Notes Toward a Materialist Aesthetics
Authors: Hlito Alfredo
Published: May 2023

This introductory study analyzes two key texts from the short-lived Argentine collective, the Asociación Arte Concreto-Invención (Association of Concrete Art-Invention, or AACI). Published in 1946 in the same issue of the group's official organ, they collectively theorize the “co-planar,” the AACI's key contribution to the history of abstract and concrete painting. While Maldonado's text offers a historical reconstruction of the genealogy of the co-planar as the culmination of modernist investigations of the plane and the problem of composition, Hlito's text outlines the understanding of Marxist materialism and dialectics that underpinned this particular take on the task of modernism.
From Fiction to Function: Imagining New Instruments through Design Workshops
Authors: Sullivan John , Wanderley Marcelo M. , Guastavino Catherine
Published: May 2023

This article introduces a series of workshop activities carried out with expert musicians to imagine new musical instruments through design fiction. At the workshop, participants crafted nonfunctional prototypes of instruments they would want to use in their own performance practice. Through analysis of the workshop activities, a set of design specifications was developed that can be applied to the design of new digital musical instruments intended for use in real-world artistic practice. In addition to generating tangible elements for instrument design, the theories and models utilized, drawn from human–computer interaction and human-centered design, are offered as a possible model for merging the generation of creative ideas with functional design outputs in a variety of applications within and beyond music and the arts.
The COVID-19 Pandemic and Major Power Rivalry in Africa
Authors: Shangwe Muhidin J.
Published: May 2023

Not immune from the nature of international relations, the COVID-19 pandemic has invoked the polarizing dichotomies of East-West and North-South as attempts to forge a collective response to fight the disease have only attained mixed results. The discourse of Africa being a battleground of competing foreign interests has consequently emerged. These foreign interests are mainly expressed in terms of economic, security and political benefits. While the pandemic has not changed the motives of competition, it has contributed to new forms of rivalry in what has become to be known as ‘coronavirus diplomacy.’ This paper reveals that the pandemic is being used to advance political, economic and strategic interests. It thus divulges that, efforts by major powers to help African countries deal with the disease, while appreciated, are not entirely benign. At the heart of such efforts are the “fixed universals” inherent in the realist tradition i.e., state, interest and power.

The full-scale war in Ukraine negatively impacted populations of urban and semi-urban animals. This study examines the effects of war-related damages on urban populations of bats in Kharkiv city (NE Ukraine) during 2022. Our findings suggest that 45.1% of buildings used as wintering roosts for N. noctula were either partially damaged or completely destroyed by shellings, which may have led to the direct killing of approximately 7,000 bats. Additionally, the war-damaged urban environments in Kharkiv serve as a deadly trap for bats during the period of autumn migration or swarming. Bats flew into buildings’ interiors through windows that were left open or broken by blast waves, resulting in entrapment. The total number of N. noctula trapped inside buildings damaged by shelling was 2,836 individuals, with a death rate of approximately 30%. The group size of trapped bats was more numerous than in previous years, and the main findings were concentrated in war-damaged districts of the city.
On the identity of Pronotonyx laevis (Miers, 1884) (Crustacea: Brachyura: Pilumnidae)
Authors: AHYONG SHANE T. , NG PETER K.L.
Published: May 2023

The poorly known brachyuran crab, Pronotonyx laevis Ward, 1936, from northern Australia, is redescribed based on type and other material. We document adults of both sexes and confirm the taxonomic placement of the Pronotonyx in the Pilumnidae. Pronotonyx is most similar to the Australian Pseudocryptocoeloma parvum Ward, 1936, differing in features of the carapace and pereopods.
Improving Vortex Position Accuracy with a New Multiscale Alignment Ensemble Filter
Authors: Ying Yue , Anderson Jeffrey L. , Bertino Laurent
Published: May 2023

A multiscale alignment (MSA) ensemble filtering method was introduced by Ying to reduce nonlinear position errors effectively during data assimilation. The MSA method extends the traditional ensemble Kalman filter (EnKF) to update states from large to small scales sequentially, during which it leverages the displacement vectors derived from the large-scale analysis increments to reduce position errors at smaller scales through warping of the model grid. This study stress tests the MSA method in various scenarios using an idealized vortex model. We show that the MSA improves filter performance as number of scales (Ns) increases in the presence of nonlinear position errors. We tuned localization parameters for the cross-scale EnKF updates to find the best performance when assimilating an observation network. To further reduce the scale mismatch between observations and states, a new option called MSA-O is introduced to decompose observations into scale components during assimilation. Cycling DA experiments show that the MSA-O consistently outperforms the traditional EnKF at equal computational cost. A more challenging scenario for the MSA is identified when the large-scale background flow and the small-scale vortex are incoherent in terms of their errors, making the displacement vectors not effective in reducing vortex position errors. Observation availability for the small scales also limits the use of large Ns for the MSA. Potential remedies for these issues are discussed.
Gracilis Muscle Interposition: A Valuable Tool for the Treatment of Failed Repair of Post-partum Rectovaginal Fistulas—A Single-Center Experience
Authors: Strassmann Victor , Silva-Alvarenga Emanuela , Emile Sameh Hany , Garoufalia Zoe , DaSilva Giovanna , Wexner Steven D.
Published: May 2023

Introduction

Rectovaginal fistulas (RVFs) account for approximately 40% of anorectal complications from obstetrical trauma. Treatment can be challenging requiring multiple surgical repairs. Interposition of healthy transposed tissue (lotus or Martius flap or gracilis muscle) has been used for recurrent RVF. We aimed to review our experience with gracilis muscle interposition (GMI) for post-partum RVF.

Methods

A retrospective analysis of patients who underwent GMI for post-partum RVF from February 1995 to December 2019 was undertaken. Patient demographics, number of prior treatments, comorbidities, tobacco use, postoperative complications, additional procedures, and outcome were assessed. Success was defined as absence of leakage from the repair site after stoma reversal.

Results

Six of 119 patients who underwent GMI did so for recurrent post-partum RVF. Median age was 34.2 (28-48) years. All patients had at least 1 previously failed procedure [median: 3 (1-7)] including endorectal advancement flap, fistulotomy, vaginoplasty, mesh interposition, and sphincteroplasty. All patients underwent fecal diversion prior to or at initial procedure. Success was achieved in 4/6 (66.7%) patients; 2 underwent further procedures (1 fistulotomy and 1 rectal flap advancement) for a final 100% success rate as all ileostomies were reversed. Morbidity was reported in 3 (50%) patients, including wound dehiscence, delayed rectoperineal fistula, and granuloma formation in one each, all managed without surgery. There was no morbidity related to stoma closure.

Conclusions

Gracilis muscle interposition is a valuable tool for recurrent post-partum RVF. Our ultimate success rate in this very small series was 100% with a relatively low morbidity rate.
TV Advertising and Online Sales: A Case Study of Intertemporal Substitution Effects for an Online Travel Platform
Authors: Lambrecht Anja , Tucker Catherine , Zhang Xu
Published: May 2023

Digital technologies lead consumers to engage with companies online after they see TV ads, and firms increasingly wish to coordinate TV advertising in real time with online marketing activities. As a result, firms are keen to measure how TV advertising affects consumers’ online behavior, but a key question is over what window of time to measure this effect. The standard industry practice of using short attribution windows around an ad to measure a causal effect may miss the possibility that consumer behavior shifts over time due to, for example, intertemporal substitution. The authors collaborate with an online travel platform and evaluate the results of a field test in which part of the country was exposed to TV ads while another part of the country formed a control group. Using the synthetic difference-in-differences approach, the authors find that TV advertising leads to an instantaneous increase in online browsing and sales. However, they also document evidence for intertemporal substitution: consumers appear to move their online activities forward in time in response to TV advertising, leading to lower browsing and lower sales at times when no ad is airing. The authors further explore the effects of TV advertising on channel choices, device choices, and promotion usage and discuss the implications for advertisers and the ad-measurement industry.
A theory of jihadist beheadings
Authors: Brzezinski Marek K
Published: May 2023

Why do some jihadist organizations engage in beheadings while others do not? Although beheadings have become a signature tactic of the contemporary global jihadist movement, I show that most jihadist groups perpetrate few or no beheadings and only a minority have adopted beheading as a consistent part of their repertoire of violence. Such variation exists even among ideologically similar ‘Salafi-jihadist’ groups, suggesting that ideology alone cannot explain why such violence occurs. Instead, I argue that the use of beheadings is shaped by a combination of local strategic context and transnational ties. Beheadings are strategically useful to jihadist groups engaged in insurgency as a means of deterring civilian collaboration with the enemy, demoralizing enemy combatants and attracting foreign recruits. But the use of beheading is also costly for such groups, notably because of its tendency to alienate potential civilian supporters. Whether or not particular jihadist groups use beheadings depends largely on whether they can afford to ignore these costs. Jihadist insurgents who control significant territory are less sensitive to civilian attitudes because of their ability to obtain support through coercion and are therefore more likely to perpetrate beheadings. The use of beheadings is also shaped by transnational ties: organizations that seek formal affiliation with transnational jihadist networks are more likely to calculate that the benefits of using extreme violence to attract transnational support outweigh its costs. I test this theory using an original dataset of over 1,500 beheading events perpetrated by jihadist organizations between 1998 and 2019.
Perceived Family Support Buffers the Impact of PTSD-Depression Symptoms on Suicidal Ideation in College Students
Authors: Blessing Alexis , Russell Patricia , DeBeer Bryann B. , Morissette Sandra B.
Published: May 2023

Students reporting symptoms of posttraumatic stress disorder (PTSD) and depression are at increased risk for suicidal ideation, putting them at greater risk for suicidal behavior and attempts. Perceived social support is a robust protective factor against the impact of PTSD and depression on suicidal ideation in college students, however different forms of social support (family, friends, significant others) may have greater influence on this association. In the current study, the influence of the different types of perceived social support on the relationship between PTSD-depression symptoms and suicidal ideation in college students were examined. College students ( N = 928; 71% female) were recruited in part of a cross-sectional survey study examining the role of mental health on education functioning. A hierarchical regression indicated that PTSD-depression symptoms (b = .27, p < .001) and perceived family support (b = −.04, p < .01) were significantly associated with current suicidal ideation, while perceived support from friends (b = −.02, p = .417) and significant others (b = −.01, p = .301) were not. Perceived family support interacted with PTSD-depression symptoms (b = −.03, p < .05) to weaken the positive influence of symptoms on current suicidal ideation. Perceived family support appears to be the significant component of social support that moderates the relationship between PTSD-depression symptoms and suicidal ideation. Future research should focus on strengthening family support as a potential mechanism to mitigate suicide risk among college students who may be away from their families for the first time.
Attentional Biases Towards Body-Related Stimuli in Healthy Males: A Systematic Review
Authors: Kirby Alexandra S. , Jenks Rebecca , Walsh Francesca , Duncan Michael
Published: May 2023

Recent literature has discussed the role of attentional biases towards body-related stimuli. Specific foci have been on those with high levels of body image concerns and female samples. Unfortunately, there has been limited focus on male samples within existing literature. The aim of the current study was to provide a critical synthesis of the findings of existing studies exploring attentional biases in adult males towards body-related stimuli. Critical synthesis of the findings of 20 studies explored four key methodologies: eye-tracking, dot-probe, visual search, and other methodologies (e.g. ARDPEI task). The current review provides evidence of specific attentional biases towards body-related stimuli in adult males experiencing body image concerns. Similar patterns of attentional biases are also demonstrated in males with body image pathologies. However, there appears to be distinct patterns of attentional biases for male and female participants. It is recommended that future research considers these findings and utilises measures developed specifically for male samples. Furthermore, additional variables require further attention, i.e. reasons for engaging in social comparison and/or engaging in physical activity.
Spatial Crisis and the Experimental Production of Urban Space in Franco’s Spain: The History of Madrid’s Poblados Dirigidos
Authors: Ofer Inbal
Published: May 2023

The article analyzes the ideological reasoning, planning rationale, and construction of controlled/satellite neighborhoods ( poblados dirigidos) in the metropolitan area of Madrid during the 1950s and 1960s. Poblados dirigidos were compact and minutely planned barrios on which the Franco regime (1939-1975) hinged its hopes for re-directing urban growth and controlling informal urbanization. While the phenomenon of poblados dirigidos was investigated by several Spanish architects and urban planners, their work focused mostly on the design of these neighborhoods, the structure of their housing units, and the innovative construction techniques. The current article suggests that the spatial crisis that drove the dictatorship to embrace the planning module of poblados dirigidos cannot be understood in isolation from the political and economic challenges faced by the regime during its “interim decades.” These challenges led to a progressive shift in the regime’s territorial representations and to a partial shift in its spatial practices, which the article analyzes.
Asynchronous event-triggered guaranteed cost control of two-dimensional Markov jump Roesser systems
Authors: Liu Jiazheng , Yang Yang , Zhu Yaodong , Zhang Chenjie
Published: May 2023

This paper deals with the problem of asynchronous event-triggered guaranteed cost control for two-dimensional Markov jump systems in Roesser model. The hidden Markov model is introduced to characterize the asynchronous phenomenon induced by imperfect mode detection, and a hidden Markov model-based event-triggered mechanism is employed in controller design to reduce the communication burden of the network. By using the quadratic Lyapunov function technique, some sufficient criteria are developed to ensure the asymptotic stability of the addressed system with a guaranteed cost value under three different boundary conditions. Finally, an optimization algorithm with linear matrix inequality constraints is formulated to design the optimal asynchronous event-triggered guaranteed cost control law, and a simulation example is considered to illustrate its validity.
What Do Investors Value? A Multidisciplinary Review
Authors: Guo Wei , Yu Tieying
Published: May 2023

This study offers a comprehensive and multidisciplinary review of the research on the antecedents of investor valuation in the management, accounting, and finance literature. Despite the growing recognition of the importance of investors and financial markets, our current understanding of the factors that drive investor valuation remains incomplete. To address this gap, we classify the existing literature on investor valuation into three perspectives: social, cognitive, and economic. The social perspective examines how social forces, such as institutional norms and pressure, shape investor valuation. The cognitive perspective focuses on the psychological underpinnings of investors’ valuation decisions, while the economic perspective emphasizes how investors determine the value of firms through rational cost-and-benefit calculations. This review compares the research on investor valuation in the management literature to that in the accounting and finance literature, identifying gaps in the management literature and discussing emerging trends that may influence investor valuation. The review also proposes an agenda for future research. In conclusion, this study illuminates the intricate and multifaceted nature of investor valuation, as well as the underlying factors that influence it.
Navigating professionals’ conditions for co-production of victim support: A conceptual article
Authors: Würtz Jensen Julie Mathilde , Thunberg Sara
Published: May 2023

From previous research it is well known that victimization can have various short- and long-term consequences resulting in a need for support to cope with the victimization. Research also shows, however, that not all victims of crime seek or receive support. One cause of this might be the conditions and constraints that affect professionals’ matching of support services with individual victims’ needs. The purpose of the present conceptual paper is to discuss how professionals can co-produce support services with the individual victim and if needed engage suitable external organizations for the purpose of adapting support services to the individual victim’s needs, while also considering the complex field of constraints that professionals need to navigate during this process. The paper makes two main contributions. First, it conceptualizes the complex field of constraints as consisting of five sets of conditions (mandatory, local, professional, support-user, and inter-organizational conditions), which professionals must navigate during the co-production of victim support services. Second, the paper suggests a seven-step process of how professionals can navigate this complex field during co-production of victim support services’ activities with the individual victim, and potentially those of external organizations as well.
Early Educators’ Perceptions of Behavior
Authors: O’Grady Courtney E. , Ostrosky Michaelene M.
Published: May 2023

We explored how teachers perceived challenging behavior in contrast to behaviors that exemplify social-emotional competence, and how descriptions of behavior varied based on child demographics such as gender, race/ethnicity, and disability status. Using a DisCrit lens, we conducted this study under the assumption that perceptions of behavior may be informed by teachers’ implicit biases. Fourteen preschool teachers shared their perspectives on behaviors they saw in the classroom, as exemplified by descriptions of the two children they considered the most socially-emotionally successful, A/Z, and the two they considered the most challenging, C/E. Children in the A/Z group were 54% female, 46% male, 54% White, 29% Black, and 82% did not receive special education services or need screening. Children in the C/E group were 86% male, 14% female, 46% Black, 36% White, and 75% were either receiving special education services or identified by teachers as needing a referral for screening. Positive A/Z behaviors included being a model, leader, or helper; having good play skills, manners, and verbal skills; and loving to learn. The challenging behaviors for C/E students included being hard to connect with; engaging in physical aggression and defiance; and having communication difficulties and poor self-regulation skills. These findings help us understand the role of implicit bias, systems issues, and the importance of culturally responsive practices in early childhood settings.

Authors: Otgonbaatar Chuluunbaatar , Jeon Pil-Hyun , Ryu Jae-Kyun , Shim Hackjoon , Jeon Sang-Hyun , Ko Sung Min , Kim Hyunjung
Published: May 2023

Background

The reference protocol for the quantification of coronary artery calcium (CAC) should be updated to meet the standards of modern imaging techniques.

Purpose

To assess the influence of filtered-back projection (FBP), hybrid iterative reconstruction (IR), and three levels of deep learning reconstruction (DLR) on CAC quantification on both in vitro and in vivo studies.

Material and Methods

In vitro study was performed with a multipurpose anthropomorphic chest phantom and small pieces of bones. The real volume of each piece was measured using the water displacement method. In the in vivo study, 100 patients (84 men; mean age = 71.2 ± 8.7 years) underwent CAC scoring with a tube voltage of 120 kVp and image thickness of 3 mm. The image reconstruction was done with FBP, hybrid IR, and three levels of DLR including mild (DLRmild), standard (DLRstd), and strong (DLRstr).

Results

In the in vitro study, the calcium volume was equivalent ( P = 0.949) among FBP, hybrid IR, DLRmild, DLRstd, and DLRstr. In the in vivo study, the image noise was significantly lower in images that used DLRstr-based reconstruction, when compared images other reconstructions ( P < 0.001). There were no significant differences in the calcium volume ( P = 0.987) and Agatston score ( P = 0.991) among FBP, hybrid IR, DLRmild, DLRstd, and DLRstr. The highest overall agreement of Agatston scores was found in the DLR groups (98%) and hybrid IR (95%) when compared to standard FBP reconstruction.

Conclusion

The DLRstr presented the lowest bias of agreement in the Agatston scores and is recommended for the accurate quantification of CAC.

Authors: Moradpour Moein , Azizinik Fahimeh , Zeidabadi Hamideh , Ghomi Zahra , Shakki Katouli Fatemeh , Tavakol Elham , Torabi Parizi Shabnam
Published: May 2023

Background

Breast cancer mainly affects women aged >50 years; however, younger women may also have advanced breast cancer, so early detection is important.

Purpose

To collect and review the imaging findings of women aged <30 years with breast cancer to find better diagnostic approaches for the early diagnosis of breast cancer in young women.

Material and Methods

In this study, 45 patients aged <30 years with a diagnosis of breast cancer were evaluated. Imaging assessments were performed based on ultrasound, mammography, and magnetic resonance imaging (MRI) findings. Finally, the findings were compared with the pathological results.

Results

Predominant findings in ultrasound included irregular spiculated mass in 59.4%. In mammography, irregular high-density mass (46.5%) and suspicious micro calcification (42.8%) were the most common findings. In MRI, the predominant feature was a heterogeneous enhancing mass with an irregular shape and irregular margin (81%) with a 45% plateau and 36% washout kinetic pattern. In the pathology assessment, invasive ductal carcinoma was the most common finding (84.4%). All three modalities—MRI, ultrasonography, and mammography—are valuable, with sensitivities of 100%, 93.3%, and 90%, respectively.

Conclusion

Ultrasound, mammography, and MRI are highly sensitive and accurate tools for detecting breast cancer lesions in young women. Regular clinical breast examination with breast self-examination, and in suspected cases, ultrasound as the first imaging modality followed by mammography and/or MRI are the preferred diagnostic approach.
A case of toxic epidermal necrolysis associated with lenvatinib and sintilimab therapy for intrahepatic cholangiocarcinoma
Authors: Gong Yinhua , Mao Jinzhu , Liu Ming , Gao Jie
Published: May 2023

Lenvatinib is used as the first-line treatment for intrahepatic cholangiocarcinoma. Sintilimab is a programmed cell death receptor-1 (PD-1) antibody used in the treatment of solid tumors. We present the case of a 78-year-old man with fatal toxic epidermal necrolysis (TEN) associated with the use of sintilimab followed by lenvatinib. This patient, who presented with intrahepatic cholangiocarcinoma, first received immunotherapy with sintilimab according to the standard schedule of 200 mg every 3 weeks. The patient began to receive 8 mg of lenvatinib daily 1 day after sintilimab therapy was initiated. Multiple erythematous papules and blisters appeared on the patient’s face and trunk and gradually spread to his arms and legs, and the lesions extensively involved >30% of the body surface area 18 days after lenvatinib initiation. The patient stopped taking lenvatinib on the next day. The skin rash quickly progressed over 1 week to a tender, exfoliative dermatosis. Despite treatment with high-dose steroids and intravenous immunoglobulin, the patient died. To the best of our knowledge, this is the first case of TEN associated with the use of sintilimab followed by lenvatinib. Early diagnosis and treatment of possibly fatal TEN reaction secondary to anti-PD-1 antibody therapy followed by lenvatinib is necessary.
Improved Method for Calculating the Gauge of Railway Vehicles Considering the Non-Linearity of Suspension Systems
Authors: Shuangxi Chen
Published: May 2023

An improved method for calculating the gauge of railway vehicles is proposed in this study, which can provide more reasonable results for vehicles with nonlinear springs in the suspension system. Typical mechanics models of nonlinear springs are built and then introduced into the calculation formulas described in the Chinese Gauge Standard CJJ 96-2018. The relative displacement equations for the primary and secondary suspensions are defined, based on the calculation formulas, and an iterative algorithm based on Taylor expansion is applied to solve these nonlinear equations. By solving the equations, the relative displacements of the control points of the suspension system are obtained and the parameters for gauge calculation are updated. The updated parameters are then used to calculate the transverse and vertical displacements of the car body, bogie, unsprung components, flange, and tread, and to determine the quantity of throw of the vehicle profile. Finally, a numerical example is given to verify the feasibility, accuracy, and applicability of the method, and the results are also compared with those calculated from European Standard EN 15273. The method is applicable to a wide range of railway vehicles with nonlinear suspension systems, giving more reasonable results compared with existing calculation methods.
SIGeR-RV: A Web-Geographic Information System-Based System for Risk Management of Road Networks Exposed to Natural Hazards
Authors: Chamorro Alondra , Echaveguren Tomás , Pattillo Carlos , Contreras-Jara Manuel , Contreras Marta , Allen Eduardo , Nieto Natalia , de Solminihac Hernán
Published: May 2023

The consequences of natural hazards are frequently estimated by the direct cost of recovering damaged infrastructure and the indirect costs to road users, economic activities, and impacts on society. Road networks are crucial in economic systems, logistic chain continuity, accessibility, mobility, and the evacuation of population during and after extreme events. Risk management systems (RMS) are used to estimate the potential consequences of natural events and to assess strategies for risk reduction. These commonly assess hazards, assets exposure, economic losses, and risk mitigation actions, among others. The general framework of RMS can be adapted to different scenarios. Still, local characteristics, such as the types of hazards and physical assets, cannot always be directly adopted from these systems. This study discusses the development of SIGeR-RV, an RMS developed in Chile for road networks exposed to multiple natural hazards. The RMS was implemented in a web-based geographic information system platform able to display hazard maps, quantify risk levels, prioritize mitigation strategies, and estimate direct and indirect costs and social vulnerability. The content and various capacities of the system are detailed, following the steps marked in its framework. This first version of SIGeR-RV considers seismic hazard, volcanic lahars, and hydro-meteorological hazards that affect road platforms, bridges, tunnels, and cut slopes. The system currently serves as a tool for the Ministry of Public Works of Chile and other decision makers to estimate budget requirements for increasing resilience of the road network, identifying vulnerable road segments, and assessing the socioeconomical impacts of risk reduction.
Evaluating Social Equity of Transit Accessibility: A Case of Salt Lake County, U.S.
Authors: Zinia Faria Afrin , Bhandari Pukar , Tuffour Justice Prosper , Hong Andy
Published: May 2023

Addressing social equity in public transportation remains a key challenge for many cities and planning organizations. In this study, we examined social equity dimensions of accessibility to light rail transit (LRT) stations in Salt Lake County, U.S., by employing two novel methods. First, we used the two-step floating catchment area (2SFCA) method to examine the interactions between the demand and supply of the public transit service. Second, we developed geospatial models to account for spatial bias in transit equity analysis. Results showed little evidence of inequitable access to LRT stations in Salt Lake County. The accessibility to LRT stations appeared to be generally higher in the downtown and transit catchment areas with a higher concentration of low-income and ethnic minority populations. Furthermore, we found statistically significant associations between higher transit accessibility and households which are not homeowners, and/or do not own a private motor vehicle. Our findings suggest that transit investments in Salt Lake County could leverage substantial transportation accessibility opportunities to achieve an equitable and sustainable future.
Health Determinants, Applications, and Methods: A Systematic Literature Review on the Relationships Between the Urban Transport of People and Health
Authors: Barros dos Santos Júlia , Lima Josiane Palma
Published: May 2023

This study seeks to contextualize the literature related to the urban transport of people and health. The methodology consisted of a systematic literature review, considering papers published between 2016 and 2021. Some 438 articles were selected for the initial analysis. It was observed that the most recurrent themes were analyses on transportation accessibility and health, and the impacts of active transportation and the built environment on health. Some 173 articles on travel behavior impacts were thoroughly analyzed. The most commonly evaluated health determinants were level of physical activity and obesity. Some studies applied standard questionnaires for health self-assessments. The analyses showed that mental/psychological well-being can have multiple dimensions. Most studies evaluated health determinants using statistical tools, specifically regression models and structural equation models. Health impact assessment was also applied recurrently in the analyzed articles. This study presents theoretical and practical implications, contributing to the state-of-the-art by theoretically deepening understandings of the relationships between transport and health. We also highlighted health aspects, methods, and data collection instruments that could be used in future studies. A better understanding of these relationships can also aid in developing public transportation strategies and policies that help move people and promote social-economic development, while also positively affecting individual physical and mental well-being.

Authors: So Sang-Pil , Kwak Jae-Man , Lee Jun-Bum , Ben Hui , Alsaqri Hood , Kim Keun Ho , Koh Kyoung Hwan , Jeon In-Ho
Published: May 2023

Background:

Arthroscopic osteocapsular arthroplasty (OCA) achieves significant medium-term outcomes in patients with primary elbow osteoarthritis (OA); however, outcomes after revision arthroscopic OCA are not well known.

Purpose:

To assess clinical outcomes after revision arthroscopic OCA as compared with those after primary surgery in patients with OA.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Patients who underwent arthroscopic OCA attributed to primary elbow OA between January 2010 and July 2020 were enrolled. Range of motion (ROM), visual analog scale (VAS) pain score, and Mayo Elbow Performance Score (MEPS) were assessed. Operation time and complications were assessed by chart review. Clinical outcomes between the primary and revision surgery groups were compared, and subgroup analysis for radiologically severe OA was performed.

Results:

Data from 61 patients were analyzed (primary, n = 53; revision, n = 8). The mean ± SD age was 56.3 ± 8.5 and 54.3 ± 8.9 years in the primary and revision groups, respectively. The primary group had significantly better ROM arcs preoperatively (89.9°± 20.3° vs 71.3°± 22.3°; P = .021) and postoperatively (112.4°± 17.1° vs 96.9°± 16.5°; P = .019) than the revision group; however, the degree of improvement was comparable ( P = .445). Postoperative VAS pain score ( P = .164) and MEPS ( P = .581) were comparable between the groups, as were the degrees of improvement in VAS pain score ( P = .691) and MEPS ( P = .604). The revision group required a significantly longer operative time than the primary group ( P = .004) and had a nonsignificant higher complication rate ( P = .065). Subgroup analysis showed that radiologically severe cases in the primary group had significantly better preoperative ( P = .010) and postoperative ( P = .030) ROM arcs than the revision group and a comparable postoperative VAS pain score ( P = .155) and MEPS ( P = .658).

Conclusion:

Revision arthroscopic OCA is a favorable treatment option for primary elbow OA with recurrent symptoms. Postoperative ROM arc was worse after revision surgery as compared with primary surgery; however, the degree of improvement was comparable. Postoperative VAS pain score and MEPS were comparable with primary surgery.
Extracorporeal Life Support in Adult Burn Care: A Systematic Review
Authors: Capoccia Massimo , Maybauer Dirk M , Brewer Joseph M , Maybauer Marc O
Published: May 2023

We sought to review the role of extracorporeal membrane oxygenation (ECMO) for the management of burn and smoke inhalation injury in the adult patient population. Therefore, we conducted a systematic search of the literature according to specific combination of key words to ascertain the effectiveness of this support strategy. A total of 26 articles were filtered out of 269 and considered suitable for this study. The PICOS approach and PRISMA flow chart were followed for the purposes of our review. Although there is growing evidence supporting the role of ECMO as an option for burn injury in the adult patient population, this strategy should be considered if a likely successful outcome is expected.
Estimation of cohesive zone model parameters for glass/Elium composites with different processing temperature
Authors: Han Ning , Fan Longxin , Zhang Yi
Published: May 2023

Important estimates were made of the cohesive zone mode (CZM) characteristics used to predict the fracture of Elium composites processed at various temperatures in this study. First, tests for the end notched flexure (ENF) and double cantilever beam (DCB) on composites processed at different temperatures (24°C, 50°C, and 80°C) were performed. Based on the experimental results, the numerical models of damage evolution were developed. And six pairs of cohesive parameters (cohesive strength and cohesive stiffness) to the specified fracture energy release rates were obtained. Then, a Tsai approach was developed to predict the cohesive strength of the Elium composite with various process temperatures based on the obtained parameters. In order to predict the delamination behavior of the Elium composite, the obtained cohesive parameters were then used to a numerical model of short beam shear (SBS). The peak force of the simulations was discovered to be consistent with the outcomes of the tests. The findings served as a reference for damage assessments of Elium composites processed at various temperatures.
To sanction or not to sanction: Public attitudes on sanctioning human rights violations
Authors: Zarpli Omer
Published: May 2023

Public opinion is central to understanding when states enforce human rights abroad. Yet we do not have firm evidence regarding why individuals demand government action in some cases of human rights violations, but not others. I argue that economic interests and shared identity play important roles. I employ a pre-registered survey experiment in Turkey measuring the extent to which individuals support sanctioning China for its repressive policies against the minority Uyghur population. Results provide partial support for my hypotheses. The findings have implications for the question of international human rights enforcement.
Engaging Disability Theory in Planning Practice

Published: May 2023

In this commentary, we suggest that disability in planning practice is widely under-theorized. Planners must respond to normalized inattention to disability in the planning field and can begin doing so by engaging disability theory in practice. Five disability perspectives are discussed with a view to providing planners with a disability theory toolkit: (1) the medical, (2) social, and (3) biopsychosocial models; (4) a neoliberal viewpoint; and (5) a critical ableist studies lens. We encourage planners to embrace disability theory and the complexity of disability experiences, and to work toward unsettling the normalcy of disabled people’s exclusion in planned environments.
It’s Not Our Way: Navigating the Principle of Dual Relationships as a First Nation Practitioner
Authors: McDougall Tanya Dawn
Published: May 2023

First Nations and Eurocentric approaches in the field of psychology and mental health are rooted in different worldviews which creates incongruencies as to what may be deemed as effective standards of practice. This autoethnography describes the experience of a school psychology intern navigating through practice particularly as it pertains to the principle of dual relationships. With a first-person perspective the journey of exploration into this matter brings together the research found in academia and the guidelines formally set as well as the beliefs and values of local community members which were brought forth through a series of interviews and conversations. There are three main themes which arose that are highlighted and they are the embodiment of a spiritual orientation, substantiation of trust and integrity, and obligation to community. These themes explicate the differences in and implications for practice when working with First Nations people, particularly in remote spiritually connected communities. The practice of psychology in and with First Nation people needs to be rooted in their beliefs, values, and customs to be effective, to reflect the experience of Indigenous ways of helping, and to decolonize approaches in the field of psychology.

Intimate partner problems (IPP)—which include divorce, breakups, arguments, jealousy, conflict, discord, and violence—have been robust precipitating factors associated with an increased risk for suicidal thoughts and behaviors. Although research on suicide related to IPP is growing, efforts to explore the circumstances surrounding suicidality among female victims struggling with IPP remain insufficient. To address this gap, this exploratory study sought to understand the circumstances surrounding female IPP-related suicide in the United States. We conducted a secondary analysis of data from the U.S. National Violent Death Reporting System (NVDRS, 2003–2019) which includes 43 states, the District of Columbia, and Puerto Rico. Of the final analytical sample of 58,545 female suicide cases in the United States, we delineated IPP-included suicide cases (13,496, 23.1%) and non-IPP-included suicide cases (45,049, 76.9%). Two-sided Pearson chi-square tests and standardized difference (SD) tests identified significant differences in the surrounding circumstances between IPP-included suicide and non-IPP-included suicide. IPP-included female suicide was more common among younger women, those involved in an intimate relationship, and women who were pregnant or postpartum ( p < .001; SD > .10). IPP-included suicide victims were more likely to have experienced depression, substance abuse, and previous interpersonal trauma than non-IPP-included suicide victims ( p < .001; SD > .10). Compared to non-IPP-included suicide, IPP-included suicide was more likely to occur at the victim’s house or apartment during evening and nighttime by firearm or hanging ( p < .001; SD > .10). Our findings also showed that IPP-included suicide victims had previous suicidal thoughts and were more likely to have disclosed their suicidal ideation with others before committing suicide than non-IPP-included suicide victims ( p < .001; SD > .10). Findings identified unique circumstances and characteristics possibly associated with IPP-included female suicide. Our understanding of suicide may be enhanced by exploring the causal pathway behind these relationships.
Analysis of dynamic stall control on a pitching airfoil using dynamic mode decomposition
Authors: Zhong Junwei , Li Jingyin , Liu Huizhong
Published: May 2023

Dynamic mode decomposition (DMD) technology is used to analyze the control of dynamic stall on a pitching S809 airfoil using an off-surface rod. The unsteady flows around the original and the controlled airfoil are simulated by using the SST k-ω turbulence model. With the introduction of the off-surface rod, the hysteresis effect of the dynamic stall process of the original airfoil is considerably reduced, and the clockwise sub-loop of the pitching moment coefficient is eliminated. The improvement of the dynamic stall process is beneficial to the safe and high-efficiency operations of wind turbine. The coherent structure of the unsteady flow fields are decoupled by the DMD method compiled by an in-house code in MATLAB. Results reveal that the hysteresis effect is dominated by mode 2 with a pitching frequency and mode 3 with twice the pitching frequency. The global energy of the two modes is reduced by the off-surface rod, which alleviates the hysteresis effect for the original airfoil.
Enterotoxemia produced by lambda toxin–positive Clostridium perfringens type D in 2 neonatal goat kids

Published: May 2023

Enterotoxemia caused by Clostridium perfringens type D usually affects sheep and goats ≥ 2-wk-old. The main clinical signs and lesions of the disease are produced by the epsilon toxin (ETX) elaborated by this microorganism. However, ETX is produced in the form of a mostly inactive prototoxin that requires protease cleavage for activation. It has traditionally been believed that younger animals are not affected by type D enterotoxemia given the low trypsin activity in the intestinal content associated with the trypsin-inhibitory action of colostrum. Two Nigerian dwarf goat kids, 2- and 3-d-old, with a history of acute diarrhea followed by death, were submitted for postmortem examination and diagnostic workup. Autopsy and histopathology revealed mesocolonic edema, necrosuppurative colitis, and protein-rich pulmonary edema. Alpha toxin and ETX were detected in intestinal content, and C. perfringens type D was isolated from the colon of both animals. The isolates encoded the gene for lambda toxin, a protease that has been shown previously to activate ETX in vitro. Type D enterotoxemia has not been reported previously in neonatal kids, to our knowledge, and we suggest that lambda toxin activated the ETX.
Disparities in Advance Directive Documentation for Rural-Dwelling Persons With Lung Cancer
Authors: Catlett Lauren , Johnson Lee Ann
Published: May 2023

Purpose: Advance directives (AD) are recommended for persons with lung cancer, yet few studies have investigated AD and healthcare power of attorney (HCPOA) documentation for this population in rural regions of the United States. The purpose of this study was to examine demographic and clinical factors associated with AD and HCPOA documentation for persons with lung cancer in rural eastern North Carolina (ENC). Methods: A cross-sectional retrospective chart review was conducted to collect demographic and clinical data from electronic health records from 2017 to 2021 at a tertiary cancer center and regional satellite sites in ENC. Descriptive statistics and Chi-Square Tests of Independence were used for data analysis. Findings: The sample’s mean age was 69.5 years (n = 402, SD = 10.5, range = 28 - 92). Most participants were male (58%) and had a smoking history (93%). Consistent with regional population statistics, 32% of persons were black, and 52% lived in rural counties. Just 18.5% of the sample had a documented AD and 26% had a healthcare power of attorney. Black persons had significantly lower AD and HCPOA ( P < .001) documentation than white persons. Rural-dwellers had significantly lower HCPOA documentation than urban-dwellers ( P = .03). For all other variables, no significant differences were found. Conclusions: These findings suggest that AD and HCPOA documentation are low for persons with lung cancer in ENC, particularly for black persons and rural-dwellers. This disparity highlights the need for enhanced advance care planning (ACP) access to and outreach in the region.
