with elevated lactate and AKI in univariate regression, but only AKI in the multivariate analysis ( P = 0.003). Case duration was the only variable associated with take-back surgery in the multivariate regression ( P = 0.007); it was also associated with lactic acidosis ( P = 0.003). Neither IV fluid administration nor the use of vasopressors appeared to be associated with study outcomes in the multivariate analysis.
Culprit allergen prevalence in polyreactive individuals reflects prescription trends: A tool for estimating comparative anaphylaxis risk using the example of neuromuscular blocking agents
Authors: Sadleir Paul HM , Goddard Catherine E , Clarke Russell C , Mickle Peri S , Platt Peter R
Published: January 2025

Prescription-event monitoring (PEM) is the current gold standard for determining the risk of rare drug side-effects and comparing the risk between agents; however, spontaneous or prompted reporting schemes have low case-detection rates and exposure may be difficult to estimate. A novel method is described that allows a comparative adverse event rate between two drugs to be estimated—based on patterns of cross-reactivity—requiring only a sample of cases and no direct knowledge of drug exposure rates. Agreement was compared between the novel method and historical estimates of risk using PEM for comparative risk of rocuronium versus vecuronium anaphylaxis. The novel method was applied to a sample of patients investigated by the Western Australian Anaesthetic Drug Reaction Clinic over a 21-year period. Relative population exposure was estimated from the number of patients with either rocuronium or vecuronium anaphylaxis subsequently shown to be reactive on skin testing to both agents. This was used to correct the total number of cases of hypersensitivity triggered by each agent. Measures of spread were by bootstrap sampling. Historical estimates were gathered by literature review. Additional comparisons of agreement between estimates made by the novel method and PEM were made using cross-reactivity data and PEM rates reported in the literature. There was agreement between estimates of comparative anaphylaxis risk between the novel method and PEM. Two-hundred and twenty-eight cases of anaphylaxis were observed, 89% caused by rocuronium. Patients reactive to both agents were more likely to be female, and had a higher acute mast cell tryptase level. Patients with a history of rocuronium anaphylaxis were more likely to be reactive to one agent only (69% vs. 33%, P < 0.01). It was estimated that rocuronium was prescribed 3.9 times more frequently than vecuronium. When the observed proportion of cases was corrected for exposure rate, the risk of rocuronium anaphylaxis was 2.2 times that of vecuronium (95% confidence interval 1.7 to 2.8). The median risk from historical estimates was 4.7 times, while the previous PEM estimate in Western Australian was 3.0 times. Using a subgroup of patients susceptible to the same side-effect of two drugs, the relative exposure rate and corrected comparative risk of an adverse effect can be estimated for a population. Using this technique, which requires assessment only of cases to estimate relative exposure rates, we have estimated that the risk of anaphylaxis from rocuronium to be 2.2 times that of vecuronium in Western Australia.
The effect of type of anaesthetic on delirium after surgery for acute hip fracture: An instrumental variable analysis to assess causation
Authors: Tanios Anna-Marie G , Gallagher Emily L , McManus Michael S , Riordan John A , Harris Ian A , Harvey Lara A
Published: January 2025

Delirium is the most common in-hospital complication affecting older adults with acute hip fractures. Current evidence demonstrates inconsistent associations between anaesthetic type for acute hip fracture surgery and postoperative delirium. Using the Australian and New Zealand Hip Fracture Registry database, we conducted a retrospective cohort study of patients aged 50 years and over who underwent acute hip fracture surgery between 2015 and 2020. The incidence of delirium in patients who received general anaesthesia alone or combined with a regional technique, versus those who received spinal or regional anaesthesia was assessed. Multivariable multilevel logistic regression was used to test associations between anaesthetic type and delirium controlling for known confounders. Finally, given hospital variation in preference for anaesthetic type, an instrumental variable analysis was performed to include the effect of both known and unknown confounding. Of 35,252 patients, 25,682 (72.9%) patients received general anaesthesia, and 9570 (27.2%) patients received spinal or regional anaesthesia for their hip fracture surgery. A higher proportion of patients who received general anaesthesia developed delirium than those who received spinal or regional anaesthesia (40.6% vs. 35.7%, odds ratio (OR) 1.23, 95% confidence intervals (CI) 1.18 to 1.30, P < 0.0001). After adjusting for known confounders, general anaesthesia patients were at slightly increased odds of developing delirium (OR 1.14, 95% CI 1.04 to 1.25, P = 0.0052). However, the instrumental variable analysis found no statistically significant difference between groups (OR 1.03, 95% CI 0.99 to 1.07, P = 0.141). Therefore, while a weak association was found between general anaesthesia exposure and postoperative delirium, an instrumental variable analysis to compensate for unmeasured confounding showed no causal association between general anaesthesia and postoperative delirium.

Review of Lighting Control Equipment and Applications: Minimizing energy consumption while properly lighting for use of space
Authors: Verderber R.R.
Published: January 2025

Many types of lighting control equipment permit the automatic management of lighting systems. Lighting control equipment can be used to lower light levels, turn lights on and off on a schedule, and respond to the availability of natural light or the presence of occupants. Each of these operations minimizes the energy consumed while providing the proper illumination for occupants’ use of the space.

The choice of lighting control system depends on its particular application (retrofit, renovation, or new construction). This presentation will attempt to provide a basis for selecting the control equipment and the control strategies (light reduction, scheduling, tuning, lumen depreciation, daylighting, load-shedding) most apropos to an application, and presenting the important cost factors (initial, operating, installation, supply circuit layout, building design) that one must consider for each application.
“Stressed Out”: The Conditional Effect of Organizational Belongingness on Burnout Among Street-Level Bureaucrats
Authors: Shay Laine P. , Rauhaus Beth M.
Published: January 2025

A substantial body of literature examines the determinants of burnout levels among street-level bureaucrats. However, one factor that has not been investigated in relation to the reported burnout levels among public employees is the perceived level of belonging within an agency. We develop a theoretical rationale linking an agency’s level of belongingness with the employee’s reported level of feeling burned-out, with the expectation that this relationship is conditioned by the employee’s gender. When analyzing the perceptions among local law enforcement officers, we find evidence to support our theoretical expectations. For women officers, we find that an increase in the perception that the agency has a culture of belongingness is associated with a decrease in feeling burned out. We find that organizational belongingness has a weaker effect among male officers. These findings contribute to our understanding of how organizational belongingness within a public agency can influence the workforce morale for certain employees.
Constructing Equity in Urban Climate Mitigation Planning
Authors: Elmallah Salma
Published: January 2025

Though urban climate policy increasingly centers “equity,” the term remains amorphous and is often sidelined for technocratic framings. This paper investigates how cities arrive at equity aspirations and how, if at all, “equity” remakes climate planning processes. Using qualitative case studies in Oakland and San Jose, California, this paper argues that equity is constructed relationally, with consultants at the center. Consultants are positioned as both technical and procedural experts, allowing them to advocate for or gatekeep equity aspirations. The turn to equity both challenges technocratic consultant-driven planning practices and reproduces consultants as procedural experts.
Standing Together: An Investigation of the Social Support Deterioration Deterrence Model 1 Year After the Club Q Shooting

Both mass shootings and acts of bias-motivated violence have significant psychological consequences, as survivors commonly experience psychological distress in the form of depression symptoms, anxiety symptoms, and posttraumatic stress symptoms (PTSS) following the event. Moreover, increases in psychological distress are common near the year mark of a traumatic event. However, little is currently known about how communities affected by the intersection of bias-motivated violence and mass shootings are affected by these events in the longer term. The present study therefore investigated survivors’ psychological reactions around the 1-year mark of the Club Q shooting, which targeted members of the Colorado Springs lesbian, gay, bisexual, trans, queer and questioning (LGBTQ+) community. Specifically, informed by the social support deterioration deterrence model, this study used path analysis to explore how exposure to the shooting, community solidarity, and receiving social support were associated with psychological distress among N = 64 LGBTQ+ individuals in Colorado Springs. Results indicated that higher community solidarity was associated with more severe psychological distress, a latent variable comprised of depression symptoms, anxiety symptoms, and PTSS, β = .39, p = .001, but no other predictors were statistically significant. These results suggest that community solidarity may increase vulnerability to psychological distress, perhaps because these individuals are more personally affected when their community is targeted and harmed. This study also highlights the need for ongoing community support and healing efforts around the 1-year mark of a bias-motivated mass shooting.

Utilization of cangrelor following coronary artery stent placement as a bridge to cardiac surgery has been previously described in the literature. However, the use of cangrelor as bridge therapy to cardiac surgery for endovascular revascularization is lacking. We describe a case involving a 47-year-old female who developed a left lower extremity tibioperoneal trunk non-obstructing arterial dissection following extracorporeal membrane oxygenation decannulation, requiring repair with a Viabahn endoprosthesis. To maintain stent patency, as well as treat the patient’s multi-vessel coronary disease and left ventricular thrombus, triple therapy with cangrelor, aspirin, and bivalirudin was utilized as the patient was optimized for a coronary artery bypass procedure. Our case describes a unique antiplatelet and anticoagulation strategy in a complex patient involving a multi-disciplinary team.

Present work effectively highlights the improvement of flame retardant behaviour and thermal stability achieved through the incorporation of DOPO-functionalized SiO2 nano- composites into epoxy composites. The successful functionalization and existence of chemical bonding between SiO2 nanoparticles and DOPO was confirmed using FT-IR and TGA. Among the varied weight percentage concentration of reinforcement used, 1.5 wt% DOPO-functionalized SiO2 epoxy composites exhibited significantly improved thermal properties, including high char yield and enhanced glass transition temperature compared to those of neat epoxy matrix. Notably, the 1.5 wt %DOPO-functionalized SiO2 reinforced composites possess V-0 ratings in the UL-94 vertical burn test, underscoring their remarkable flame retardancy, which further demonstrate the effectiveness of integrating DOPO functionality into the epoxy matrix. This integration significantly contributes to improved flame retardancy, confirming the potential of these modified nanocomposites for applications requiring enhanced thermal stability and flame retardant behaviour. The present study provides a promising approach for the development of advanced epoxy composites with superior fire safety characteristics, exploiting the unique properties of DOPO-SiO2 functionalized reinforcements.

In industries like shipbuilding and aerospace, the ongoing need for advanced epoxy resins possessing superior mechanical strength and flame-retardant characteristics remains critical. In this study, a silicon-phosphorus blended resin (ED./EB) was synthesized using 10-(2,5-dihydroxy phenyl)-10-hydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO-HQ) and hydroxyl-terminated silicone oligomer (Z-6018) as precursors. In comparison to epoxy resin (E−51), experimental results indicated a 16.7% increase in the tensile strength of ED/EB and a 20.7% increase in impact strength. The enhancement and toughening of the resin were simultaneously achieved through the silicon-phosphorus synergistic modification. The flame retardancy test indicates that ED./EB combines the outstanding smoke suppression of silicone modified resin (EB) with the high LOI of phosphorus modified resin (ED-27), while also decreasing the flame growth index (FIGRA) of the resin. After undergoing combustion, the silicon-phosphorus collaboration within the ED/EB material yielded a dense protective covering on the surface. This covering effectively governed the emission of smoke particles and heightened the residual mass. This work elucidates the impact of silicon-phosphorus synergy on the mechanical and flame-retardant properties of the resin, which is of great significance for developing high-performance resins.

Published: January 2025

The frequent failures of the pantograph pose a significant risk to the reliable operation of the pantograph-catenary systems (PCS). However, pantograph failures have not received sufficient attention in PCS research, where studies typically focus on system interactions rather than on the pantograph itself. Moreover, high precision load spectrum fitting is also one of the focuses of load spectrum research, therefore, a semi-data-driven high-precision spatial load spectrum fitting method for the pantograph is proposed in this paper. First, a PCS model with a rigid-flexible hybrid pantograph was established and validated to obtain the spatial load at the hinge of the upper arm. Second, an improved parametric load spectrum fitting method was proposed based on single-function estimation methods and chi-square test, while Gaussian kernel density estimation (GKDE) was also employed for fitting and subjected to the chi-square test. Third, the goodness-of-fit for all methods was evaluated using multiple indicators, followed by a comprehensive ranking to identify the optimal fitting method. Finally, a process for determining the optimal load spectrum fitting method was summarized from the above procedures. The results indicate that single functions exhibit poor adaptability to the data due to the limitations of prior knowledge, the improved method proposed in this paper overcomes this problem and enhances the accuracy of individual fittings. Furthermore, compared to the GKDE method, the fitting accuracy was improved by more than 30%, with a maximum improvement of 69.13%, this provides an effective data processing approach for fatigue assessment and life prediction.

The enhancement of accuracy of force measurement is important for aerodynamic force measurements in high-speed facilities. It is essential to evaluate the sensitivity of a force recovery technique for different forces experienced by the body. Very few algorithms are available for accurate recovery of forces experienced by the model in the high-speed facilities. In regards to this, the sensitivity and accuracy of two force recovery algorithms, namely support vector regression (SVR) and genetic algorithm (GA), have been examined for the force recovery in shock tube experiments. The current study focuses on the use of GA for the very first time for dynamic calibration and prediction of transient short duration force in impulse facilities. Support vector regression is another technique that has been used for the first time for force recovery in impulse facilities. The available methods of force recovery like deconvolution and adaptive neuro fuzzy inference system (ANFIS) have certain limitations in regards to the accuracy of recovered forces and are not suitable for all experimental conditions and force magnitudes. It is essential to obtain a force recovery algorithm that can be used for all conditions of force magnitudes and experimental conditions. This is ensured by a sensitivity study and it is found that both support vector regression and genetic algorithm provide high accuracy in calibration as well as shock tube experiments. These techniques are found to be accurate and sensitive towards the changes in the measured force due to introduction of spikes of various lengths on the model.
