Within and Outside the Black-Maghrebi Binary
Authors: Parikh Shreya 
Published: November 2024

Abstract
What does it mean to be both Black and Tunisian, Black and Maghrebi, when the two identities are defined as different from each other, and in opposition with each other, in both North Africa and its diaspora? This article is an annotated conversation with Dr. Maha Abdelhamid, a Tunisian Black activist and scholar who has been crucial to the creation of the Black movement in Tunisia and Tunisian diaspora. This conversation examines the construction and negotiation of Tunisian-Black and Maghrebi-Black identities through Abdelhamid’s experiences of living in and working against racism in both Tunisia and France. It details Abdelhamid’s trajectory in becoming conscious of her Black and African identities, her complex relationship with her Arab identity, her role in building the Black movement in Tunisia after the 2011 revolution, and her arrival in France and experiences of exclusion in both Maghrebi diasporic as well as Black feminist civil society organizations. The interview points to the possible essentialization of Maghrebi and Black as separate identities not only in socio-political discourses that racialize and marginalize these groups, but also among groups challenging Islamophobia or anti-Blackness, leaving those with overlapping identities and racializing experiences outside their scope.

Consider a graph with nonnegative node weight. A vertex subset is called a CDS (connected dominating set) if every other node has at least one neighbor in the subset and the subset induces a connected subgraph. Furthermore, if every other node has at least m neighbors in the subset, then the node subset is called a [Formula: see text]CDS. The minimum-weight [Formula: see text]CDS problem aims at finding a [Formula: see text]CDS with minimum total node weight. In this paper, we present a new polynomial-time approximation algorithm for this problem, which improves previous ratio by a factor of 2/3.

Digital Lyrebirds: Experimental Evidence That Voice-Based Deep Fakes Influence Trust
Authors: Schanke Scott , Burtch Gordon , Ray Gautam 
Published: November 2024

We consider the pairing of audio chatbot technologies with voice-based deep fakes, that is, voice clones, examining the potential of this combination to induce consumer trust. We report on a set of controlled experiments based on the investment game, evaluating how voice cloning and chatbot disclosure jointly affect participants’ trust, reflected by their willingness to play with an autonomous, AI-enabled partner. We observe evidence that voice-based agents garner significantly greater trust from subjects when imbued with a clone of the subject’s voice. Recognizing that these technologies present not only opportunities but also the potential for misuse, we further consider the moderating impact of AI disclosure, a recent regulatory proposal advocated by some policymakers. We find no evidence that AI disclosure attenuates the trust-inducing effect of voice clones. Finally, we explore underlying mechanisms and contextual moderators for the trust-inducing effects, with an eye toward informing future efforts to manage and regulate voice-cloning applications. We find that a voice clone’s effects operate, at least in part, by inducing a perception of homophily and that the effects are increasing in the clarity and quality of generated audio. Implications of these results for consumers, policymakers, and society are discussed. This paper has been This paper was accepted by D. J. Wu for the Special Issue on the Human-Algorithm Connection.

Calling All Issuers: The Market for Debt Monitoring
Authors: Chen Huaizhi , Cohen Lauren , Liu Weiling 
Published: November 2024

Ninety-five percent of long-term municipal bonds have callable features, and yet, we find new evidence of a substantial fraction of local governments exercising these valuable options suboptimally, with significant delays—resulting in sizable losses. Using data from 2001 to 2019, we estimate that U.S. municipals lost over $26 billion from delayed refinancing, whereas the entire U.S. corporate sector, facing the same low interest-rate environment, lost only a comparatively modest $1.4 billion. We present evidence that these delays are related to gaps in localized debt monitoring. For instance, when a bond becomes callable in a month that is the fiscal year end of a local government—a particularly busy time for finance departments—the decision to call is delayed significantly longer. A significantly longer delay also occurs when a municipality is faced with waves of calls all coming due at once. These effects are magnified in smaller municipalities staffed with smaller finance departments. Moreover, the market for outside monitoring (e.g., underwriters) is a fractured one. It is characterized by extreme stickiness; 87% of a municipality’s bonds are issued with the same underwriter over our sample period. The usage of a less locally focused underwriter is associated with significantly greater delays. This paper was accepted by Tomasz Piskorski, finance.

Financial Statement Audits and Data Breaches
Authors: Liu Lisa Yao 
Published: November 2024

Financial statement audits for public companies require auditors to test the internal controls over the client’s information systems that are material to the financial reporting process. Given the increasingly integrated nature of corporate data and control systems, a standard audit may have a positive effect on client firms’ other information systems, such as those that help prevent data breaches. In this paper, I provide evidence on whether and how auditors help prevent data breaches. Using plausibly exogenous improvements in auditing due to regulatory inspections and auditors’ cross-client learning, I find a decreased likelihood of data breaches among these auditors’ clients. Institutional insights gathered from interviews with accounting firm partners and industry professionals suggest two mechanisms for the role of auditors in preventing data breaches: the provision of relevant information and incentives for internal controls. Collectively, the findings provide evidence that improving accounting information systems can have a positive impact on nonaccounting systems. This paper was accepted by Ranjani Krishnan, accounting.

Information Design and Sharing in Supply Chains
Authors: Caldentey René , Giloni Avi , Hurvich Clifford , Zhang Yichen 
Published: November 2024

We study the interplay between inventory replenishment policies and information sharing in the context of a two-tier supply chain with a single supplier and a single retailer serving an independent and identically distributed Gaussian market demand. We investigate how the retailer’s inventory policy impacts the supply chain’s cumulative expected long-term average inventory costs [Formula: see text] in two extreme information-sharing cases: (a) full information sharing and (b) no information sharing. To find the retailer’s inventory policy that minimizes [Formula: see text], we formulate an infinite-dimensional optimization problem whose decision variables are the MA([Formula: see text]) coefficients that characterize a stationary ordering policy. Under full information sharing, the optimization problem admits a simple solution and the optimal policy is given by an MA(1) process. On the other hand, to solve the optimization problem under no information sharing, we reformulate the optimization from its time domain formulation to an equivalent z-transform formulation in which the decision variables correspond to elements of the Hardy space H2. This alternative representation allows us to use a number of results from H2 theory to compute the optimal value of [Formula: see text] and characterize a sequence of ϵ-optimal inventory policies under some mild technical conditions. By comparing the optimal solution under full information sharing and no information sharing, we derive a number of important practical takeaways. For instance, we show that there is value in information sharing if and only if the retailer’s optimal policy under full information sharing is not invertible with respect to the sequence of demand shocks. Furthermore, we derive a fundamental mathematical identity that reveals the value of information sharing by exploiting the canonical Smirnov–Beurling inner–outer factorization of the retailer’s orders when viewed as an element of H2. We also show that the value of information sharing can grow unboundedly when the cumulative supply chain costs are dominated by the supplier’s inventory costs. Funding: R.

A Hierarchical Approach to Robust Stability of Multiclass Queueing Networks
Authors: Zhao Feiyang , Gurvich Itai , Hasenbein John J. 
Published: November 2024

Robust Stability in Multiclass Queueing Networks: A New Approach In “A Hierarchical Approach to Robust Stability of Multiclass Queueing Networks,” F. Zhao, I. Gurvich, and J. Hasenbein introduce a framework to identify sufficient conditions under which a network’s stability is robust to the distributed choices of resources about their (local) prioritization of jobs. The framework produces sufficient conditions for such stability by relating it to robust optimization problems where the collection of priority policies plays the role of the uncertainty set. Interestingly, within the studied family of policies, robust stability for any policy is inherited from the stability of the special “corner” policies, which are none other than simple static-priority policies.

Published: November 2024

AimsWe aimed to compare reoperations following distal radial fractures (DRFs) managed with early fixation versus delayed fixation following initial closed reduction (CR).MethodsWe used administrative databases in Ontario, Canada, to identify DRF patients aged 18 years or older from 2003 to 2016. We used procedural and fee codes within 30 days to determine which patients underwent early fixation (≤ seven days) or delayed fixation following CR. We grouped patients in the delayed group by their time to definitive fixation (eight to 14 days, 15 to 21 days, and 22 to 30 days). We used intervention and diagnostic codes to identify reoperations within two years. We used multivariable regression to compare the association between early versus delayed fixation and reoperation for all patients and stratified by age (18 to 60 years and > 60 years).ResultsWe identified 14,960 DRF patients, 8,339 (55.7%) of whom underwent early surgical fixation (mean 2.9 days (SD 1.8)). In contrast, 4,042 patients (27.0%) underwent delayed fixation between eight and 14 days (mean 10.2 days (SD 2.2)), 1,892 (12.7%) between 14 and 21 days (mean 17.5 days (SD 1.9)) and 687 (4.6%) > 21 days (mean 24.8 days (SD 2.4)) post-fracture. Patients who underwent delayed fixation > 21 days post-fracture had a higher odds of reoperation (odds ratio (OR) 1.33 (95% CI 1.11 to 1.79) vs early fixation). This worsened for patients aged > 60 years (OR 1.69 (95% CI 1.11 to 2.79)). We found no difference in the odds of reoperation for patients who underwent delayed fixation within eight to 14 or 15 to 21 days post-fracture (vs early fixation).ConclusionThese data suggest that DRF patients with fractures with unacceptable reduction following CR should be managed within three weeks to avoid detrimental outcomes. Prospective studies are required to confirm these findings.Cite this article: Bone Joint J 2024;106-B(11):1257–1262.
ISTA Award 2023: Toward functional reconstruction of the pre-diseased state in total knee arthroplasty

Published: November 2024

AimsThe surgical target for optimal implant positioning in robotic-assisted total knee arthroplasty remains the subject of ongoing discussion. One of the proposed targets is to recreate the knee’s functional behaviour as per its pre-diseased state. The aim of this study was to optimize implant positioning, starting from mechanical alignment (MA), toward restoring the pre-diseased status, including ligament strain and kinematic patterns, in a patient population.MethodsWe used an active appearance model-based approach to segment the preoperative CT of 21 osteoarthritic patients, which identified the osteophyte-free surfaces and estimated cartilage from the segmented bones; these geometries were used to construct patient-specific musculoskeletal models of the pre-diseased knee. Subsequently, implantations were simulated using the MA method, and a previously developed optimization technique was employed to find the optimal implant position that minimized the root mean square deviation between pre-diseased and postoperative ligament strains and kinematics.ResultsThere were evident biomechanical differences between the simulated patient models, but also trends that appeared reproducible at the population level. Optimizing the implant position significantly reduced the maximum observed strain root mean square deviations within the cohort from 36.5% to below 5.3% for all but the anterolateral ligament; and concomitantly reduced the kinematic deviations from 3.8 mm (SD 1.7) and 4.7° (SD 1.9°) with MA to 2.7 mm (SD 1.4) and 3.7° (SD 1.9°) relative to the pre-diseased state. To achieve this, the femoral component consistently required translational adjustments in the anterior, lateral, and proximal directions, while the tibial component required a more posterior slope and varus rotation in most cases.ConclusionThese findings confirm that MA-induced biomechanical alterations relative to the pre-diseased state can be reduced by optimizing the implant position, and may have implications to further advance pre-planning in robotic-assisted surgery in order to restore pre-diseased knee function.Cite this article: Bone Joint J 2024;106-B(11):1231–1239.

AimsThis multicentre retrospective observational study’s aims were to investigate whether there are differences in the occurrence of radiolucent lines (RLLs) following total knee arthroplasty (TKA) between the conventional Attune baseplate and its successor, the novel Attune S+, independent from other potentially influencing factors; and whether tibial baseplate design and presence of RLLs are associated with differing risk of revision.MethodsA total of 780 patients (39% male; median age 70.7 years (IQR 62.0 to 77.2)) underwent cemented TKA using the Attune Knee System) at five centres, and with the latest radiograph available for the evaluation of RLL at between six and 36 months from surgery. Univariate and multivariate logistic regression models were performed to assess associations between patient and implant-associated factors on the presence of tibial and femoral RLLs. Differences in revision risk depending on RLLs and tibial baseplate design were investigated with the log-rank test.ResultsThe conventional and novel Attune baseplates were used in 349 (45%) and 431 (55%) patients, respectively. At a median follow-up of 14 months (IQR 11 to 25), RLLs were present in 29% (n = 228/777) and 15% (n = 116/776) of the tibial and femoral components, respectively, and were more common in the conventional compared to the novel baseplate. The novel baseplate was independently associated with a lower incidence of tibial and femoral RLLs (both regardless of age, sex, BMI, and time to radiograph). One- and three-year revision risk was 1% (95% CI 0.4% to 1.9%)and 6% (95% CI 2.6% to 13.2%), respectively. There was no difference between baseplate design and the presence of RLLs on the the risk of revision at short-term follow-up.ConclusionThe overall incidence of RLLs, as well as the incidence of tibial and femoral RLLs, was lower with the novel compared to the conventional tibial Attune baseplate design, but higher than in the predecessor design and other commonly used TKA systems.Cite this article: Bone Joint J 2024;106-B(11):1240–1248.

Published: November 2024

AimsIn patients with a failed radial head arthroplasty (RHA), simple removal of the implant is an option. However, there is little information in the literature about the outcome of this procedure. The aim of this study was to review the mid-term clinical and radiological results, and the rate of complications and removal of the implant, in patients whose initial RHA was undertaken acutely for trauma involving the elbow.MethodsA total of 11 patients in whom removal of a RHA without reimplantation was undertaken as a revision procedure were reviewed at a mean follow-up of 8.4 years (6 to 11). The range of motion (ROM) and stability of the elbow were recorded. Pain was assessed using a visual analogue scale (VAS). The functional outcome was assessed using the Mayo Elbow Performance Score (MEPS), the Oxford Elbow Score (OES), and the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH). Radiological examination included the assessment of heterotopic ossification (HO), implant loosening, capitellar erosion, overlengthening, and osteoarthritis. Complications and the rate of further surgery were also recorded.ResultsThe indications for removal of the implant were stiffness in five patients, aseptic loosening in five, and pain attributed to the RHA in three. The mean time interval between RHA for trauma to removal was ten months (7 to 21). Preoperatively, three patients had overlengthening of the implant, three had capitellar erosion, six had HO, and four had radiological evidence of loosening. At the final follow-up, the mean the flexion-extension arc improved significantly by 38.2° (95% CI 20 to 59; p = 0.002) and the mean arc of prono-supination improved significantly by 20° (95% CI 0 to 72.5; p = 0.035). The mean pain VAS score improved significantly by 3.5 (95% CI 2 to 5.5; p = 0.004). The mean MEPS improved significantly by 27.5 (95% CI 17.5 to 42.5; p = 0.002). The mean OES improved significantly by 9 (95% CI 2.5 to 14; p = 0.012), and the mean DASH score improved significantly by 23.5 (95% CI 7.5 to 31.6; p = 0.012). Ten patients (91%) had HO and osteoarthritis. Two patients underwent further surgery due to stiffness and pain, respectively.ConclusionSimple removal of the implant at revision surgery following a failed RHA introduced following trauma provides satisfactory mid-term results with an acceptable risk of complications. Osteoarthritis, instability, and radioulnar impingement were not problems in this series.Cite this article: Bone Joint J 2024;106-B(11):1327–1332.
Core Outcome Domains for Elbow Replacement (CODER)
Authors: Watts Adam C. , McDaid Catriona , Hewitt Catherine 
Published: November 2024

AimsA review of the literature on elbow replacement found no consistency in the clinical outcome measures which are used to assess the effectiveness of interventions. The aim of this study was to define core outcome domains for elbow replacement.MethodsA real-time Delphi survey was conducted over four weeks using outcomes from a scoping review of 362 studies on elbow replacement published between January 1990 and February 2021. A total of 583 outcome descriptors were rationalized to 139 unique outcomes. The survey consisted of 139 outcomes divided into 18 domains. The readability and clarity of the survey was determined by an advisory group including a patient representative. Participants were able to view aggregated responses from other participants in real time and to revisit their responses as many times as they wished during the study period. Participants were able to propose additional items for inclusion. A Patient and Public Inclusion and Engagement (PPIE) panel considered the consensus findings.ResultsA total of 45 respondents completed the survey. Nine core mandatory domains were identified: ‘return to work or normal daily role’; delivery of care was measured in the domains ‘patient satisfaction with the outcome of surgery’ and ‘would the patient have the same operation again’; ‘pain’; ‘revision’; ‘elbow function’; ‘independence in activities of daily living’; ‘health-related quality of life’; and ‘adverse events’. ‘Elbow range of motion’ was identified as important by consensus but was felt to be less relevant by the PPIE panel. The PPIE panel unanimously stated that pain should be used as the primary outcome domain.ConclusionThis study defined core domains for the clinical outcomes of elbow replacement obtained by consensus from patients, carers, and healthcare professionals. Pain may be used as the primary outcome in future studies, where appropriate. Further work is required to define the instruments that should be used.Cite this article: Bone Joint J 2024;106-B(11):xxx–xxx.
Management of the infected total elbow arthroplasty
Authors: Sanchez-Sotelo Joaquin 
Published: November 2024

Periprosthetic joint infection represents a devastating complication after total elbow arthroplasty. Several measures can be implemented before, during, and after surgery to decrease infection rates, which exceed 5%. Debridement with antibiotics and implant retention has been reported to be successful in less than one-third of acute infections, but still plays a role. For elbows with well-fixed implants, staged retention seems to be equally successful as the more commonly performed two-stage reimplantation, both with a success rate of 70% to 80%. Permanent resection or even amputation are occasionally considered. Not uncommonly, a second-stage reimplantation requires complex reconstruction of the skeleton with allografts, and the extensor mechanism may also be deficient. Further developments are needed to improve our management of infection after elbow arthroplasty.Cite this article: Bone Joint J 2024;106-B(11):1321–1326.
