Introduction: Hospital admission due to fragility hip fracture has increased significantly in recent years. In patients with hip fracture, perioperative pain management is usually with opioids, whose dosage is difficult to adjust and have many side effects, especially in older adults. The purpose of this study was to determine the impact and the advantages of the implementation of the fascia iliaca blockade in older adults with hip fracture due to fragility included in the Orthogeriatric Clinical Care Center of the Fundación Santa Fe de Bogotá and the San José Infantil University Hospital in Bogotá, Colombia. The primary outcome of our study is the incidence of delirium during hospitalization. Methods: A retrospective observational cohort study was conducted. The data was collected from patients older than 65 years treated for a fragility fracture of the hip in two fourth-level hospitals in Bogotá, Colombia from the beginning of 2019 until the end of 2020. Results: A sample of 218 patients was obtained, of which 119 received conventional analgesic management. 99 patients underwent fascia iliaca blockade. No significant difference was found between the use of the block and the development of delirium ( p = 0.442). There was a higher consumption of opioids in the conventional analgesia group compared to the block group (27.61 mg vs 16.34 mg, respectively, p = 0.003), longer duration of the surgical procedure (90.84 vs 81.08 min, respectively, p = 0.030) and longer hospital stay (6.06 vs 5.41 days, respectively, p = 0.641). Conclusions: While this study found no significant difference in the incidence of delirium, fascia iliaca blockade was associated with significant reductions in opioid consumption and shorter procedural times. These findings suggest that fascia iliaca blockade may improve pain management efficiency in older adults with hip fractures.
Person-Mysticism: The Heart of Christian Spirituality
Authors: Karuvelil George
Published: January 2025

A twofold sensitivity characterizes Christianity. One is sensitivity to its inner core and the other is sensitivity to its surrounding culture in which it lives and communicates its message. The inner core is the person of Jesus Christ whom his followers experienced as utterly human and completely divine. This is the heart of Christian spirituality. It found its creedal expression in terms of one person having two natures. Although the different creedal statements responded to various Christological controversies and remained faithful to its inner core, neither understanding nor communicating one person having two natures has been easy. Matters came to a head with the anthropocentric turn of the modern period. Friedrich Schleiermacher showed his sensitivity to the changed culture, only to be castigated by Karl Barth for not being sensitive to the inner core. This article argues that studies in nature-mysticism found in the contemporary world enable us to understand the ancient metaphysical terminology of one-person two-natures and also maintain the twofold sensitivity. I do this by using the category of “person-mysticism.” “Person-mysticism” is about encountering God in another human person, understood as an extension of “nature-mysticism” that involves encountering the divine in nature.
Prayer, Purpose, and Expanding the Table of Possibility in Theological Education
Authors: Walton Jonathan Lee
Published: January 2025

Dr. Jonathan Lee Walton's inaugural address as President of Princeton Theological Seminary presents a critical engagement with the narratives of religious decline, particularly in the context of American Protestantism. Challenging the cultural and class-based origins of “mainline” Protestant identity, Walton critiques the limitations of meritocratic structures that dominate both religious and societal frameworks. Drawing from the parable of the banquet in Luke 14, Walton argues for a reimagined theological and educational mission—one that expands the “table of possibility” by inviting those marginalized by traditional hierarchies. This address situates Princeton Seminary as a vital force in shaping a more inclusive, accessible theological education. Walton articulates the urgency of bridging the gap between historical privilege and contemporary spiritual hunger, highlighting the Seminary's role in cultivating moral imagination, advancing hybrid and flexible educational models, and addressing global challenges of justice and faith. Through this, he advocates for a Seminary that remains grounded in its mission while boldly adapting to serve a diverse and evolving world. This work contributes to ongoing theological discourse on institutional adaptation, ecclesiastical inclusivity, and the redefinition of religious leadership in the twenty-first century.
Calculative infrastructures of net zero urban governance: A transformative science-based agenda or reductive territorial project?
Authors: Davey Taylor
Published: January 2025

The current emphasis on data-driven urban climate governance, while not a new project, is nevertheless evolving as part of a new calculative politics shaped by a net zero agenda. This urban project is realised via the development of calculative infrastructures that deploy more robust measurement fields through which urban action can be made directly relevant to global climate targets. A key premise is that it is possible to project the global scientific concept of net zero onto the ground as a territorial target, which in turn relies on the technical work of balancing emissions. I argue that this often materialises as a reductive governance project based on the accountability of public actors to new carbon balance sheets, wholly detached from a more systemic transition politics. This critical commentary begins by introducing net zero as an urban agenda and explores how calculative infrastructures offer the means of making a consolidated international agenda actionable as an urban territorial governance project. I examine the urban carbon inventory protocol as the foundation to other calculative work and discuss three subsequent infrastructure projects: reporting frameworks and platforms, scenario planning tools and carbon budgets. This calculative project promises a long-term pathway to decarbonisation but is based on a narrow lens that misjudges the more systemic transformation that must take place. The commentary concludes by considering how (or if) net zero as a political framework could support a more radical transition politics.
Duality of Tourists’ Value Co-Creation Behaviors in the Sharing Economy: Longitudinal Insight from Airbnb via Social Media Analytics
Authors: Wang Rui , Hao Jin-Xing
Published: January 2025

The intricate relationships between tourists’ value co-creation behaviors and value perception in the sharing economy have attracted increasing attention from researchers and practitioners. Unlike previous studies that focused on such relationships at a particular time point, this study sheds light on the dynamics of tourists’ value co-creation behaviors and employs social media analytics to reveal their longitudinal role in value perception. Our empirical specifications reveal the long-run one-way causality of such relationships, disclose their inverted U-shaped relationships over time, and quantify the boundary thresholds at which value co-creation transforms into value co-destruction. These findings also uncover a significant interaction effect across two value co-creation behavior dimensions, that is, participation behaviors and citizenship behaviors. This study enriches our knowledge of the duality of tourists’ value co-creation behaviors, and offers insights into how to leverage the boundary thresholds of value co-creation behaviors to formulate customized tourism marketing strategies in the sharing economy.
Brokering and (Re)membering: Immigrant Children’s In/visible Work of Implementing a Two-Way Dual Language Bilingual Education Program and Educators’ Perceptions
Authors: Becker Mariana Lima , Oliveira Gabrielle
Published: January 2025

Background:

Guidelines for the successful implementation of two-way dual language bilingual education (DLBE) programs foreground the role of program leadership, hiring and preparing culturally and linguistically competent teachers, family involvement, and the alignment between curriculum, assessments, and instruction in both languages. Absent in this framing for program implementation and success are the voices, lived experiences, and everyday contributions of immigrant children who take part in such programs.

Focus:

Grounded in a critical orientation to immigrant childhoods, this article explores how a group of 70 Brazilian immigrant children (ages 5–7) navigated a new two-way DLBE program (Portuguese–English) in the U.S. state of Massachusetts. By looking into how the children interacted and participated in class, we foreground how they contributed to the maintenance of the program as two-way DLBE implementers.

Research Design:

This article draws from a larger ethnographic research study conducted over three school calendar years (2018–2021). It leverages field notes from weekly classroom visits in the two-way DLBE program and semistructured interviews with 18 school staff members. Data sources were coded using thematic analysis, with attention to how immigrant children’s actions contributed to teachers’ instruction and how these contributions were perceived by educators and other staff members.

Findings/Conclusions:

Brazilian immigrant students in K–2 classrooms contributed daily to the implementation of their two-way DLBE program through language brokering across Portuguese- and English-medium classrooms, facilitating peer participation in class, and invoking transborder memories in ways that complexified the ongoing classroom discourse. However, two-way DLBE educators and other staff members characterized newcomer students from Brazil as bringing key linguistic assets to school while positioning the children born in Brazilian immigrant households in the United States as “caught in-between” languages and undermining the program implementation. These findings suggest the need for a holistic focus on immigrant childhoods in two-way DLBE programming.

Authors: Xie Zong-Sheng , Hao Xin , Liu Guo-Huai , Zheng Hang , Yi Chu-Shan , Wang Zhao-Dong
Published: January 2025

The introduction of the electromagnetic oscillation (EMO) process has significantly improved the casting defects of the superalloy turbine guide castings, and the effect of EMO process on the defects, grain size, and tensile properties in superalloy turbine guide castings is also investigated. The results show that the EMO process ensures excellent mold filling of K477 and K536 superalloy turbine guide castings at lower preheating temperatures. The surface quality of K477 superalloy guide castings is significantly improved by EMO process, exhibiting almost no surface macroscopic shrinkage. Meanwhile, under the EMO process, the grain size of K536 superalloy turbine guide blades is reduced by over 46.75%, and the distribution of carbides and solid solution elements within the grains are improved, producing uniform, fine equiaxed grains across the blades. The elongations at room and high temperatures are increased by 24.78% and 46.4%, respectively.
Effect of different modified semisolid processes on hardness and wear behavior of Al-0.9 Mg-0.7 Si-0.2 Zn alloy
Authors: Karamouz Mostafa , Jesmani Seyed Mohammad
Published: January 2025

This research aims to study the effect of three different semi-solid processes on the microstructure, hardness, and wear behavior of Al-0.9 Mg-0.7 Si-0.2 Zn alloy. Conventional strain induced melt activation (SIMA), SIMA plus annealing, and a new two-stage SIMA (TSSIMA) were conducted and their effects were evaluated. The results showed that TSSIMA led to the most appropriate microstructure owing to grain refinement, the removal of the eutectic microstructure, uniform distribution of the precipitates, and thin grain boundaries. These, in turn led to the highest hardness and least wear weight loss in this sample. Moreover, it was found that the softening effect of annealing in process 2 (SIMA + annealing) counteracted the positive effect of Conventional SIMA process.
Investigations of surface characteristics on AA5083 alloy with dual treatment
Authors: Sarukasan D , Thirumavalavan K
Published: January 2025

This study compares the mechanical, tribological, and corrosion characteristics of four different substrates: untreated (UNT), untreated substrate then coating (UNTC), LSP-treated (LSPT), and LSP-treated then coating (LSPTC). This study explains how the dual surface treatment LSP and W_HVOF based molybdenum coating on the mechanical properties and corrosion resistance of AA5083 aluminum alloy. Nanoindentation tests revealed significant improvements in hardness and Young's modulus for LSPTC specimens. Surface roughness analysis showed that LSPTC specimen increased roughness, potentially to enhancing coating bonding. Scratch and wear tests demonstrated superior wear resistance for LSPTC specimens due to their higher hardness and reduced friction. Contact angle measurements indicated that LSPTC specimen made the surfaces more hydrophobic. Electrochemical corrosion analysis revealed that LSPTC specimens exhibited the lowest corrosion rates, outperforming untreated and LSPT specimens. FESEM and XRD analyses confirmed the positive effects of LSPTC specimen on microstructure and residual stress, contributing to the improved mechanical properties and corrosion resistance.

Authors: Larsson Alexandra C. , Palstam Annie , Ashman Kröönström Linda , Sunnerhagen Katharina S. , Persson Hanna C.
Published: January 2025

Objective

To identify factors, present at 3 months after COVID-19 that are associated with the level of functioning 1 year after hospitalization.

Design

Multicenter prospective observational study.

Setting

Region Västra Götaland Sweden.

Participants

Patients ≥ 18 years of age who were followed regarding body functions and activities 3 months and 1 year after discharge from a hospitalization for COVID-19.

Main measures

Patient-reported outcome measures at 3 months and 1 year, a clinical follow-up at 1 year, and clinical information retrieved from medical charts.

Results

In total 169 participants were included in the analysis, including 113 males (67%). The mean patient age was 66 (standard deviation (SD) 13, range 21–95). One year after hospitalization, 50 (34%) participants were under the normative value for forced vital capacity and 57 (39%) were under normative value for forced expiratory volume in 1 second. The mean walking distance was 441 m (SD 118 m) in the 6-minute walking test, and 62 (40%) patients reported mobility problems. Older age, female sex, and more self-reported symptoms of physical fatigue were significantly associated with lower levels of functioning 1 year after COVID-19. The initial severity of COVID-19 did not significantly influence functioning at 1 year.

Conclusion

Previously hospitalized individuals with respiratory difficulties 1 year after COVID-19 may present acceptable lung function on spirometry but be close to their maximal functional performance. The findings highlight the need for in-depth assessments to identify rehabilitation needs.

Spontaneous intracerebral hemorrhage(ICH) represents a life-threatening form of stroke, marked by its impact on survival and quality of life. ICH can be categorized from monogenic disorders linked to causal germline variants in ICH-related genes to complex sporadic cases, highlighting the interaction among lifestyle factors, environmental influences, and genetic components in determining risk. Among sporadic ICH, the influence of these factors varies across ICH subtypes, evidenced by heritability rates of up to 73% for lobar ICH versus 34% for non-lobar ICH. This review presents an outline of the genetic landscape of ICH, covering both monogenic and sporadic forms. It highlights associations between ICH risk and genetic variants, including rare and common variants in genes such as COL4A1, COL4A2, APOE, ACE, MTHFR, and PMF1. However, replication has been constrained, and most findings originate from single-candidate gene studies, largely due to ancestry heterogeneity, small sample sizes, and scarce subtype-specific data. To bridge this gap, collaborative efforts like the International Stroke Genetic Consortium have been established. Additionally, the review discusses the emerging role of polygenic risk scores, Mendelian randomization, and the potential of genetic and omics research to elucidate causal pathobiology. Such insights could lead to preventive measures and personalized ICH treatment strategies.
Glutamine metabolism is systemically different between primary and induced pluripotent stem cell-derived brain microvascular endothelial cells

Published: January 2025

Human primary (hpBMEC) and induced pluripotent stem cell (iPSC)-derived brain microvascular endothelial-like cells (hiBMEC) are interchangeably used in blood-brain barrier models to study neurological diseases and drug delivery. Both hpBMEC and hiBMEC use glutamine as a source of carbon and nitrogen to produce metabolites and build proteins essential to cell function and communication. We used metabolomic, transcriptomic, and computational methods to examine how hpBMEC and hiBMEC metabolize glutamine, which may impact their utility in modeling the blood-brain barrier. We found that glutamine metabolism was systemically different between the two cell types. hpBMEC had a higher metabolic rate and produced more glutamate and GABA, while hiBMEC rerouted glutamine to produce more glutathione, fatty acids, and asparagine. Higher glutathione production in hiBMEC correlated with higher oxidative stress compared to hpBMEC. α-ketoglutarate (α-KG) supplementation increased glutamate secretion from hiBMEC to match that of hpBMEC; however, α-KG also decreased hiBMEC glycolytic rate. These fundamental metabolic differences between BMEC types may impact in vitro blood-brain barrier model function, particularly communication between BMEC and surrounding cells, and emphasize the importance of evaluating the metabolic impacts of iPSC-derived cells in disease models.
Resilience and Recovery in the Dry Chaco: Ecological Knowledge Encoded in Forager Wildfire Narratives
Authors: Sugiyama Michelle Scalise , Mendoza Marcela , Carpio María Belén
Published: January 2025

The tropical forests, shrublands, and savannas of the South American Dry Chaco are fire-prone ecosystems. Humans have occupied this region for thousands of years, raising the question of how they coped with this recurrent problem. On this point, Indigenous oral traditions are known to encode a broad range of local ecological knowledge and to be capable of preserving this knowledge for centuries. Although the traditions of the Chaco's earliest human occupants are unknown, the story corpora of recent Chaco hunter-gatherer populations have been well documented by anthropologists. Accordingly, we searched these corpora for catastrophic wildfire narratives, which we then coded for the presence of specific types of information relevant to coping with conflagration. We predicted that these stories would contain information about conditions that cause or increase the likelihood of conflagration, fire behavior and effects, human survival strategies, and plant and animal recovery. We parsed this information into 11 distinct content themes: Ambient Conditions, Cause, Direction/Speed, Duration/Frequency, Intensity, Severity, Spread, Coping Strategies, Cues, Animals, and Plants. Results indicate that wildfire stories occur cross-culturally in the Dry Chaco, and reliably encode useful information about past local fire regimes. In so doing, these narratives provide a heretofore untapped source of longitudinal fire ecology data, and attest to the importance of including Indigenous observations in global scientific inquiry.
Geographical education III: Changing climate, changing geographies, changing geographical education?
Authors: Puttick Steve
Published: January 2025

This third progress report critically examines the shifting role of climate change in geographical education: from a peripheral concern to an urgent and defining priority. Climate change now occupies substantial space across research, practice and curriculum, however, this transformation unfolds amid ongoing ‘lag’ between public discourse, research evidence, and curriculum development. Highlighting tensions across urgency and complexity, global and local scales, and representation and justice, the report concludes with a call for building geographical education futures that are creative, generous, hopeful, diverse and robust enough to meet the challenges of climate change.
Posterolateral Corner Reconstruction: A Systematic Review and Meta-analysis of Biomechanical Studies
Authors: Zielinski Kyle P. , Wieland Mark D. , Sequeira Sean B. , Gould Heath P. , Dreese James C.
Published: January 2025

Background:

Surgical reconstruction is the standard treatment for injuries to the posterolateral corner (PLC) of the knee and can be performed using either a fibular-based or combined tibiofibular-based technique. Although some comparative studies have been performed, there is no consensus regarding the reconstructive approach that confers optimal biomechanical properties of the PLC.

Purpose:

To perform a systematic review and meta-analysis to evaluate the biomechanical properties of the knee after PLC reconstruction with fibular-based and tibiofibular-based techniques.

Study Design:

Meta-analysis; Level of evidence, 4.

Methods:

A systematic review was performed by searching the PubMed, Cochrane Library, and Embase databases using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to identify studies that analyzed the biomechanical properties of PLC reconstruction techniques. Evaluated outcomes included varus laxity and external rotation laxity. The pooled biomechanical data were analyzed by random-effects models and heterogeneity was assessed using the I2 statistic.

Results:

Eleven studies met the inclusion criteria; 74 cadaveric specimens were included. Seven studies (54 specimens) evaluated the fibular-based Larson reconstruction technique, 3 studies (22 specimens) evaluated a modified fibular-based Larson reconstruction, and 1 study (7 specimens) evaluated the fibular-based Arciero reconstruction. Five studies (45 specimens) evaluated the tibiofibular-based LaPrade reconstruction technique and 2 studies (20 specimens) evaluated a modified LaPrade reconstruction. Data were pooled for fibular-based reconstructions (Larson, modified Larson, and Arciero) and tibiofibular-based reconstructions (LaPrade, modified LaPrade). Pooled analysis revealed no significant difference in varus laxity and external rotation laxity between fibular and tibiofibular reconstructions at 0°, 30°, 60°, and 90° of flexion (all P > .05).

Conclusion:

No difference in varus laxity and external rotation laxity was observed between fibular-based and tibiofibular-based techniques for PLC reconstruction. Moreover, there was no difference in varus laxity and external rotation laxity observed between the Larson, modified Larson, and LaPrade reconstructions. These results suggest that biomechanical stability after fibular- and tibiofibular-based PLC reconstructions is similar. Further clinical investigation is warranted to validate these cadaveric findings.
The Presence of a Trochlear Bump and Patella Alta May Predict the Risk of Recurrent Instability After Isolated Medial Patellofemoral Ligament Reconstruction: A Systematic Review and Meta-analysis
Authors: Dandu Navya , Elias Tristan J. , Hevesi Mario , Trasolini Nicholas A. , Zavras Athan G. , Haneberg Erik , Yanke Adam B.
Published: January 2025

Background:

Medial patellofemoral ligament reconstruction (MPFLR) is an excellent surgical option for patients with recurrent patellar instability. This technique has demonstrated significant improvements in patient-reported outcomes, high rates of return to sport, and low rates of failure. However, there is debate regarding the use of isolated MPFLR in the setting of concomitant pathoanatomic features such as patella alta, trochlear dysplasia, or a lateralized tibial tubercle.

Purpose:

To estimate the overall relative effect sizes as well as strength of evidence supporting described risk factors for recurrent instability after isolated MPFLR.

Study Design:

Systematic review and meta-analysis.

Methods:

A systematic review was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The PubMed, Embase, Cochrane, and Ovid/MEDLINE databases were queried. Clinical studies for outcomes of isolated MPFLR reporting recurrent instability and associated risk factors were included. Data for each risk factor analyzed by at least 2 studies were extracted, and the heterogeneity of studies was determined by I2 value. For variables evaluated in studies determined to have fair homogeneity, defined as I2 <25%, DerSimonian-Laird random-effects models were generated and effect sizes were represented as mean differences or odds ratios.

Results:

Nine studies examining risk for recurrent instability after isolated MPFLR were identified, with 5 overlapping risk factors with low heterogeneity between studies: age, sex, tibial tubercle to trochlear groove (TT-TG) distance, Caton-Deschamps Index (CDI), and trochlear dysplasia. There was strong evidence to support the risk of recurrent instability associated with CDI >1.3 (OR, 2.72; P = .02) and dysplasia with a trochlear bump (DeJour type B or D; OR, 3.28; P <.001). Age, sex, and TT-TG distance did not cause an increased risk of recurrent instability with currently available aggregate data.

Conclusion:

There are signs of increased risk of failure of isolated MPFLR in the setting of DeJour type B and D trochlear dysplasia and patella alta (CDI, >1.3). Currently available data suggest that age, sex, and TT-TG distance do not cause a higher risk of recurrence for patients undergoing isolated MPFLR.

Published: January 2025

Background:

Loss of motion and arthrofibrosis after anterior cruciate ligament (ACL) reconstruction (ACLR) can be devastating complications for athletes. The cellular and molecular pathogenesis of arthrofibrosis is poorly understood, limiting prevention and treatment options. Synovial inflammation may contribute to post-ACLR arthrofibrosis.

Hypothesis:

Higher synovial immune cell infiltration and inflammatory/catabolic gene expression patterns at the time of ACLR would correlate with poorer motion-related outcomes.

Study Design:

Case series; Level of evidence, 4.

Methods:

Patients aged 10 to 18 years undergoing primary ACLR were enrolled in a prospective pilot study, and synovial tissue biopsy specimens were obtained during ACLR. Flow cytometry and single-cell RNA sequencing explored synovial cell types/frequencies and gene expression. Principal component analysis was performed, followed by clustering which grouped patients into distinct immunophenotypes based on their synovial cell composition. Clinical follow-up data with knee range of motion (ROM), need for lysis of adhesions, and patient-reported outcome measures were collected and compared between immunophenotypes.

Results:

Enrolled patients (n = 17) underwent ACLR at a median of 37 days after injury. Analysis revealed 3 distinct immunophenotypes. Type 1 consisted of patients with the longest time between injury and surgery and the lowest hematopoietic and T-cell infiltration. Types 2 and 3 had similar times between injury and surgery; type 2 had intermediate while type 3 had the highest hematopoietic and T-cell percentages. Type 3 was associated with worse ROM at 2 and 6 weeks postoperatively; T-cell prevalence and ROM were inversely correlated at those time points. The only patient requiring lysis of adhesions for arthrofibrosis had a type 3 immunophenotype.

Conclusion:

Synovial immune infiltration after ACL injury shows variability between patients that clusters into 3 immunophenotypes correlating with early ROM and the risk of arthrofibrosis. T-cell recruitment and infiltration were the strongest factors correlated with ROM outcomes and present an exciting venue for future research on post-ACLR arthrofibrosis.
Validation de L’échelle Unidimensionnelle D’Estime de Soi de Ducher (ESD): Validation of Ducher's Unidimensional Self-Esteem Scale (SES)
Authors: de Chazeron I. , Ducher J.-L. , Renoux M. , Brousse G. , Llorca P.-M.
Published: January 2025

Résumé

Objectif

Même si l’estime de soi est un concept relativement récent, développé d’abord dans le domaine de la psychologie sociale, elle a pris de plus en plus d’importance en psychiatrie, en particulier en tant que critères diagnostiques. Cependant, elle est peu évaluée en pratique clinique. L’absence d’instrument en permettant une évaluation globale aisée en est peut-être la raison. Il s’agit donc de valider en langue francophone une échelle brève, unidimensionnelle, d’Estime de Soi (ESD), autorisant éventuellement un suivi évolutif par autocorrection.

Méthode

L’étude a porté sur 106 patients présentant différents troubles psychiatriques, à l’exception de trouble psychotique, stabilisés ou de niveau de gravité variable. La création de l’outil initial comprenait 10 items. Il a été soumis à la sélection d’items suivie d’une analyse factorielle exploratoire. La corrélation entre les items ainsi que la mesure de la cohérence et de la validité convergente ont été ensuite réalisées.

Résultats

L’évaluation de l’acceptabilité et de la distribution des résultats a conduit à la sélection de 6 items. L’analyse factorielle exploratoire révèle une dimension unique et une bonne fiabilité (Tucker-Lewis Index =0.89). Aucun item n’affiche des corrélations avec un score total inférieur à 0.50 et la notion du construit est cohérente. On note également une bonne consistance interne ce qui confirme que la version ESD à 6 items est optimale.

Conclusion

Cette nouvelle échelle validée pourra permettre aux thérapeutes d’investiguer de façon plus précise la notion d’estime de soi en clinique ou dans un cadre de recherche.

Published: January 2025

The Canadian Association of Radiologists (CAR) Endometriosis Working Group was tasked with providing guidance and benchmarks to ensure the quality of technique and interpretation for advanced imaging modalities associated with diagnosing endometriosis. Advanced pelvic ultrasound is essential in diagnosing and mapping pelvic endometriosis, but pelvic MRI serves as an excellent imaging tool in instances where access to advanced ultrasound is limited, or an alternative imaging modality is required. Despite the known utility of MRI for endometriosis, there is no consensus on imaging protocol and patient preparation in Canada. To improve patient care and support excellence in imaging, the Working Group has developed recommendations for the use of pelvic MRI to assess for endometriosis with an aim to standardize MRI technique for use in both community and academic practices across Canada. The guidelines provide recommendations regarding imaging technique and patient preparation for pelvic MRI, along with suggestions for structured reporting of pelvic MRI for endometriosis.
“That Came Back to Haunt Me”: Violence Against Women Survivors’ Concerns About Police Use of Body-Worn Cameras
Authors: Couture-Carron Amanda , Saulnier Alana
Published: January 2025

Despite the substantial contact police have with survivors of violence against women, empirical accounts of survivors’ perceptions of police use of body-worn cameras (BWCs) are limited. This study examines survivors’ concerns with BWCs. We present qualitative data from semi-structured interviews with 33 survivors of intimate partner abuse and sexual assault. While the majority (79%, n = 26) of the women in this study support police use of BWCs, most (90%, n = 30) still express concerns with the technology. Survivors’ concerns fell into three main areas: fear of BWCs capturing trauma responses that could be used against survivors, BWCs decreasing survivor comfort and reporting, and BWCs revictimizing survivors and contributing to survivors’ loss of control. The findings reveal concerns that police can work to address to avoid survivor–police relations being deteriorated by police use of BWCs.
The Combined Effects of Adverse and Positive Childhood Experiences on Adolescent Bullying Victimization and Perpetration
Authors: Dixon Everett Hannah , Jones Melissa S. , Hoffmann John P.
Published: January 2025

Bullying is a persistent social and behavioral problem in the United States. Bullying victimization and perpetration are linked to a host of negative physical, social, and emotional outcomes. Research suggests that a key risk factor for bullying behaviors is adverse childhood experiences (ACEs). On the other hand, positive childhood experiences (PCEs) may counter some of the negative effects of ACEs. This study (a) assesses the independent effects of ACEs and PCEs on adolescent bullying victimization and perpetration, and (b) examines whether ACEs and PCEs interact to affect bullying victimization and perpetration.We use data from the 2020 to 2021 National Survey of Children’s Health, a nationally representative survey of children ages 0 to 17 in the United States. The analytic sample was limited to children who were 6 years old or older at the time of the survey ( N = 60,809). Using caregiver reports of bullying victimization and perpetration, we created a cumulative ACEs scale comprised of 10 items and a cumulative PCEs scale comprised of eight measures. We then estimated a set of logistic regression models to predict bullying behaviors. The results showed that ACEs are associated with a higher likelihood of both bullying victimization and perpetration. Although PCEs have a slight mitigating effect, ACEs and PCEs interact such that even in the presence of PCEs, children with many ACEs still have a higher likelihood of both bullying victimization and perpetration. This highlights the considerable impact of ACEs on bullying behaviors. These findings suggest that enhancing ACE-aware care and ACE prevention is important because even promoting PCEs is unlikely to decrease bullying levels on their own.
Optimizing laser spot size for improved structural integrity in additively manufactured copper alloy components
Authors: Saravana Kumar M , Jeyaprakash N , Yang Che-Hua
Published: January 2025

Laser powder bed fusion (LPBF) offers significant advantages for printing Cu–Cr–Zr alloy, such as thermal stability, design flexibility, and impressive strength. However, surface defects and pore formation, often caused by using unoptimized parameters, can impact the efficiency of complex geometries and parts. The primary goal of this research is to minimize these defects by optimizing key processing parameters. In this research, laser spot size (100, 200, and 300 µm), scan speed (450, 650, and 850 mm/s) and layer thickness (30, 60, and 90 µm) were examined to achieve a defect-free copper alloy part. Nanohardness, porosity and surface roughness were considered as the response variables. Analysis of variance (ANOVA) coupled with complex proportional assessment (COPRAS) approach was performed to identify the optimal parameter settings. While adopting the optimal parameter settings, there was a 69.9% reduction in the surface roughness, 98.5% reduction in the porosity and 91.9% reduction in the nanohardness of the printed Cu alloy parts. Additionally, the effects of different combinations of input parameters on surface roughness and the mechanism that lies behind the porosity formation were demonstrated. The implementation of 100 µm spot diameter, 30 µm layer thickness and 650 mm/s scan speed resulted in defect-free Cu alloy parts with reduced porosity of 0.13%, minimum surface roughness of 10.37 µm, and maximum nanohardness of 6.2 GPa, according to confirmation experiments conducted for the ideal and initial settings. Moreover, the obtained result from the confirmation experiments has a greater concurrence with the COPRAS approach.

Climate change has a direct impact on the seasons. These changes can significantly impact communities living in close interdependence with their territories, such as Indigenous Peoples. Furthermore, these impacts are often entangled and reinforced by other ecological and social processes that affect how communities organise themselves. Drawing from ethnographic research complemented by the life story of a Pewenche woman, this article analyses the intertwined effects of climate change and state policy on the knowledge and seasonality of the Pewenche People in the Southern Andes, Chile. As a result of extensive exploitation of the territory, the implementation of development programmes and the current impacts of climate change, the Pewenche are facing numerous changes that directly affect the rhythms and frequencies that have historically shaped the seasons while impacting their activities, livelihoods and traditions. Their transhumance cycles have been affected, and their economies and calendars must adjust to the new rhythms imposed by state policy. The multiple seasonalities that come into play affect how the Pewenche identify themselves, construct meanings about social life, and position themselves vis-à-vis the state. A reflection on what it means to be Pewenche today has been opened. The bewilderment calls for action and policies that recognise the value of traditional ecological knowledge in fostering resilience and maintaining cultural identity, can respond to the changes and, at the same time, maintain the balance.
Right to paid annual leave: The Cour de cassation recognized the direct horizontal effect of Article 31(2) of the EU Charter and strengthened the protection of employees’ rights Case note to Cases n° 22-17.340 Société Transdev, n° 22-17.638M.

The French judicial court has operated an important reversal of its case law with three judgments of the 13 of September 2023. For the first time, the Cour de cassation decided to apply Article 31 (2) of the Charter of Fundamental Rights, enshrining the right to paid annual leave, in a horizontal litigation by following the Bauer judgment of the Court of Justice. But this was not the only change that the Cour de cassation made with its rulings of 2023. In fact, it adopted an extensive conception of the right to annual leave by following again the case law of the Court of Justice. This reversal of the French case law was so important that it provoked a legislative amendment of the problematic provisions of the French Labour Code. A trialogue between the Court of Justice, the Cour de cassation and the French legislature permitted thus a better protection of this fundamental social right of employees in France. The decision of the Conseil constitutionnel that followed in 2024, which continued to adopt a restrictive approach of the constitutional right to paid leave, illustrated the added-value of Article 31(2) of the Charter and the importance of the three judgments of the Cour de cassation in 2025.
The ethical CPA: Journal of Accountancy letters to the editor
Authors: Saxton Gregory D , Rahaman Abu , Neu Dean , Taylor-Neu Kieran
Published: January 2025

This study uses computerised textual analysis methods to examine 1,769 letters to the editor published in the Journal of Accountancy between 1951 and 2020. Arguing that these letters enunciate an evaluative and expressive stance about issues affecting the profession, we first map the social characters, concepts, and subjects that letter writers talk about. Second, we build on this initial mapping by identifying the discursive communities that are present within the letters and the positioning of ethical words vis-à-vis these communities. Third, we consider the moment(s) in the letter when ethical words are enlisted. The study contributes to our understanding of professional accounting by foregrounding how letter writers articulate their vision of accounting work. The study also demonstrates the usefulness of computerised textual analysis methods for studying historical accounting textual materials.
Incongruent Expectations: A Qualitative Study of the Gendered Experiences of Canadian Young People

While the early mental health of girls and boys is similar, as children age, girls tend to report worse mental health than boys. Explanations for these gendered disparities remain elusive. This study seeks to understand the social context in which mental health experiences are shaped. Utilizing a qualitative, constructivist approach to grounded theory, we conducted virtual semi-structured interviews with young people between ages 11 and 17 years ( n = 20). Our major finding was that girls in particular experience incongruence between expectations about gender equality and everyday experiences of stereotypes, barriers, and discrimination. Girls reported pressures to satisfy multiple gender norms, such as traditional ideals about being feminine (kind and physically attractive) and modern ideas about being high achieving and “smarter than boys.” Findings suggest that young people are unequipped to navigate the incongruence between the expectation that they live in a gender-equal world and their experiences of gender-based constraints, nor do they appear to have the skills to critically identify the structural patterns that undergird their experiences. Explanations for gendered disparities in mental health may be related to the underlying context of discrimination, and both traditional and emerging gendered norms, barriers, and constraints. Finally, we highlight the responsibility of adults to facilitate child development in ways that are responsive to the changing faces of gender discrimination, which readily adapts to social discourse in new and subtle ways.
Nondisclosure and the Impact on Symptom Burden in Muslims With Advanced Cancer: A Review of Five Symptom Assessment Tools
Authors: Tareen Mona
Published: January 2025

Cultural and religious beliefs in certain regions, including many Muslim-majority countries, often lead families to request the withholding of medical information from patients. Despite the availability of validated symptom assessment tools for chronic conditions such as cancer, chronic obstructive pulmonary disease, neurological disorders, heart disease, and renal failure, the effect of nondisclosure on symptom burden remains insufficiently explored. This scoping review examines the role of symptom assessment tools in evaluating the outcomes of nondisclosure in advanced cancer patients, particularly in the United Arab Emirates (UAE). The review assesses five key instruments: the Edmonton Symptom Assessment Scale (ESAS), its revised version (ESAS-r), the Memorial Symptom Assessment Scale (MSAS), the short form (MSAS-SF), and the Palliative Care Outcome Scale (POS). An analysis of the psychometric properties, strengths, and limitations of these tools highlights their utility in understanding symptom burden and psychological well-being. The findings suggest that comprehensive tools like the MSAS provide valuable assessments but require further validation to confirm their effectiveness across diverse clinical and cultural settings. Future research should prioritize adapting these tools for wider application and ensuring their reliability and validity in measuring the impact of nondisclosure on symptom burden across various diagnoses, including both cancer and noncancer conditions.
Exploring the Dynamics of Marital Commitment, Communication Patterns, and Conflict Handling: Insights From Women in Child Marriages

Published: January 2025

This research delves into the intricate dynamics of marital commitment, communication patterns, and conflict handling among women experiencing child marriages in Pakistan. This scientific research employs a quantitative research design and survey-based methodology to investigate the intricate dynamics of marital commitment, communication patterns, and conflict handling among women experiencing child marriages in Pakistan. The study aims to comprehensively explore the interconnections among crucial variables within this specific demographic. A sample of 260 women, aged 16 to 35, with child marriages, was selected using a snowball sampling technique. Inclusion criteria encompassed women married before 18, aged ≤35, married for at least 2 years, and possessing a minimum of primary education. The research employed the Urdu versions of the Social and Emotional Competence Questionnaire (SECQ), Dyadic Adjustment Scale (DAS), Romantic Partner Conflict Scale (RPCS), Communication Patterns Questionnaire: Short Form (CPQ), Dimensions of Commitment Inventory (DCI), and Social Dominance Orientation Scale (SDO). Stepwise regression analyses are employed to unravel the predictive power of marital commitment, communication patterns, conflict handling, and social and emotional competence on marital quality. Results reveal significant insights into the complex relationships within the studied population. The findings highlight the idea of integrating community-based support networks to enhance the effectiveness of counseling interventions. Globally, these insights contribute to a broader understanding of child marriages, offering strategies that can be adapted across cultures to support women in similar situations. By focusing on these new approaches, counselors can help improve the mental health and marital outcomes of women in child marriages, both within Pakistan and internationally.
