Race, Work, and Disability in Progressive Era United States
Authors: Lawrie Paul 
Published: September 2022

Abstract
Throughout U.S. history, the production of difference, whether along racial or disability lines, has been inextricably tied to the imperatives of labor economy. From the plantations of the antebellum era through the assembly lines and trenches of early-twentieth-century America, ideologies of race and disability have delineated which peoples could do which kinds of work. The ideologies and identities of race, work, and the “fit” ’ or “unfit” body informed Progressive Era labor economies. Here the processes of racializing or disabling certain bodies are charted from turn-of-the-century actuarial science, which monetized blacks as a degenerate, dying race, through the standardized physical and mental testing and rehabilitation methods developed by the U.S. army during World War I. Efforts to quantify, poke, prod, or mend black bodies reshaped contemporary understandings of labor, race, the state, and the working body.

Abstract
Hemorrhage is the leading cause of trauma-related deaths, in hospital and prehospital settings. Hemostasis is a complex mechanism that involves a cascade of clotting factors and proteins that result in the formation of a strong clot. In certain surgical and emergency situations, hemostatic agents are needed to achieve faster blood coagulation to prevent the patient from experiencing a severe hemorrhagic shock. Therefore, it is critical to consider appropriate materials and designs for hemostatic agents. Many materials have been fabricated as hemostatic agents, including synthetic and naturally derived polymers. Compared to synthetic polymers, natural polymers or biopolymers, which include polysaccharides and polypeptides, have greater biocompatibility, biodegradability and processibility. Thus, in this review, we focus on biopolymer-based hemostatic agents of different forms, such as powder, particles, sponges and hydrogels. Finally, we discuss biopolymer-based hemostatic materials currently in clinical trials and offer insight into next-generation hemostats for clinical translation.
Do your troubles today seem further away than yesterday? On sleep’s role in mitigating the blushing response to a reactivated embarrassing episode
Authors: Reinhold Faya L , Gerlicher Anna M V , van Someren Eus J W , Kindt Merel 
Published: September 2022

Abstract
The “sleep to forget and sleep to remember hypothesis” proposes that sleep weakens the emotional tone of an experience while preserving or even enhancing its content. Prior experimental research however shows contradictory findings on how emotional reactivity changes after a period of sleep, likely explained by methodological variations. By addressing these inconsistencies, we investigated the mitigating effect of overnight sleep on emotional reactivity triggered by memory reactivation. Using a karaoke paradigm, we recorded participants’ singing of two songs, followed by exposing them to one of the recordings (rec1) to induce an embarrassing episode. After a 12-hr period of either day-time wakefulness (N = 20) or including nighttime sleep (N = 20), we assessed emotional reactivity to the previously exposed recording (rec1) and the newly exposed recording (rec2). Emotional reactivity was assessed with a physiological measure of facial blushing as the main outcome and subjective ratings of embarrassment and valence. Sleep and wake were monitored with diaries and actigraphy. The embarrassing episode was successfully induced as indicated by objective and subjective measures. After controlling for an order effect in stimulus presentation, we found a reduction in blushing response to the reactivated recording (rec1) from pre- to post-sleep compared to wakefulness. However, emotional reactivity to the reactivated recording (rec1) and the new recording (rec2) did not differ after sleep and wakefulness. This study shows that facial blushing was reduced following overnight sleep, while subjective ratings were unaffected. Whether the beneficial effect of sleep is due to changes in memory representation or rather emotion regulation remains elusive.

Published: September 2022

AbstractThe operation of the China Railway Express features numerous links across several regions and countries. Effectively controlling the risks involved in the operation of the China Railway Express is crucial for ensuring safety and efficiency and promoting the sustainable development of the China Railway Express. The Bayesian network-based risk-management model was built corresponding to the actual operation of the China Railway Express; the model used an advanced risk-management theory. The sensitivity analysis of risk factors and Bayesian network inference were realized using the expectation-maximization and clique-tree propagation algorithms. Using the risk-checklist method, 17 risk-related factors were analysed on 17 nodes of the Bayesian network from three perspectives—safety, efficiency and effectiveness—based on expert opinions and the actual operating conditions of the China Railway Express. Data from a sensitivity analysis and evidence inference of the Bayesian network model indicated that the sensitivity coefficients of nodes N01, N04, N07, N08 and N17 of the network were high. Moreover, the risk-occurrence probabilities for nodes N01, N04, N06, N07 and N09 were higher in the case of reverse inference. Our results revealed the crucial factors influencing the risk. The identified risk factors included the stability of the political environment in countries along the route, conditions of station infrastructures and the complexity of the process of changing rails and reloading. Further, risk-management suggestions were provided. By establishing a sound risk-management framework, reliable assessment and management could be realized in accordance with changes in the operating conditions of the China Railway Express.

Published: September 2022

Study Design.
Pre-clinical biomechanical study of topology-optimization versus standard ring design for bioresorbable poly-ε-caprolactone cervical spine fusion cages delivering BMP-2 using a porcine model.

Objective.
To evaluate range of motion (ROM) and bone fusion, as a function of topology optimization and bone morphogenetic protein-2 (BMP-2) delivery method.

Summary of Background Data.
3D printing technology enables fabrication of topology-optimized cages using bioresorbable materials, offering several advantages including customization, and lower stiffness. Delivery of BMP-2 using topology optimization may enhance the quality of fusion.

Methods.
Twenty-two 6-month old pigs underwent anterior cervical discectomy fusion at one level using 3D-printed PCL cages. Experimental groups (N=6 each) included: Group1: ring design with surface adsorbed BMP-2, Group 2: topology-optimized rectangular design with surface adsorbed BMP-2, and Group 3: ring design with BMP-2 delivery via collagen sponge. Additional specimens, two of each design, were implanted without BMP-2, as controls. Complete cervical segments were harvested 6 months post-op. Nano-CT was performed to assess complete bony bridging. Pure moment biomechanical testing was conducted in all three planes, separately. Continuous 3D motions were recorded and analyzed.

Results.
Three subjects suffered early surgical complications and were not evaluated. Overall, ROM for experimental specimens, regardless of design or BMP-2 delivery method, was comparable, with no clinically significant differences among groups. Among experimental specimens at the level of the fusion, ROM was <1.0° in flexion and extension, indicative of fusion, based on clinically applied criteria for fusion of <2-4°. Despite the measured biomechanical stability, using CT evaluation, complete bony bridging was observed in 40% of the specimens in Group 1, 50% of Group 2, 100% of Group 3, and none of the control specimens.

Conclusion.
A topology optimized PCL cage with BMP-2 is capable of resulting in an intervertebral fusion, similar to a conventional ring-based design of the same bioresorbable material.
A Novel Method of Intra-Abdominal Cavity Obliteration: A Case Report of a Colonic Seromuscular Flap
Authors: Imaizumi Atsushi 
Published: September 2022

Summary:
Obliteration of an organized subphrenic abscess with an enteric fistula is a great challenge, especially after hepatectomy, as most of the conventional flaps used to fill the abscess cavity are not feasible. A seromuscular flap is an innovative option for this purpose because of its proximity to the pathology, flexibility in the size and volume of the flap harvested, antibacterial ability of the muscle flap, and preservation of trunk musculature. We illustrate the use of a colonic seromuscular flap for filling such an abscess and show its long-term change. A 66-year-old man developed a right subphrenic abscess after subsegmentectomy for his hepatocellular carcinoma. Prolonged percutaneous drainage of the abscess was unsuccessful because of the enteric communication with the transverse colon and resulted only in the organization of the abscess cavity. Through the previous laparotomy incision, the involved part of the transverse colon was detached from the abscess. The transverse colon including the fistula was isolated for 16 cm based on the middle colic vessels. Following an enterotomy along the antimesenteric border and mucosal stripping, a colonic seromuscular flap was made. The debrided abscess cavity was properly filled with this flap. The donor colon was repaired. The postoperative course was uneventful without showing any signs of infection for more than 3 years. During this period, the volume of the flap filling the cavity showed significant reduction of 50%. The seromuscular colonic flap is an effective option for filling the intra-abdominal abscess cavity when most of the conventional flaps are not feasible.
Vulvar Pruritus in Postmenopausal Diabetic Women With Candidiasis Secondary to Sodium-Glucose Cotransporter Receptor-2 Inhibitors
Authors: Forman Jessica L. , Mercurio Mary Gail 
Published: September 2022

Vulvar pruritus with external rash in postmenopausal women on sodium-glucose cotransporter receptor-2 inhibitors may indicate vulvovaginal candidiasis, which requires early yeast culture for prompt diagnosis and management.

Objective/Purpose
We present a case series of recurrent vulvovaginal candidiasis (RVVC) secondary to sodium-glucose cotransporter receptor-2 (SGLT2) inhibitor-induced glucosuria in postmenopausal women that resulted in extensive vulvar skin involvement.

Materials and Methods
We describe 5 cases of RVVC presenting primarily with vulvar pruritus and external rash, in type 2 diabetic, postmenopausal women on SGLT2 inhibitor therapy. This work was exempt from institutional review board approval in compliance with the university guidelines for determining human subject research. All patients consented to the use of pictures for educational and research purposes.

Results
All patients developed RVVC, with vulvar cultures positive for Candida albicans and resolution of symptoms after treatment with oral fluconazole. All patients presented primarily with severe vulvar pruritus that developed after beginning treatment with SGLT2 inhibitors (range: 4 wk–16 mo). Given the intermittent nature of symptoms, variable degree of activity at presentation, lack of vaginal discharge, atypical population, and extensive skin involvement, RVVC was not considered initially. Three patients were misdiagnosed with lichen sclerosus and treated with topical steroids, which may have allowed for disease progression. Two patients were prescribed topical estrogen creams for presumed vaginal atrophy. One patient was misdiagnosed with improper vulvar hygiene and neuropathic itch. Because of these diagnostic missteps, 4 patients endured symptomatically for extended periods (range: 2–6 years) without adequate treatment. Four patients have discontinued their SGLT2 inhibitor, all with resolution of vulvar symptoms.

Conclusions
Postmenopausal, diabetic women taking SGLT2 inhibitors presenting with vulvar pruritus and rash require early evaluation for RVVC to prevent misdiagnoses and need for diabetic medication alterations.

Population level genetic memory of prior metabolic adaptation inE. coli
Authors: Katz Sophia , Grajeda-Iglesias Claudia , Agranovich Bella , Ghrayeb Alia , Abramovich Ifat , Hilau Sabrin , Gottlieb Eyal , Hershberg Ruth 
Published: September 2022

AbstractBacteria must often survive following the exhaustion of their external growth resources. Fitting with this need, many bacterial species that cannot sporulate, can enter a state known as long term stationary phase (LTSP) in which they can persist for years within spent media. Several recent studies have revealed the dynamics of genetic adaptation ofEscherichia coliunder LTSP. Yet, the metabolic consequences of such genetic adaptation were not addressed. Here, we characterized the metabolic changes LTSP populations experience and link them to their genetic adaptation. We observed that during growth within fresh resourcesE. coliproduces the short chain fatty acid butyrate, which wildtypeE. colicannot consume. Once resources are otherwise exhausted,E. coliadapts genetically to consume butyrate through the convergent, temporally precise emergence of mutation combinations within genes that regulate fatty acid metabolism. These mutations appear to negatively affect bacterial fitness when butyrate is not available, and hence rapidly decrease in frequency, once all butyrate is consumed. Yet despite this,E. colipopulations show a remarkable capability of maintaining a population-level genetic ‘memory’ of prior adaptation to consume butyrate. The maintenance of such a ‘memory’ allows bacteria to rapidly re-adapt, at an ecological, rather than an evolutionary timeframe, to re-consume previously encountered metabolites.
Comprehensive stiffness analysis of the cylindrical roller bearing for aircraft engines considering the radial clearance
Authors: Ri CholUk , Namgung Hwan , Zhang Zhunhyok , Chae Chunghyok , Ri Kwangil , Ho Pongguk , Zhang Ryong 
Published: September 2022

Purpose
The rotor system supported by the cylindrical roller bearings is widely used in various fields such as aviation, space and machinery due to its importance. In the study of the dynamic characteristics of the cylindrical roller bearings, it is important to accurately calculate the stiffness of the cylindrical roller bearings. The stiffness of the cylindrical roller bearings is very important in the analysis of the vibration characteristics of the rotor system. Therefore, in this paper, the method of creating a comprehensive stiffness model of the cylindrical roller bearing is mentioned. The purpose of this study is to improve the dynamic stability of the rotor system supported by the cylindrical roller bearing by accurately establishing the comprehensive stiffness calculation model of the cylindrical roller bearings.

Design/methodology/approach
In consideration of the radial clearance of the cylindrical roller bearing, the radial load acting on the cylindrical roller bearing was derived, and based on this, a model for calculating the Hertz contact stiffness of the cylindrical roller bearing was created. Based on the load considering the radial clearance, an oil film stiffness model of the cylindrical roller bearing was created under the elastohydrodynamic lubrication (EHL) theory. Then, the comprehensive stiffness was calculated by combining Hertz contact stiffness and the oil film stiffness of the cylindrical roller bearing, and the dynamic parameters are calculated by using the MATLAB program.

Findings
When the radial clearance of the cylindrical roller bearing is considered, the comprehensive stiffness is larger than when the radial clearance is not taken into account, and the radial clearance of the cylindrical roller bearing is an important factor that directly affects the comprehensive stiffness of the cylindrical roller bearing.

Originality/value
In this paper, based on Hertz contact theory and the EHL theory, the authors investigated the method of creating a comprehensive stiffness model of the cylindrical roller bearing considering the radial clearance. These results will contribute to the theoretical basis for studying the mechanics of cylindrical roller bearings and optimizing their structures, and they will provide an important theoretical basis for analyzing the dynamic characteristics of the rotor system supported by the cylindrical roller bearing.
How does tenancy affect farmland prices? Effects of lease status, lease term and buyer type
Authors: Humpesch Maximilian , Seifert Stefan , Balmann Alfons , Hüttel Silke 
Published: September 2022

PurposeLease contracts at the time of sale influence buyers' expectations about future returns of farmland ownership and may thus contribute to price dispersion. This paper investigates the conjecture that existing land lease contracts influence buyers' and sellers' costs of being information deficient and thus their bargaining position, their expectation formation about future returns, and thus ultimately the farmland price.Design/methodology/approachThe authors link different levels of information, search, and bargaining costs to three buyer types and their land use intentions. Relying on a rich dataset of farmland transactions in the German Federal State of Saxony-Anhalt from 2014 to 2019, the authors use a hedonic pricing model to investigate five hypotheses applying multivariate one-sided tests.FindingsThe authors find buyer-specific effects related to lease status and lease term of a lot. Tenant buyers pay less than non-farmer buyers for leased lots, whereas non-tenant farmers pay a markup. While prices decrease for all buyer groups with an increasing lease term, this effect is the strongest for non-tenant farmer buyers. This study’s results suggest that an existing lease contract impacts buyers' costs of being information deficient, their bargaining positions and expectation formation, and ultimately the price discovery process.Originality/valueTo the authors’ knowledge, this is the first study that decomposes the effects of tenancy on farmland prices by buyer type and lease term. The study provides insights into price dispersion for identical characteristics of farmland and explains why empirical studies have found mixed or no empirical evidence that lease contracts influence the price discovery process.
Who one is, whom one knows? Evaluating the importance of personal and social characteristics of influential people in social networks

Published: September 2022

PurposeThis study examines opinion leadership's personal and social characteristics to see which one is more effective in opinion leadership in four different industries: fashion, travel and tourism, wellness and book and literature. The specific subject of this investigation is how largely openness, exhibitionism and competence in interpersonal relationships and status and attitude homophily affect the opinion leadership and the decision-making of opinion leaders' followers.Design/methodology/approachThe proposed model was tested with the questionnaire shared via stories featured on Instagram among followers of four micro-influencers in different industries. For the purpose of testing the offered hypotheses of this study, the partial least squares method was used.FindingsThe findings show that openness, exhibitionism and competence in interpersonal relationships have a substantial effect on opinion leadership. It was also evident that status and attitude homophily impact opinion leadership. The model supports the effect of both personal and social characteristics on opinion leadership; however, based on the results, the effect of personal characteristics on opinion leadership is more remarkable, both in a direct relationship and through the mediating role of para-social interaction.Originality/valueThis study is novel in categorizing opinion leaders' attributes in two different extents of personal and social characteristics. The authors defined a model of the effectiveness of each personal and social characteristic on opinion leaders. The model investigates whether the personal or social characteristics have the most effect on opinion leadership, particularly with the mediating role of para-social interaction.
