Creators Matter. Perception and Pricing of Art Made by Human, Cyborgs and Humanoid Robots
Authors: Fortuna Paweł , Modliński Artur , McNeill Monika
Published: December 2022

Not only does the art market include human and nonhuman creators, it also incorporates technologically augmented artists, called cyborgs. They use wearables, sensors, chips, and even new organs to process various stimuli, such as electromagnetic radiation, atmospheric pressure, or ultraviolet rays, to produce artworks. Little is known however, how the objects produced by them are perceived by the art recipients. This paper applies an experimental study with 373 non-experts in the field of art. The results show that the perceived value of the painting depends on the type of agent and on the context of the evaluation. The price of objects created by a human artist is significantly higher if the context cue is the price of the canvas made by humanoid robot than another human. People value cyborg's artwork similarly to human-generated artwork when contextual cue is human, and similarly to robot-generated artwork when contextual cue is humanoid robot.
Rapidly progressive femoral head necrosis due to post-traumatic Brucella hip infection: a case report
Authors: Hu Wei-Yang , Ren Guang-Zong , Lv Jia-Jin , Chen Gui-Yue
Published: December 2022

Brucellosis is a common zoonotic infectious disease worldwide that can affect almost all organs in the human body. Osteonecrosis of the femoral head has numerous possible causes. Patients usually experience movement disorders, severe pain, and an extremely high disability rate. We herein describe a 32-year-old male farmer living in Shanxi, China who accidentally injured his right hip while working. After 1 month of rest, the pain in the right hip was relieved, and the patient began to walk again. However, after 2 months of walking, he developed aggravated pain and claudication in the right lower limb. Examination revealed shortening of the right lower limb. We carried out a comprehensive and systematic examination and performed total hip arthroplasty. Hip trauma with Brucella infection may progress to osteonecrosis of the femoral head in a short period of time without typical symptoms of Brucella infection. Systematic examination and treatment should be performed at an early stage to prevent the eventual deterioration of the disease and serious complications that are difficult to treat.
Limb-shaking transient ischemic attack in posterior circulation ischemia: a case report
Authors: Zhao Zhihong , Qin Jie
Published: December 2022

Limb-shaking transient ischemic attack (LS-TIA) is a rare clinical manifestation of steno-occlusive carotid lesions. Reports of LS-TIA caused by posterior circulation ischemia are rare. Here, the case of a 56-year-old male patient with a history of epilepsy, who presented with dizziness, nausea and vomiting, is reported. Initial brain magnetic resonance imaging (MRI) indicated no signs of acute ischemia, and the patient’s symptoms had not relieved despite drug administration to treat dizziness. During a vestibular function test on the next day, he developed sudden left-limb shaking without disturbance of consciousness or facial twitching. Considering a seizure, an anti-epileptic drug was administered, but no improvement was observed. Eight hours later, the patient experienced left-limb paralysis, and re-examination of the MRI indicated brainstem infarction. The patient recovered well with antiplatelet and antiatherosclerotic therapy. While LS-TIA is a rare manifestation of TIA of the carotid arterial system, posterior circulation ischemia may also manifest as LS-TIA. If a patient presents with limb shaking due to postural changes despite a history of epilepsy, LS-TIA should be highly suspected.
J. E. Quibell’s 1894–95 Ballas Excavation: Interim Report on the Second–Fourth Dynasty Cemeteries
Authors: Vanthuyne Bart
Published: December 2022

In 1894–95 W. M. F. Petrie and J. E. Quibell conducted excavations in the Naqada-Ballas region (Fifth Upper Egyptian nome). While Petrie’s later work in and around ancient Nubt received plenty of attention, Quibell’s Ballas work was wrongfully largely ignored, even though he likewise made substantial contributions to the Naqada excavations. With the progressive rediscovery of field notebooks, diaries, and pottery documentation of Petrie, Quibell and others, as well as past and ongoing museum work, it is now possible to reassess Quibell’s excavations at Zawaydah/North Town and the Ballas cemeteries further south, where he discovered a Predynastic settlement, many Predynastic burials, as well as Early Dynastic, early Old Kingdom, Middle Kingdom and early New Kingdom tombs. The current article will outline the above and show how this information can be used for the study of the Second–Fourth Dynasty cemeteries, as well as the tomb types, burial customs and origin of the buried population.
Holistic Approach to Evaluating the Sustainability and Resiliency of Buried Drainage Structures Relative to Climate Change
Authors: Pluimer Michael L.
Published: December 2022

A research project was conducted in 2020 to assess the sustainability and resiliency of various buried drainage structures relative to the impacts of climate change and extreme weather events. As a result of this project, a risk assessment and rating system was proposed that calculates the risks that various extreme weather events, natural disasters, and other threats pose to buried drainage structures. One thing that differentiates this proposed risk assessment methodology from others is its holistic approach to sustainability and resiliency. The basis for this holistic approach is that the use of less sustainable materials contributes more to climate change, which in turn exacerbates the magnitudes and frequencies of extreme weather events, thereby increasing the importance of resiliency in buried drainage structures. Because of this relationship, the proposed risk index calculations and vulnerability ratings take into account factors assessing both the sustainability and resiliency of buried drainage structures.
Role of discontinuous fiber core material on the mechanical behavior of hybrid sandwich polyester composites
Authors: Larson Richard , Jamora Von C , Sattar Siavash , Kravchenko Sergii G , Kravchenko Oleksandr G
Published: December 2022

This study investigated the potential for improving the mechanical behavior of glass fiber polyester composites by using symmetric hybrid sandwich configurations that combine continuous woven composite and different discontinuous reinforcements used as a core. The discontinuous reinforcements included sheet molding compound (SMC), bulk molding compound (BMC), and the discontinuous prepreg based platelets that were chopped from the woven trim scrap. Hybrid sandwich configurations using different core materials exhibited improvements in flexural mechanical properties, while providing more progressive failure under both flexural and compressive loading. Compressive strength in polyester SMC and woven laminate was significantly lower than flexural strength, while BMC and chopped platelets exhibited similar levels of strength in flexure and compression. Overall, hybridized compression molding produced sandwich structures can be used to control the failure progression and to improve the structural characteristics of composite, especially under flexural loads. The trim scrap core sandwich configuration had mechanical properties comparable with the BMC core hybrid. Therefore, trim scrap upcycling can be an efficient approach to reducing the amount of material waste during the manufacturing.
Peripheralization Processes as a Contextual Source of Populist Vote Choices: Evidence from the Czech Republic and Eastern Germany
Authors: Dvořák Tomáš , Zouhar Jan
Published: December 2022

The existing research on contextual sources of support for populist parties has revolved around two factors: the unemployment rate and the size of immigrant groups. Conceived as residential characteristics, observation of these factors has been seen to increase support for radical parties in Western European countries. We identify different contextual (non-individual) drivers of support for populist parties in the post-communist Czech Republic (Czechia). Based on a large sample of voters ( n = 23,734), we identify the (contextual) effect of economic hardship and demographic decline on support for populist parties. We interpret these results as supporting the theory of regional peripheralization. This peripheralization has been identified to be particularly strong in the post-communist countries of Central and Eastern Europe, and has widened regional socio-economic disparities in this region. We show how these processes have affected voting behaviour and support for political parties. In a second step, we use a sample from eastern Germany ( n = 524) to test whether peripheralization affects support for populist parties in other post-communist regions. The results confirm the hypothesis also in the case of east Germany. Our study contributes to the debate by pointing out a novel mechanism that leads to increased support for radical and moderate populist parties.
Economic Strain in Post-Communist Countries and the Rest of Europe: Attitudes Towards the Unemployed and the Old
Authors: Basna Kristyna
Published: December 2022

This paper investigates attitudes towards the welfare state measured as government responsibility towards the standard of living of the unemployed and the old. The article focuses on the differences between post-communist countries and the rest of Europe, contextualised using the self-interest theory, specifically economic strain. Data on thirty one European countries gleaned from the European Social Survey collected in 2008 and 2016 are analysed using multilevel methods. The findings show that even though citizens in post-communist countries are purportedly more in favour of government intervention in regard to the welfare state, perceptible differences emerge based on individual characteristics, namely economic strain, combined with whether the respondent lives in a post-communist country. The cross-national differences in welfare support between post-communist countries and the rest of Europe are largely driven by differences in economic strain, with citizens in post-communist countries that struggle financially exhibiting higher support for welfare state provisions in comparison to their peers in countries without a communist legacy.
Apixaban-Associated Intracranial Hemorrhage in a Patient With Elevated International Normalized Ratio
Authors: Pathan Sophia , Genco Andrew T.
Published: December 2022

Apixaban has been associated with prolongation of the international normalized ratio (INR), but data surrounding the extent of elevation and its clinical significance are limited. Due to interaction between apixaban and the prothrombin assay, elevations in INR in patients receiving apixaban are common and not always grounds for concern. However, in high risk patients, elevations can represent a need for closer monitoring. This case summarizes an 82-year-old woman with a history of atrial fibrillation and left middle cerebral artery strokes with no residual deficits. She presented with right-sided hemiparesis and aphasia and underwent a mechanical thrombectomy with TICI 2b recanalization of a left M1 occlusion. Post-thrombectomy, she was found to have a left atrial thrombus and 10 days later was started on apixaban 5 mg twice daily. On the fourth day of apixaban therapy, she experienced an INR increase to 2.3, prompting initiation of a vitamin K challenge for nutritional deficiency. Despite initial improvement, her INR increased to 2.7 a week after apixaban was initiated, coinciding with a decline in mental status and an apixaban peak level of 435.6 ng/mL (reference range 91-321 ng/mL). A computed tomography (CT) scan of her head showed new intracranial hemorrhage in the area of her previous infarction, prompting apixaban reversal with andexanet alfa. Unfortunately, the patient expired. This case report highlights the importance and difficulty in performing therapeutic drug monitoring in patients receiving oral anti-factor Xa inhibitors, revealing a downside to administration of high-risk medications that do not have readily available monitoring.
A simplified approach to develop fuzzy logic controller with disturbance estimator for control of a planar parallel (2PRP-PPR) motion platform
Authors: Choudhury Rutupurna , Londhe Pandurang , Mohan Santhakumar , Singh Yogesh
Published: December 2022

This work presents, a robust position tracking control of a 3-degrees of freedom 2PRP-PPR (P: Active Prismatic joint, P: Passive prismatic joint, R; Revolute joint) parallel motion mechanism. For controlling the motion of the defined platform, a simple method to develop a fuzzy logic controller called as robust single input fuzzy logic control (RSIFLC) algorithm is presented and used for the complex workspace trajectory tracking control problem with the existence of outside disturbances, variable uncertainties, and inner noises. The suggested control method comprises two sections: The first section considers a feed-forward expression to increase control action and a disturbance estimator to account for anonymous factors like outer disturbances and un-modeled dynamics. The second section employs single input fuzzy logic control as a feedback component to improve the system’s overall closed-loop stability. The experimental results demonstrate the superiority of the suggested control algorithm over traditional control schemes.
Optimization of Titanium Grade 2 sheet forming by roller blank holder method
Authors: Seçgin Ömer , Özsert İbrahim
Published: December 2022

Incremental forming is a rapid prototype production method, which can be used in different industrial applications. In this context, it can be used especially in forming of Titanium Grade 2 sheet as depending on the types of manufacture. The main problem of the incremental forming method is that the wall thickness of the piece obtained after the process is not homogeneous. In this study, Titanium Grade 2 sheet was formed 60° axially symmetrical cone geometry using the roller blank holder method (TPIF-RL), which is a new approach. This method provides bigger wall thickness than the conventional incremental forming method considering its results. In this study, it was aimed to investigate the effectiveness of the new roller blank holder method on titanium material. In the experiments, the axisymmetrical piece with a height of 40 mm was formed (the forming angle is 60° with the horizontal). Feedrate, clamping pressure, increment, and forming tool diameter were used as parameters. Forming force, surface roughness, and wall thickness distributions obtained as a result of experimental studies were examined statistically. The interactions of the parameters were evaluated, and optimum levels of forming parameters were determined for the roller blank holder method. In addition, by using gray relational analysis, parameter levels of three dependent variables (forming force, surface roughness, and sheet thickness) were defined to optimize at the same time. As a result, bigger wall thickness was obtained with a low clamping force considering roller blank holder method. It was determined the levels that optimize the three parameters together were 2 bar pressure, 500 mm/min feed rate, 0.25 mm increment, and 5 mm forming tool diameter. Bigger wall thickness was obtained with a low clamping force considering roller blank holder method.
Relapses are common in severe hematologic systemic lupus erythematosus and may be prevented by early institution of immunosuppressive agents: Α real-life single-center study
Authors: Moysidou Georgia-Savina , Garantziotis Panagiotis , Nikolopoulos Dionysis , Katsimbri Pelagia , Fanouriakis Antonis , Boumpas Dimitrios T
Published: December 2022

Background

Hematologic manifestations are common in systemic lupus erythematosus (SLE), either at initial presentation or during the course of the disease, but data regarding their natural history are scarce.

Objective

To describe the characteristics, treatments, and outcomes of severe hematological manifestations in a large cohort of lupus patients.

Methods

Retrospective cohort study of patients in the “Attikon” lupus cohort who had a history of a severe hematologic manifestation, defined as autoimmune hemolytic anemia (AIHA) with hemoglobin < 8 g/dL, thrombocytopenia with platelet count < 30,000/mm3, Evans syndrome with hemoglobin < 8 g/dL, and/or platelet count < 30,000/mm3, neutropenia with < 500 neutrophils/mm3, thrombotic microangiopathy (TMA)/thrombotic thrombocytopenic purpura (TTP)-like syndrome, or macrophage activation syndrome (MAS). Demographic and clinical characteristics, treatments, and outcomes were recorded.

Results

From over 300 patients with hematologic manifestations, 41 qualified as severe (70.7% women, mean [SD] age at SLE diagnosis 42.6 [18.0] years). Hematologic manifestations preceded SLE diagnosis in 13 patients (31.7%), was concomitant to SLE diagnosis in 16 patients (39%), and occurred during the course of the disease in 12 (29.3%) patients, with a mean (SD) disease duration of 8.7 (5.5) years. Thrombocytopenia was the most common severe hematological manifestation (56.1%), followed by AIHA (17.1%) and TTP-like syndrome (12.2%). For initial treatment, all patients were treated with glucocorticoids (GC), while rituximab and cyclophosphamide were the most frequently used immunosuppressive agents. Following initial treatment, relapse occurred in 22 patients (53.7%). Compared to patients that did not relapse, those that relapsed had less often received concomitant immunosuppressive agents following treatment of initial episode ( n = 17/23, 73.9% vs 5/17, 29.4%, p = 0.005).

Conclusion

Severe hematologic disease in SLE has a high risk of relapse, which may be mitigated by the early institution of GC-sparing agents.
Influence of fungal decay on mechanical properties of bio-based sheet molding compounds (SMC)
Authors: Gortner Florian , Schüffler Anja , Fischer-Schuch Jochen , Mitschang Peter , Bachmann Paula
Published: December 2022

Sheet Molding Compound (SMC) was initially developed in the 1960s and enabled for the first time the production of glass fiber reinforced polymer composite in mass scale production and at an advantageous price. Today, material and process are well established for the production of semi-structural and structural components in various applications such as construction industry, aircraft applications and automotive components. Based on increasing ecological and economical requirements for construction materials a newly and largely bio-based SMC semi-finished material was developed. This paper shows the ability using bio-based components to replace crude oil and mineral based components in SMC. Therefore, test methods for shelf life and fungal decay tests were developed to prove that there is no influence to mechanical properties of the bio-based specimens. The different test series showed that there is a bigger influence of sample preparation for shelf life tests than from fungal decay to the specimens.
Algorithmic management and collective bargaining
Authors: De Stefano Valerio , Taes Simon
Published: December 2022

This article addresses the challenges raised by the introduction of algorithmic management and artificial intelligence in the world of work, focusing on the risks that new managerial technologies present for fundamental rights and principles, such as non-discrimination, freedom of association and the right to privacy. The article argues that collective bargaining is the most suitable regulatory instrument for responding to these challenges, and that current EU legislative initiatives do not adequately recognise the role of collective bargaining in this area. It also maps current initiatives undertaken by national trade union movements in Europe to govern algorithmic management.
Validation and method comparison for a point-of-care lateral flow assay measuring equine whole blood insulin concentrations
Authors: Berryhill Emily H. , Urbina Naomi S. , Marton Sam , Vernau William , Alonso Flavio H.
Published: December 2022

The Wellness Ready Test (WRT) is a lateral flow, stall-side assay that measures equine insulin in whole blood and requires validation before recommending clinical use. We evaluated intra- and inter-assay precision and linearity and compared the WRT with a radioimmunoassay (RIA). Tested concentrations ranged from <139 to >695 pmol/L (<20 to >100 μIU/mL). For 20 replicates at each insulin level, intra-assay CVs of the WRT for insulin were 13.3%, 12.9%, and 15.3% at low (139–278 pmol/L; 20–40 μIU/mL), intermediate (278–417 pmol/L; 40–60 μIU/mL), and high (>417 [Formula: see text] >60 μIU/mL) concentrations, respectively. For 10 replicates at each level (3 assay lots), inter-assay CVs were 15.9%, 11.0%, and 11.7%, respectively. In the weighted linear regression of 5 measured insulin concentrations against expected concentrations, R2 = 0.98, slope = 1.02, and y-intercept = 14.4 pmol/L (2.08 μIU/mL). The Spearman correlation coefficient ( rs) was 0.90 (95% CI: 0.85–0.94) between the WRT and RIA; the WRT = f(RIA) Passing–Bablok regression yielded the fit, y = 1.005x + 24.3 pmol/L (3.50 μIU/mL). The WRT result averaged 10.4% higher than the RIA result, with targeted bias of 25.9, 26.1, and 26.7 pmol/L (3.74, 3.76, and 3.84 μIU/mL) for cutoffs used to diagnose insulin dysregulation of 312, 347, and 451 pmol/L (45, 50, and 65 μIU/mL). Assay clinical sensitivities, specificities, and accuracies determined at the 3 selected clinical cutoffs and using the RIA as gold standard were 87–95%, 92–96%, and 91–95%, respectively ( n = 99 samples). Observed total error was 28.4–30.4%. The WRT had acceptable precision, excellent linearity, and good association with the RIA.

“We Never Got to Try That Experience of Total Chaos”: Exploring Preservice Music Teachers’ Agency in Teaching Practicum
Authors: Bjørnevoll Silje Meling
Published: December 2022

The purpose of this instrumental case study was to investigate one single case of four preservice music teachers’ (PMTs) in their teaching practicums, carried out as a part of a Norwegian general teacher education program. The main data sources were based on material from three focus group interviews and observations from the PMT’s teaching practicums implemented at two practice schools for a total of five weeks. Emirbayer and Mische’s triadic conception of agency provided the theoretical framework for the analysis, highlighting temporal orientations (past, present, and future) of the actions. The findings revealed how the temporal dimensions of agency gave nuanced understandings of the PMT’s experiences of being supported (or limited) to make decisions and take actions in music teaching settings, either by the school-based mentors or themselves. The study underlines the importance of increased focus and inclusion of agency within teaching practicum contexts to prepare PMTs for future challenges.
Depression, Anxiety, and Posttraumatic Stress Disorder Following Intimate Partner Violence: The Role of Self-Criticism, Guilt, and Gender Beliefs
Authors: Naismith Iona , Ripoll-Nuñez Karen , Henao Gabriela Baquero
Published: December 2022

Intimate partner violence (IPV) predicts anxiety, depression, and posttraumatic stress disorder (PTSD), yet the role of cognition in these pathways is poorly understood. This study explored whether self-criticism, guilt, and gender beliefs predicted psychological symptoms, using self-report data from 50 Colombian female IPV survivors with diverse socioeconomic statuses. Self-criticism and guilt were high and significantly associated with IPV. Self-criticism significantly predicted depression and PTSD, whilst only guilt predicted anxiety. Traditional gender role beliefs were associated with emotional abuse, but not with self-criticism, guilt, or symptoms. In conclusion, self-criticism and guilt are important treatment targets for female IPV survivors, regardless of gender beliefs.

Published: December 2022

Introduction

Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) indicated for the treatment of epidermal growth factor receptor mutated non-small cell lung cancer (NSCLC). It has demonstrated better results concerning effectiveness than other TKIs for the same indication. However, despite a good safety profile, it could produce some cardiotoxicity that does not occur with other drugs of the same group.

Case report

We report the evolution and management of a female patient diagnosed with NSCLC who developed a grade 3 cardiotoxicity due to treatment with osimertinib. This patient suffered from a left bundle branch block, dyslipidemia, and hypertension as cardiovascular risk factors. After a long period of treatment with osimertinib, she developed a severe heart failure (HF) with an important decrease in left ventricular ejection fraction (LVEF), which triggered an admission to the oncology unit for eight days.

Management and outcomes

Treatment with osimertinib was first suspended and then resumed after stabilization of the HF. She also developed atrial fibrillation during admission and has required narrow cardiac monitoring and management since the debut of the HF. After evaluating the benefit-risk balance, osimertinib was reintroduced and the patient continues in treatment at the moment, although the baseline LVEF is not recovered.

Discussion

There is scarce evidence in the literature concerning HF and important LVEF decrease due to osimertinib. However, its severity and repercussion for the patient justify the thorough screening of cardiovascular risk factors before starting the therapy.
Climate Change is an Emerging Threat to Perinatal Mental Health
Authors: Barkin Jennifer L. , Philipsborn Rebecca P. , Curry Carolann L. , Upadhyay Saswati , Geller Pamela A. , Pardon Madelyn , Dimmock James , Bridges Christy C. , Sikes Christina A. , Kondracki Anthony J. , Buoli Massimiliano
Published: December 2022

Objective:

In this discussion, we build the case for why climate change is an emerging threat to perinatal mental health.

Method:

A search of current literature on perinatal and maternal mental health and extreme weather events was conducted in PubMed/MEDLINE and Web of Science databases. Only articles focusing on maternal mental health were included in this narrative review.

Results:

The perinatal period represents a potentially challenging timeframe for women for several reasons. Necessary role adjustments (reprioritization), changes in one’s ability to access pre-birth levels (and types) of social support, fluctuating hormones, changes in body shape, and possible complications during pregnancy, childbirth, or postpartum are just a few of the factors that can impact perinatal mental health. Trauma is also a risk factor for negative mood symptoms and can be experienced as the result of many different types of events, including exposure to extreme weather/natural disasters.

Conclusion:

While the concepts of “eco-anxiety,” “climate despair,” and “climate anxiety” have garnered attention in the mainstream media, there is little to no discussion of how the climate crisis impacts maternal mental health. This is an important omission as the mother’s mental health impacts the family unit as a whole.
Teacher and Emergent Bilingual Student Read-Aloud Mediations
Authors: Bakhoda Iman , Christ Tanya , Chiu Ming Ming , Cho Hyonsuk , Liu Yu
Published: December 2022

We explored (a) emergent bilingual students’ talk-turns during read-alouds, (b) how earlier talk-turns were related to later talk-turns, and (c) how talk-turns varied across more versus less culturally relevant books. One teacher and her four students’ read-alouds across two sessions each were video-recorded and transcribed. Emergent coding was used to identify talk-turn codes. Codes were categorized using Zone Theory constructs (Zone of Free Movement, Zone of Promoted Action, Zone of Proximal Development, Zone of Actual Development). Statistical discourse analysis showed that several Zone of Free Movement mediations (book/lesson/off-task) predicted comprehension talk-turns (developed connections/comparisons/contrasts). Zone of Promoted Action mediations predicted subsequent talk-turns: (a) reiteration/modeling were related to children expressing developed factual knowledge, (b) clarification/extension were related to children expressing developed opinions, (c) clarification/agreement were related to children expressing developed inferences, and (d) 11 talk-turns supported children expressing vocabulary knowledge.
“SAME GURL”: Political Feeling in LGBTQ+ Digital Composing
Authors: Shrodes Addie
Published: December 2022

Through a study of digital composing in LGBTQ+ YouTube reaction video channels, I explore the role of emotion in shaping how writers in virtual communities collectively feel about injustice and write for social change. In the reaction videos, vloggers circulate funny, emotional reactions to anti-LGBTQ+ media undergirded by oppressive ideologies and norms. To guide the analysis, I draw on queer and Black feminist theories to conceptualize political feeling as cultural formations of emotions that shape how a community feels toward injustice and open or foreclose possibilities for movement toward social change. By constructing and analyzing composing events situated in a virtual ethnography, I find reaction videos construct and circulate the political feeling of radical joy, or willful and resistant happiness in the face of oppression. Radical joy, then, mediates the satirical critiques of interlocking structures of power and the development of belonging in struggles for liberation in the comment section.
Decreasing trend of inpatient mortality rates of aseptic versus septic revision total hip arthroplasty: an analysis of 681,034 cases
Authors: Ng Mitchell K , Kobryn Andriy , Emara Ahmed K , Krebs Viktor E , Mont Michael A , Piuzzi Nicolas S
Published: December 2022

Background:

While most revision total hip arthroplasties (rTHAs) are for aseptic loosening/instability, infection accounts for approximately 16%. The purpose of this study was to: (1) quantify mortality rates of aseptic versus septic rTHA; (2) determine if mortality rates have changed over the past 20 years; and (3) identify associated preoperative risk factors, focusing on the utility/validity of the Elixhauser comorbidity index (ECI).

Methods:

ICD-9/ICD-10 codes were used to identify patients undergoing rTHA in the National Inpatient Sample database between 1998 and 2017. A total of 681,034 cases (576,143 aseptic THA and 104,891 septic THA) were identified. For each patient, demographic variables including age, sex, race, insurance type, ECI, and inhospital mortality were gathered. A logistic regression model was constructed to assess risk of inhospital mortality.

Results:

From 1998 to 2017, inpatient mortality rates of aseptic and septic rTHA decreased from 0.83 to 0.45%, and from 2.58 to 1.24%, respectively. Septic rTHA was independently associated with higher odds of mortality relative to aseptic (odds ratio (OR): 2.305, 95% confidence interval (CI): (2.014, 2.638), p < 0.0001). Increased ECI was associated with higher odds of mortality at both medium (OR: 5.147, 95% CI: (4.433,5.977), p < 0.0001) and high index scores (OR: 13.714, 95% CI: (11.519,16.326), p < 0.0001).

Conclusions:

Mortality rates for both aseptic and septic rTHA have been declining over the past 20 years, potentially due to patient selection guidelines and advances in medical management. Our study confirms that the ECI is independently associated with increased inpatient mortality.
Scaling up and scaling down: Improvisational handling of critical work practices during the COVID-19 pandemic
Authors: Berglund Martina , Harlin Ulrika , Elg Mattias , Wallo Andreas
Published: December 2022

The aim of this article is to explore improvisational handling of critical work practices during the COVID-19 pandemic and interpret these practices from a learning perspective. Based on an interview study with representatives of private, public and intermediary organisations, the study identified three different types of improvisational handling as responses to the pandemic crisis involving ‘scaling up’ and ‘scaling down’ critical work practices. By ‘scaling up’ and ‘scaling down’, we refer to practices for which, due to the pandemic, it has been imperative to urgently scale up an existing operational process or develop a new process, and alternatively extensively scale down or cease an existing process. The types of improvisational handling differed depending on the discretion of involved actors in terms of the extent to which the tasks, methods and/or results were given beforehand. These types of improvisational handling resulted in temporary solutions that may become permanent after the pandemic. The framework and model proposed in the article can be used as a tool to analyse and learn from the changes in work practices that have been set in motion during the pandemic. Such learning may improve the ability to cope with future extensive crises and other rapid change situations.
Ritual as metaphor
Authors: Della Costa Francesco
Published: December 2022

The effectiveness of ritual is a major anthropological question. In this paper, I challenge some of the explanations anthropologists have provided to such a question and I attempt to formulate an original theorization of ritual as metaphor. The proposed hypothesis is grounded in two inspiring concepts: Ernesto De Martino's idea of “dehistorification” as the main technique of the ritual and Bruce Kapferer's “virtuality” as its proper dynamic dimension. Drawing on these theoretical foundations and a direct ethnographic experience and conceiving of ritual as a practice rather than as a symbol, I propose to regard it as a particular practice of metaphorization that is not representative of reality but effective on it.
Political animosity: A novel theoretical framework
Authors: Abraham Villy , Shaked Ohad
Published: December 2022

A growing body of research points to the influence of animosity in general and political animosity in particular (henceforth referred to as PA) on tourism behavior. However, past research overlooked the role of perceived intergroup threat (henceforth referred to as PIT) and trust in the context of PA. This research note challenges previous theoretical frameworks designed to elucidate animosity as a consumer phenomenon. Preliminary research findings suggest PIT, tourist trust, and overall destination image (henceforth referred to as ODI) are salient constructs accounting for a substantial proportion of explained variances in the proposed model. Initial analyses of the research data suggest that PA is more strongly associated with trust than willingness to travel (henceforth referred to as WTT). Furthermore, ODI partly mediates the relationship between PA and WTT. Several practical implications are suggested to assist intermediate to high-ranking administrators in the industry mitigate the effect of the health crisis on their companies.

Published: December 2022

The development of medical device technology has led to the rapid growth of medical imaging data. The reconstruction from two-dimensional images to three-dimensional volume visualization not only shows the location and shape of lesions from multiple views but also provides intuitive simulation for surgical treatment. However, the three-dimensional reconstruction process requires the high performance execution of image data acquisition and reconstruction algorithms, which limits the application to equipments with limited resources. Therefore, it is difficult to apply on many online scenarios, and mobile devices cannot meet high-performance hardware and software requirements. This paper proposes an online medical image rendering and real-time three-dimensional (3D) visualization method based on Web Graphics Library (WebGL). This method is based on a four-tier client-server architecture and uses the method of medical image data synchronization to reconstruct at both sides of the client and the server. The reconstruction method is designed to achieve the dual requirements of reconstruction speed and quality. The real-time 3D reconstruction visualization of large-scale medical images is tested in real environments. During the interaction with the reconstruction model, users can obtain the reconstructed results in real-time and observe and analyze it from all angles. The proposed four-tier client-server architecture will provide instant visual feedback and interactive information for many medical practitioners in collaborative therapy and tele-medicine applications. The experiments also show that the method of online 3D image reconstruction is applied in clinical practice on large scale image data while maintaining high reconstruction speed and quality.
Ambivalent thinking amid pandemic biopolitics
Authors: Hall Chris
Published: December 2022

This review article surveys recent work in political theory that has brought together biopolitics and the COVID-19 pandemic. Centered on 2021 books by Giorgio Agamben and Benjamin Bratton, the essay outlines prominent visions of “negative” (Agamben) and “positive” (Bratton) biopolitical responses to the pandemic, engages public reactions to these approaches, and reassesses the position of biopolitical thinking in light of these. In doing so, the article recalls the foundations and original interventions of biopolitical theory, calling for a renewed engagement with the perspectives afforded by biopolitics that pushes past the negative/positive binary. Ultimately, the essay gathers together major developments in biopolitical thinking today, counters moves to discard the theoretical approach despite the limitations of recent examples, and repositions biopolitics as an ambivalent tool for political thought and practice going forward.
Data quality evaluation for bridge structural health monitoring based on deep learning and frequency-domain information

Abnormal data recognition is of great importance in structural health monitoring. Most of the existing studies focused on detecting obvious abnormal data, which has obvious abnormal time-domain waveform. Pseudo normal data, which is normally looking in time domain but chaotic in frequency domain, did not receive enough attention and were likely to be misclassified as normal data. As a result, structural performance may be incorrectly evaluated because pseudo normal data are not recognized and eliminated from the monitoring data. This study developed a novel quality evaluation framework for monitoring data of bridge dynamic response. The main novelty of the proposed framework is that the frequency-domain information is used to characterize the quality of the monitoring data so that the normal data, obvious abnormal data, and pseudo normal data can be accurately distinguished. In the framework, the frequency-domain information was obtained by fast Fourier transform (FFT), and the Gramian angular field images converted from FFT results were used to train a designed convolutional neural network (CNN). The cable acceleration data of the Waitan cable-stayed bridge were taken as an example to verify the accuracy of the proposed framework. Compared with the CNN models based on time-domain images and time-frequency stacked images, this framework can better recognize pseudo normal data from the monitoring data. In large-scale testing, the classification accuracy of all channels was more than 96%. Finally, two cable acceleration sensors of another cable-stayed bridge were used to demonstrate the feasibility of the framework in cross-object application. The results show that the framework has good accuracy and robustness in large-scale monitoring data quality evaluation and cross-object application.
Trauma drama: The trouble with competitive victimhood
Authors: Taylor Robert S.
Published: December 2022

Writing a college-application essay has become a rite of passage for high-school seniors in the United States, one whose importance has expanded over time due to an increasingly competitive admissions process. Various commentators have noted the disturbing evolution of these essays over the years, with an ever-greater emphasis placed on obstacles overcome and traumas survived. How have we gotten to the point where college-application essays are all too frequently competitive-victimhood displays? Colleges have an understandable interest in the disadvantages their applicants may have suffered, but this interest – and the awareness of it among both applicants and their advisors – has led to a ‘race to the bottom’: in order to thrive (or even survive) in a particular competitive context, participants are forced to continuously lower relevant standards in a game of one-upmanship. With college essays, the competition is among high-school seniors for admission, the one-upmanship is an ever-escalating effort to persuade admission committees of one’s greater disadvantage, and the relevant standards being lowered are honesty, privacy, and dignity – or so I shall argue. As we will see, this particular race to the bottom imposes unequal costs on certain groups and has implications stretching well beyond collegiate admissions.
The broad and the narrow account of education – A false dichotomy? Marley-Payne’s suggestion for amelioration of the concept of education
Authors: Norefalk Christian
Published: December 2022

In his article ‘An Ameliorative Analysis of the Concept of Education’, Jack Marley-Payne sets out to provide an ameliorative analysis of the concept ‘education’. Marley-Payne draws an important distinction between what he labels the ‘Broad’ and the ‘Narrow’ account of education. His conclusion is that an ameliorative conceptual analysis of education favours the narrow account. The main argument is that a narrow approach, tightly connected to formal schooling, provides a better basis for pursuing an egalitarian agenda. Contrary to Marley-Payne, I will argue that an amelioration of the concept education need not favour either a wide notion or a narrow notion. I believe that there are other alternatives to choose from, that in fact leads to an amelioration of what education can and ought to mean. The problem with Marley-Payne’s conclusion is thus, not only that it builds upon a false dichotomy but also that it is not emancipatory enough. We need an amelioration that is inclusive rather than exclusive.
Exploring the Relationship between Nurse Practitioner Full Practice Authority, Nurse Practitioner Workforce Diversity, and Disparate Primary Care Access

In this study, we examine how full nurse practitioner (NP) practice authority affects racial and ethnic diversity of the NP workforce. Specifically, the purpose of our research is to understand the relationship between the racial and ethnic composition of the NP workforce, NP level of practice authority, and the communities they service. In this paper, we compare the ethnic and racial composition of the NP workforce to the composition of the state's population, and then observe if there are any noticeable differences in the patients served by NPs when we compare full practice authority (FPA) and non-FPA states. We also estimate how FPA affects the race and ethnicity of Medicare patients served by NPs.
Exploring the Virtual Culture of Reality Television Communities: Lessons From #Date My Family
Authors: Ngcongo Mthobeli
Published: December 2022

The socio-technological affordances of Twitter have steadily enabled audiences of reality television shows to form virtual communities through the use of hashtags to organize and share commentary about their favorite shows. Although the communication activities around hashtag communities are becoming more apparent, research on mapping their online cultures remains underappreciated. Scholarly work is needed that makes the links between culture and communication more apparent, thereby enhancing our understanding of virtual communities formed around interest in reality television. Using a small-scale sample of tweets ( n = 203) from season eight of the reality dating show Date My Family, I explore what the cultural expressions of the South African #Datemyfamily virtual community entail. A thematic analysis suggests that values, norms, beliefs, attitudes, and behaviors constitute a strong cultural part of what is communicated by the #Datemyfamily community. Ultimately, the virtual culture of this online group places emphasis on solidifying the community’s imagined collective consciousness.

Acute interstitial nephritis (AIN) is a relevant cause of acute renal failure. Drugs are the predominant cause, followed by infections and idiopathic lesions. AIN, as a form of hypersensitivity reaction, is an uncommon manifestation in the setting of human parasitic infections. We report a case of a polyparasitic infection ( Giardia lamblia, Entamoeba coli, and Endolimax nana) resulting in a severe biopsy-proven AIN in a 61-year-old male patient. Despite the antiparasitic treatment followed by corticosteroid therapy, and during the 6-month follow-up period, the patient remained dialysis-dependent, and he developed autoimmune hemolytic anemia. Extensive search for another infection or neoplasia was negative. Immunological tests were also negative. The resulting hypersensitivity reaction to the triple parasite infection would have led to fatal evolution for the kidneys affected by this unusual type of AIN.
