Clinical characteristics and laparoscopic surgical outcomes of ovarian dermoid cysts complicated by spontaneous rupture: nine cases and a literature review
Authors: Takeda Akihiro , Koike Wataru
Published: May 2023

Objective

To clarify the clinical characteristics and laparoscopic surgical outcomes of dermoid cysts complicated by spontaneous rupture.

Methods

This was a single-center retrospective observational study of patients with dermoid cysts treated between January 2005 and December 2021.

Results

Among 1205 cases of dermoid cysts, spontaneous rupture occurred in nine and torsion occurred in 83 cases. No obvious triggers for rupture were identified, except for one postpartum case with fundal uterine pressure maneuver. Rupture was identified by computed tomography (CT) in six cases. Patients with ruptured cysts had significantly higher serum C-reactive protein (CRP), cancer antigen 125 (CA125), carbohydrate antigen 19-9 (CA19-9), and squamous cell carcinoma antigen (SCC) levels compared with patients with uncomplicated dermoid cysts or cysts with torsion. Laparoscopic management was possible except for one case with severe adhesion, which required laparotomy. Two patients required prolonged postoperative administration of antibiotics due to refractory chemical peritonitis.

Conclusion

Combined use of CT imaging and elevated levels of CRP, CA125, CA19-9, and SCC may help to differentiate cyst rupture from torsion. Laparoscopic surgery may be a feasible option; however, prompt laparotomic conversion should be considered in cases with difficult adhesiolysis. Refractory chemical peritonitis may occur after successful surgical management.

Authors: Chen Shih-Pin , Takizawa Tsubasa , Sekiguchi Koji , Nakahara Jin , Wang Shuu-Jiun
Published: May 2023

Background

Recent pharmacovigilance studies suggested that cluster headache could be a potential adverse effect after coronavirus disease-2019 (COVID-19) vaccination; however, the possibility of coincidence could not be excluded. Detailed case studies might help elucidate their potential link and implicate potential pathogenic mechanisms.

Methods

Patients who developed cluster headache in close temporal relationship to COVID-19 vaccination were identified from two tertiary medical centers in Japan and Taiwan respectively through 2021–2022. Detailed characteristics of the headaches and time between the onset of the index cluster episode and antecedent COVID-19 vaccination were reported. In patients with previous cluster headaches, the duration from previous bout was also recorded.

Results

Six patients with new cluster headache bout 3–17 days after COVID-19 vaccination were identified. Two of them were de novo cases. The others either had been attack-free for a long time or developed new cluster bout in seasons atypical to prior bouts. The vaccines included mRNA, viral vector, or protein subunit vaccines.

Conclusions

COVID-19 vaccines, regardless of vaccine types, may elicit de novo or relapse of cluster headache. Future studies are needed to confirm the potential causality and explore the potential pathogenic mechanism.
Increasing the Reliability of Formation Factor-Based Transport Property Prediction for High Performance Concrete Mixtures Through Innovative Matching Pore Solution Curing
Authors: Saraswatula Pravin , Mukhopadhyay Anol
Published: May 2023

Recent specifications for concrete bulk resistivity tests (ASTM C 1876 and AASHTO TP 119) recommend a submerged standard (simulated) pore solution (SPS, solution conductivity = 78.74 mS/cm) for curing concrete specimens. The rationale for the bucket test is that immersing concrete specimens in a soak solution similar to their pore solution would eliminate the need to determine pore solution resistivity for calculating the formation factor (FF) of concrete mixtures. However, the thermodynamic modeling predictions of 91-day pore solution concentration (PSC) for eight high performance concrete (HPC) mixtures evaluated in the current study showed SPS to be a close representation only for reference ordinary Portland cement (OPC) and binary silica fume mixtures. In contrast, the average PSC of Class F and Class C fly ash mixtures was approximately 12% to 20% lower and 20% to 40% higher, respectively, than the SPS. Accordingly, an innovative matching pore solution (MPS) curing approach was developed in which mixtures are grouped based on the influence of supplementary cementitious materials (SCMs), that is, their type and replacement levels of the long-term PSC of concrete mixtures and, thereby, cured in a simulated solution matching the average PSC of a particular group. Based on experimental work in the current study, HPC mixtures under MPS demonstrated a lower coefficient of variation (COV) and more comparable (<10% difference) bulk resistivity (BR) and surface resistivity (SR) measurements compared with SPS. Moreover, the MPS improved the reliability in FF determination and FF-based transport property prediction for HPC mixtures, as verified by lower mean absolute error and improved R2 between FF-predicted diffusion coefficients and experimental measurements.
Impact of the COVID-19 Vaccination on Bike Sharing Demand in NYC: ARIMAX and Bayesian Time Series Analyses
Authors: Drummond Justin , Hasnine Md Sami
Published: May 2023

The objective of this study is to investigate the impact of the COVID-19 vaccine on bike sharing demand in New York City (NYC). The vaccination’s impact was also compared with other known influences (COVID-19 cases counts, COVID-19 deaths, weather data, trip purpose, and more) to help improve bike share demand modeling in a pandemic setting. Autoregressive integrated moving average (ARIMAX) time series models were estimated for Brooklyn and Manhattan in both the pre-vaccine and post-vaccine periods. Mean absolute percentage error (MAPE) was used for model evaluation, and the average MAPE was below 5, suggesting a high-level accuracy in modeling. The Bayesian time series analysis results were very similar to the ARIMAX model results (with the exception of some parameters being significantly underestimated). The results of the time series analyses showed that vaccination did not have a significant effect on bike sharing demand in Manhattan but had a significant effect leading to increases in bike sharing demand in Brooklyn. Despite this, vaccination was not the main influence on bike sharing demand. For instance, in Brooklyn, grocery and retail/recreational shopping were strong influences both pre- and post-vaccine, indicating that regardless of vaccination, shopping is essential. COVID-19 cases counts had opposing effects in Brooklyn and Manhattan. Other findings include higher temperatures leading to increased bike demand, and precipitation and stronger winds leading to decreased bike sharing demand.
Flexible Pavement Resiliency and Mitigation Strategies Following Adverse Environmental Events
Authors: Tseng Ester , Al-Qadi Imad L. , Tutumluer Erol , Qamhia Issam I. A. , Ozer Hasan
Published: May 2023

Water accelerates flexible pavement damage in various ways, including subgrade and granular pavement materials strength reduction, frost heave, swelling of expansive subgrade soils, and asphalt binder stripping of aggregate in asphalt concrete (AC) mixes. This paper presents case studies of AC pavement sections in the U.S. that withstood high moisture events with limited effect on pavement performance and no immediate need for major maintenance or rehabilitation actions. The case studies comprise pavement sections in Florida and Louisiana that were subjected to catastrophic flooding events, a pavement section in Delaware that is constantly exposed to tidal water level variations, and pavement sections in Montana and Minnesota that experience seasonal freeze-thaw. These cases illustrated that flexible pavements could withstand climatic changes when appropriately designed and constructed. Mechanically or chemically stabilized subgrade, proper drainage, and/or minimizing plastic fines in unbound layers are all techniques that could effectively control moisture damage.
Characterizing Behavioral Differences of Autonomous Vehicles and Human-Driven Vehicles at Signalized Intersections Based on Waymo Open Dataset
Authors: Wang Yiyun , Farah Haneen , Yu Rongjie , Qiu Shuhan , van Arem Bart
Published: May 2023

Autonomous vehicles (AVs) are being introduced to the traffic system with the promise of improving current traffic status. However, the empirical data also indicate contrary effects with estimated higher crash rate and change of crash patterns. Therefore, it is necessary to investigate the driving behavior of AVs and human-driven vehicles (HDVs) in real mixed traffic. Current studies have analyzed the driving behavior of AVs and HDVs, as well as behavioral adaptations of drivers of HDVs based on empirical data. While they play an important role in traffic systems, signalized intersections have not been studied sufficiently in this context. Therefore, this study aims to utilize the Waymo open dataset to characterize and quantify the behavioral differences of AVs and HDVs at signalized intersections. Five parameters of driving behavior related to signalized intersections were characterized according to five critical maneuver phases, which were identified by wavelet transform and threshold-based method. Statistically significant differences in driving behavior between AVs and HDVs were found, from three categorized situations: vehicle approaching the red light/queue, vehicle responding to the green light (as the first vehicle), and vehicle responding to its preceding vehicle (in the queue). Further, behavioral adaptations of HDV drivers were revealed in that they tended to keep closer to the stopped AVs in a queue and to react more strongly to AV start-up maneuvers when the traffic light turns to green.
Evaluation of Crack Development Through a Bituminous Interface Reinforced With Geosynthetic Materials by Using a Novel Approach
Authors: Solatiyan Ehsan , Ho Van Thang , Bueche Nicolas , Vaillancourt Michel , Carter Alan
Published: May 2023

Using interlayers made of geosynthetic materials has proved its effectiveness with respect to postponing the appearance of reflective cracking on the surface. In this regard, in a reinforced bituminous interface, the crack first propagates from its origin upward until it reaches the interlayer. When the interlayer has higher stiffness than its surrounding bituminous material, the crack path diverts horizontally along the interlayer plane until the whole energy of the crack dissipates. Nevertheless, this mechanical improvement needs to be further studied to quantify the reinforcement effects of geosynthetic materials in mechanistic-based design of reinforced sections. This study aimed to develop a laboratory test method that not only is able to illuminate the crack resistance effect of geosynthetics but is also able to differentiate the load–displacement curves among different types of reinforced bituminous interfaces. The results led to the advent of a new test device called the crack widening device in which reproducibility and statistical variability of the outcomes were all within the acceptable range. On this ground, using paving fabric showed superior performance among others with respect to energy dissipation capability and retarding the loss in the stiffness modulus during the crack propagation stage compared with the corresponding unreinforced cases. On the other hand, using the reinforcement grids led to a higher initial stiffness of the reinforced structure, especially when embedded between coarse hot mixtures.
Public Transit Itinerary Choice Analysis Considering Various Incentives
Authors: Pan Long , Waygood E.O.D. , Patterson Zachary
Published: May 2023

Previous research on public transport user preferences has primarily focused on mode choice, transfer penalties, and preferences related to service qualities. Individuals are generally found to not like waiting, transfers, or overcrowding. However, from an operation perspective, it could be important to convince users to change to a different itinerary to reduce overcrowding, which can cause problems such as bunching. This would most likely require convincing the user to voluntarily accept a longer wait or to take a different route potentially with a transfer. One means of doing so might be through incentives or offering a shared taxi. Incentivizing transit users to switch to a less-crowded itinerary, which could potentially be a way to manage bus overcrowding, is not well-studied. Through a discrete choice experiment, this study thus filled this research gap by testing people’s willingness to change routes or to take a shared taxi in exchange for one of three distinct types of incentives. A mixed binary logit model and a mixed nested logit model were used to investigate how different factors influence public transit user itinerary choice behavior. The results suggested that some people would be willing to change to the proposed alternative. Heterogeneity within the responses was seen as transit users were found to have distinct preferences for different incentives, and the value of the incentives influenced users differently. Our models and results could be helpful for public transit agencies to improve efficiency and reduce costs by better balancing the travel demand.
Investigating the Seepage Characteristics of an Open-Graded Friction Course Using Finite Element Modeling
Authors: Abohamer Hossam , Elseifi Mostafa A. , Mayeux Corey , Cooper Samuel B. , Cooper Samuel
Published: May 2023

An open-graded friction course (OGFC) is an asphalt mixture designed with a large air void (AV) content that provides enhanced drainage capability at the surface. The main objectives of this study were to investigate the impacts of selected factors (i.e., the OGFC thickness and coefficient of permeability, the permeability of the underlying layer, and traffic loading) on the drainage characteristics of the OGFC, develop a quantitative tool to simulate the deterioration in the functional performance of the OGFC, and propose new guidelines for the AV content of OGFC for optimum functionality. To this end, a three-dimensional finite element (FE) model was developed to evaluate the impacts of OGFC permeability, OGFC layer thickness, underlying layer permeability, rain intensity, and traffic volume on the seepage characteristics of OGFC pavements. The impacts of these factors were evaluated by calculating the time at which the OGFC surface reaches overflow condition ( TC). Statistical analysis of the results showed that all considered factors had a significant impact on OGFC seepage characteristics, except OGFC permeability. In addition, an artificial neural network (ANN) model was developed to predict TC without the need for FE modeling. Results indicated that the ANN model predicted TC accurately with R2 values of 0.99 and 0.98 in the training and validation stages, respectively. The results also indicated that the model accurately predicted TC over time for OGFC pavements with a root-mean-square error of less than 5.0%. Simulation runs were conducted using the developed FE model under different OGFC AV content conditions and rain intensities. Results revealed that an OGFC layer with an AV content of 16% would provide adequate drainage performance while minimizing OGFC durability issues.
Impact of Restricted Crossing U-Turns on Vehicular Emissions
Authors: Guin Angshuman , Robinson Kyle , Unthank Haley , Roy Somdut , Hunter Michael
Published: May 2023

In recent years, several innovative intersections have been designed and implemented as an alternative to typical two-way intersections. The Restricted Crossing U-Turn (RCUT) is a type of innovative intersection design that limits left-turns from the minor road by directing cross-street traffic to one of two auxiliary U-turns. This design seeks to improve intersection safety by reducing conflict points, as well as increase the capacity and decrease travel time on certain movements, such as the mainline through traffic. However, the change in the cross-street vehicle paths through the intersection can affect acceleration profiles and emissions. This research develops a methodology to test emission differences through simulation. Models of an RCUT and a traditional intersection were constructed and tested under varying turn volumes and mainline speeds conditions. CO2 and NOx emissions were calculated using Vissim simulation vehicle trajectories and the Motor Vehicle Emissions Simulator (MOVES) model. The modeled emissions values were used to compare the overall emissions performance of the RCUT versus a traditional intersection layout. The RCUT intersection layout was associated with an increase in average cross-street through and left-turn movement emissions because of the longer travel distances. However, a reduction in emissions was seen on the main line, primarily as a result of the additional green-time afforded by the RCUT design. Where the mainline volume to side-street ratio becomes sufficiently large, the RCUT performed better in overall intersection emissions levels.
Research on Predatory Publishing in Health Care: A Scoping Review
Authors: Oermann Marilyn H. , Waldrop Julee , Nicoll Leslie H. , Peterson Gabriel M. , Drabish Kerry Simmons , Carter-Templeton Heather , Owens Jacqueline K. , Moorman Teresa , Webb Bridget , Wrigley Jordan
Published: May 2023

Background

Predatory publishers and their associated journals have been identified as a threat to the integrity of the scientific literature. Research on the phenomenon of predatory publishing in health care remains unquantified.

Purpose

To identify the characteristics of empirical studies on predatory publishing in the health care literature.

Methods

A scoping review was done using PubMed/MEDLINE, CINAHL, and Scopus databases. A total of 4967 articles were initially screened; 77 articles reporting empirical findings were ultimately reviewed.

Results

The 77 articles were predominantly bibliometric analyses/document analyses (n = 56). The majority were in medicine (n = 31, 40%) or were multidisciplinary (n = 26, 34%); 11 studies were in nursing. Most studies reported that articles published in predatory journals were of lower quality than those published in more reputable journals. In nursing, the research confirmed that articles in predatory journals were being cited in legitimate nursing journals, thereby spreading information that may not be credible through the literature.

Conclusion

The purposes of the evaluated studies were similar: to understand the characteristics and extent of the problem of predatory publishing. Although literature about predatory publishing is abundant, empirical studies in health care are limited. The findings suggest that individual vigilance alone will not be enough to address this problem in the scholarly literature. Institutional policy and technical protections are also necessary to mitigate erosion of the scientific literature in health care.
Lactation Induction in a Transgender Woman: Macronutrient Analysis and Patient Perspectives
Authors: Weimer Amy K.
Published: May 2023

Introduction

Induction of lactation in a non-gestational parent has numerous potential benefits including parent–child bonding, optimal nutrition, and health benefits to the child and breast- or chest-feeding parent. For transgender women and nonbinary people on estrogen-based, gender-affirming hormone therapy, the ability to nourish their infants through production of their own milk may also be a profoundly gender-affirming experience. Two prior case studies have been published describing induced lactation in transgender women, but analysis of the nutritional quality of the milk produced has not been previously described.

Main issue

Here we describe the experience of a transgender woman who underwent successful induction of lactation in order to breastfeed her infant, who was gestated by her partner.

Management

Through modification of exogenous hormone therapy, use of domperidone as a galactogogue, breast pumping, and ultimately direct breastfeeding, the participant was able to co-feed her infant for the first 4 months of life. We provide a detailed description and timeline of the medications used, laboratory and electrocardiographic measurements, results of the participant’s milk analysis showing robust macronutrient content, and description of the participant’s experience in her own words.

Conclusion

These findings provide reassurance about the adequacy of nutrition from human milk produced by non-gestational transgender female and nonbinary parents on estrogen-based, gender-affirming hormone therapy, and support the importance of this experience on a personal level.
Spring-in behavior of woven carbon fiber/polycarbonate thermoplastic composites
Authors: Hwang Shun-Fa , Yu Cheng-Xuan
Published: May 2023

The spring-in behavior of woven carbon fiber/polycarbonate thermoplastic composite is investigated by both the experiment and simulation ways. These thermoplastic composite plates are thermoformed into V-shaped structures, and the final bending angle is measured after demolding. In the finite element simulation to describe the thermoforming and spring-in behavior of the composite, the discrete approach is adopted to simulate the behavior of woven carbon fabric and combined with a resin model. The results from both the experiment and the simulation indicate the spring-in behavior of this thermoplastic composite. For [(±45)]6 blanks, the spring-in angle is around 2.60° for a 60-degree V-shape and around 1.72° for a 90-degree V-shape. For [(0/90)]6 blanks, the spring-in angle is around 2.38° and 1.19° for 60-degree and 90-degree V-shapes, respectively. The [(±45)]6 blank always has a slightly higher spring-in angle than the [(0/90)]6 blank, even though the difference is small. The finite element results show 6% to 12% differences with the experimental values if the spring-in angle is used, and the error is less than 0.6% when the bending angle is compared. By using the present finite element analysis, the results indicate that the stacking sequence could have an evident effect on the spring-in angle, and symmetric laminates have less spring-in effect as compared to their unsymmetric counterparts.
Mind the Like-Minded. The Role of Social Identity in Prosocial Crowdfunding
Authors: Monik Anna , Parzuchowski Michał
Published: May 2023

Current social challenges have increased the interest in globally spread collective actions, especially those taking place in virtual space. Crowdfunding is one form of online activism that has recently gained importance. Although research conducted so far indicates the significance of social motives among participants of crowdfunding campaigns, knowledge about the psychosocial mechanisms involved in its effectiveness is limited. This article attempts to reinforce the position of crowdfunding as one of the forms of collective action and to expand knowledge about possible psychosocial factors that could shape participation in crowdfunding campaigns. In three pre-registered studies ( N = 823), we found that the social identity based on a shared worldview positively correlated with the intention to participate in prosocial crowdfunding. Moreover, the relationship between opinion-based group identity and collective action varied depending on participation type (predicted vs. experienced engagement in a campaign). In other words, when people gather in communities built around shared opinions on a given social issue, they develop a sense of community, which can translate into activities for the benefit of the group such as supporting crowdfunding campaigns. However, in the case of actual behaviour, unlike with the declaration of participation, the strength of the relationship with social identity significantly diminishes. The results are discussed in relation to the theory of collective action.
Time Path of Weight Status Before and After Incident Dementia
Authors: Zhang Yuan S. , Chang Virginia W.
Published: May 2023

Objectives: Identifying whether obesity is a risk factor for dementia is complicated by the possibility of weight change as dementia evolves. This article investigates an extended time path of body mass index (BMI) before and after incident dementia in a nationally representative sample. Methods: Using the Health and Retirement Study (2000–2016), we examine (1) the longitudinal relationship between BMI and incident dementia and (2) heterogeneity in the BMI trajectory by initial BMI level. Results: Weight loss begins at least one decade before incident dementia, then accelerates in the years immediately preceding dementia onset and continues after incident dementia. Those with higher levels of BMI at baseline experienced a much greater decline relative to those with a normal weight. Discussion: Our results help explain the contradicting findings in the literature regarding the relationship between obesity and dementia and highlight the need for using extended longitudinal data to understand dementia risk.
Adaptive fast nonsingular terminal sliding mode tracking control for quadrotor with disturbances compensation and actuator saturation
Authors: Wei Hujie , Jiang Yan
Published: May 2023

This paper designs the double closed-loop control system combining nonlinear disturbances observers (NDOB) and an adaptive fast nonsingular terminal sliding mode (AFNTSM) for the tracking control problem of quadrotor under external disturbances, actuator saturation and unmodeled dynamics. The NDOB-AFNTSM method avoids the singularity problem. To compensate for disturbances, an adaptive strategy estimates the unknown bound of NDOB errors and the unknown bound of disturbances. Besides, new fast reaching law shortens convergence times. The dead zone method is chosen to avoid over-estimation and system divergence. Considering actuator saturation, this paper uses an anti-saturation auxiliary compensator to compensate for unknown saturation errors. System stability is confirmed by the Lyapunov direct method. The simulation results reveal that the proposed method improves convergence speed and accuracy, which is more robuster than similar methods. Finally, two comparative studies for performance indexes in simulation demonstrate the preferable performance of the proposed method.
‘Relatively civilized, relatively European’: Offence and online (de)normalization of media racism
Authors: Altahmazi Thulfiqar Hussein , Abid Raith Zeher
Published: May 2023

The paper explores the interplay of offence, (de)normalization and moral conflict triggered by media racism. The paper is premised on the assumption that public interventions to moral transgressions occasion moral conflicts in which transgressions can be (de)normalized through impoliteness, more specifically the acts of offence taking and causing. A YouTube video discussing the racist media coverage of the Ukrainian refugee crisis was analyzed along with a sizable amount of related user-generated comments. The analysis showed that offence taking and offence causing have morally restorative and (de)normalizing functions in moral conflict. This highlights the fact that the relationship between morality and impoliteness is much more complex than is usually theorized, wherein impoliteness is often perceived as a morally norm-disruptive behavior or a negatively valenced evaluation thereof. Not only can impoliteness be morally justified in moral conflicts, it can also be a necessary form of restorative public intervention. This necessitates greater attention to (de)normalization in (im)politeness theorizing.
The national nature of globalization and the global nature of nationalism: Historically and methodologically entangled
Authors: Billig Michael
Published: May 2023

It is often assumed that psychological globalization produces tolerant, cosmopolitan outlooks, which deglobalization is now replacing with intolerance and narrow nationalism. This article argues that nationalism and cosmopolitanism, rather than being simple opposites, are entangled historically and methodologically, and that the national nature of globalization and the global nature of nationalism need to be recognized. Historically, the period of globalization coincided with the formation of the world of nation-states. Methodologically, economic calculations of globalization assume a world of nation-states. Nationalism is not only global in its reach but national consciousness is entangled with international consciousness. This entanglement may not be apparent if nationalism is equated with its extreme forms, for nationalism has everyday forms in established states. This article shows how studies of cosmopolitanism can themselves take for granted the world of nation-states within their methodologies. There are some brief suggestions about how to study banal nationalism.
Revisioning psychology and deglobalisation: The case of Brexit
Authors: Stenner Paul , Andreouli Eleni
Published: May 2023

This article approaches the theme of the psychology of de/globalisation by taking up the example of Brexit as an historical conjuncture that hinges upon troublesome questions of sovereignty. Operating at the interface between history and psychology, and informed by liminality scholarship, the paper offers a broad genealogical sketch of three mutations in the semantics of sovereignty as a mode of power that implicates subjectivity. Theological (premodern), nationalist (modern), and neoliberal/economic (postmodern) variants share the mythical motif of absolute autonomy. An account of globalisation as the spatial spread of the events of an initially partial process across the whole of a global field offers a view of the psychological as a subjective field of intelligibility shaped by societal and political settings. Drawing upon data from a focus group study conducted just before the 2016 referendum, attention is given to the resurgence of the theme of sovereignty amongst ordinary people.
Sub-categories of moral distress among nurses: A descriptive longitudinal study
Authors: Morley Georgina , Bena James F , Morrison Shannon L , Albert Nancy M
Published: May 2023

Background

There is ongoing debate regarding how moral distress should be defined. Some scholars argue that the standard “narrow” definition overlooks morally relevant causes of distress, while others argue that broadening the definition of moral distress risks making measurement impractical. However, without measurement, the true extent of moral distress remains unknown.

Research aims

To explore the frequency and intensity of five sub-categorizations of moral distress, resources used, intention to leave, and turnover of nurses using a new survey instrument.

Research design

A mixed methods embedded design included a longitudinal, descriptive investigator-developed electronic survey with open-ended questions sent twice a week for 6 weeks. Analysis included descriptive and comparative statistics and content analysis of narrative data.

Participants

Registered nurses from four hospitals within one large healthcare system in Midwest United States.

Ethical considerations

IRB approval was obtained.

Results

246 participants completed the baseline survey, 80 participants provided data longitudinally for a minimum of 3 data points. At baseline, moral-conflict distress occurred with the highest frequency, followed by moral-constraint distress and moral-tension distress. By intensity, the most distressing sub-category was moral-tension distress, followed by “other” distress and moral-constraint distress. Longitudinally, when ranked by frequency, nurses experienced moral-conflict distress, moral-constraint distress, and moral-tension distress; by intensity, scores were highest for moral-tension distress, moral-uncertainty distress, and moral-constraint distress. Of available resources, participants spoke with colleagues and senior colleagues more frequently than using consultative services such as ethics consultation.

Conclusions

Nurses experienced distress related to a number of moral issues extending beyond the traditional understanding of moral distress (as occurring due to a constraint) suggesting that our understanding and measurement of moral distress should be broadened. Nurses frequently used peer support as their primary resource but it was only moderately helpful. Effective peer support for moral distress could be impactful. Future research on moral distress sub-categories is needed.
The Jason Roberts case: A second or subsequent appeal process to correct miscarriages of justice?
Authors: Chifflet Pascale , Rose Meribah
Published: May 2023

The first re-trial under the second or subsequent appeal provisions introduced into the Criminal Procedure Act 2009 (Vic) has recently concluded, resulting in the acquittal of Jason Roberts for the 1998 murders of two Victoria Police officers. This article traces the various stages in Roberts’ efforts to have his conviction overturned, raising questions about the efficacy of the different mechanisms available for redressing miscarriages of justice. Ultimately, while the second or subsequent appeal process can be considered a success for Roberts, significant barriers remain for other wrongfully convicted persons whose circumstances do not receive the attention of a powerful commission of inquiry such as IBAC.
Citation Data and Analysis: Limitations and Shortcomings
Authors: Worrall John L. , Cohn Ellen G.
Published: May 2023

As a means for measuring scholarly influence, citation analysis has several limitations and shortcomings. We first review the main sources of citation data (Web of Science, Scopus, Google Scholar, and information collected directly from reference lists) and discuss the shortcomings of each source. Next, we review five significant limitations of citation analysis as a methodology (academic over popular interest, various motivations for citing, manipulation potential, failure to account for author ordering, and citations only appearing in “indexed” journals). The issues we touch on set the stage for the remainder of the articles in this special issue.
The Experience of Pregnancy and Childbirth Overshadowed by Obstetric Violence and Structural Barriers of the Israeli Health System from the Perspective of Arab and Jewish Women
Authors: Alnabilsy Raghda , Sharon Dganit
Published: May 2023

The aim of this study was to give a voice to Arab and Jewish women in Israel who had suffered obstetric violence during various stages of fertility treatments, pregnancy, and childbirth and also to learn from the women about their experiences of obstetric violence subject to the barriers of the Israeli health system, and their recommendations of possible solutions. The study underlines the unique gender, social, and cultural context in Israel concerning pregnancy and childbirth, and was based on the feminist approach that strives to promote human rights, and eradicate phenomena of gender-related, patriarchal, and social structures. The study used a qualitative-constructivist methodology. Twenty semi-structured interviews with ten Arab women and ten Jewish women were thematically analyzed, and five main themes emerged: first, the women’s experience of becoming pregnant and pregnancy overshadowed by physical and emotional barriers from caregivers and the close environment; second, the women’s awareness of their bodies and needs during pregnancy dominated by the challenges of the health services; third, the women’s awareness of their bodies and needs during childbirth alongside incompatible expectations and nonattentive medical staff; fourth, the women’s descriptions of experiences and types of obstetric violence; and fifth, the women’s recommendations to eradicate obstetric violence.
A Large-Scale Study of Students’ E-Service-Learning Experiences and Outcomes During the Pandemic
Authors: Ngai Grace , Lau Ka-Hing , Kwan Kam-Por
Published: May 2023

Background: The COVID-19 pandemic resulted in strict social distancing and lockdown measures to contain the spread of the disease. These measures significantly impacted experiential pedagogies, including service-learning. Many teachers pivoted to e-service-learning. While past literature suggests that e-service-learning is as, or even more effective than, traditional service-learning, there are few large-scale comparative studies that support this claim. Purpose: Our study fills the research gap via a large-scale study into student e-service-learning experiences and outcomes during COVID-19. Methodology/Approach: The study examines learning outcomes of students taking e-service-learning subjects during the early stage of the pandemic, i.e., the 2020/21 academic year, in a Hong Kong university, and compares their learning experiences and gains with a similar group of students who studied the same subjects from 2014/15 to 2018/19. Findings/Conclusions: Results indicate that while e-service-learning is effective in enhancing students’ cognitive and civic learning, it is less effective than traditional service-learning in facilitating civic learning outcomes. Implications: Investigating students’ learning experiences suggests that the quality of reflection and interaction with the community, which are critical learning experience components, may have been impacted by online communication. These factors may have played a key role in influencing the effectiveness of e-service-learning compared to traditional service-learning.
Evaluation of an Association Between Enoxaparin Dose per Estimated Blood Volume and Clinically Relevant Bleeding in Low-Weight Trauma Patients
Authors: Carter Chris , Denny Kailey , Carver Thomas W. , Jung Benjamin , Rein Lisa , Peppard William J.
Published: May 2023

Background:

The optimal dosing for enoxaparin venous thromboembolism (VTE) prophylaxis in low-weight trauma patients is unknown. Estimated blood volume (EBV) has shown promise as a dose modifier.

Objective:

To characterize the association of enoxaparin dose per EBV with the prevalence of VTE and bleeding in low-weight trauma patients.

Methods:

This was a retrospective study of trauma patients admitted over a 4-year period. Included patients were adults weighing <60 kg who received a minimum of 3 consecutive doses of enoxaparin. The primary endpoint was a comparison of enoxaparin dose per EBV in patients experiencing bleeding and VTE. Secondary endpoints included comparisons of dose per body mass index (BMI) and total body weight (TBW) and the ability of dose per EBV to predict clinical endpoints. Subgroup analyses for patients weighing <50 kg were performed for all endpoints.

Results:

A total of 189 patients were included. Statistical comparisons for VTE were not performed because of low prevalence. The dose of enoxaparin per EBV was not statistically different between patients who did and did not bleed in all analyses. Doses per BMI and TBW were also not statistically different between the groups. In patients weighing <50 kg, numerically higher doses per EBV, BMI, and TBW were noted in patients that bled versus those that did not. Enoxaparin dose per EBV was not a statistically significant predictor of bleeding in logistic regression models.

Conclusion and Relevance:

No significant associations between enoxaparin dose per EBV, BMI, or TBW and bleeding were noted in the study. Future analyses of EBV and other dose modifiers should consider inclusion of patients weighing <50 kg.

Women’s Satisfaction with Comprehensive Abortion Care and Associated Factors in Public Health Facilities of Mojo Town, East Ethiopia
Authors: Oda Tola , Sento Midekso , Negera Atoma
Published: May 2023

Background:

Client satisfaction is an important and commonly used indicator for measuring the quality of health care as it affects clinical outcomes, patient retention, and medical malpractice claims. To limit unintended pregnancies and avoid repeated abortions promoting comprehensive abortion care services is crucial. In Ethiopia problems related to abortion were neglected and access to quality abortion care was very limited. Similarly, information related to comprehensive abortion service, particularly clients’ satisfaction, and associated factors are limited in the study area that the study will be going to fill.

Methods:

A facility-based cross-sectional study design was employed on 255 women who come for abortion service in public health facilities of Mojo town were included consecutively. The data was coded and entered into Epi info version 7 software and exported to SPSS version 20 for analysis. Bivariable and multivariable logistic regression models were applied to identify the associated factors. Model fitness and multicollinearity were checked by using the Hosmer-Lemeshow goodness of fit test and the Variance Inflation Factor (VIF). Adjusted Odds Ratios and their 95% Confidence were reported.

Results:

A total of 255 study subjects were included in this study with a 100% response rate. The study depicted that 56.5% (95% CI: 51.3, 61.7) of the clients were satisfied with comprehensive abortion care. Having college and above educational level (AOR: 0.27; 95% CI: (0.14, 0.95)), Employee occupation (AOR: 1.86; 95% CI: (1.41, 2.93)), medical abortion as a type of uterine evacuation (AOR: 3.93; 95% CI: (1.75, 8.83)) and natural method of family planning users (AOR: 0.36; 95% CI: (0.08, 0.60)) were factors associated with women’s satisfaction.

Conclusion:

The overall satisfaction toward comprehensive abortion care was considerably lower. Waiting time, cleanness of rooms, lack of laboratory service, and availability of service providers are mentioned factors for client dissatisfaction.
The informal rules of candidate selection and their impact on intra-party competition
Authors: Reiser Marion
Published: May 2023

While the literature highlights the relevance of informal rules for candidate selection, empirical research has mainly focused on formal rules and procedures. This article contributes to our understanding by investigating how the informal rules employed by political parties impact on intra-party competition. Using the example of district nominations in Germany, and based on a longitudinal mixed methods design, the inductive analysis reveals five central informal rules: the Incumbency Rule, the Information Rule, the House Power Rule, Fairness Rules and Power-sharing Rules. These rules shape the expectations and behavior of those involved in candidate selection and have a significant impact on various aspects of intra-party competition. They decrease the number of aspirants, reduce intra-party conflict and emphasize the role of local party leaders in organizing and controlling intra-party competition.
A balancing act: Negotiating authenticity in luxury lodges

This study explores the negotiation process underpinning the creation of authentic experiences in luxury lodges. The findings of this study highlight how this is a balancing act performed by the hosts through the provision of an authentic experiential platform connecting guests with unique places and genuine people and is of a luxurious nature. Staged experiences are authenticated by the guests through their bodies and minds, activating, in turn, experiences of existential authenticity. Contributing to service marketing and management literature, the study departs from purely abstract authenticity conceptualisations by applying an experience design and management lens to understanding authentic experiences. Practically, our findings demonstrate how authenticity is operationalised in luxury lodges and how these experiences are understood and valued by tourism and hospitality consumers and providers, providing crucial implications for luxury accommodation marketers and managers.
Response format changes the reading the mind in the eyes test performance of autistic and non-autistic adults
Authors: Lim Alliyza , Brewer Neil , Aistrope Denise , Young Robyn L
Published: May 2023

The Reading the Mind in the Eyes Test (RMET) is a purported theory of mind measure and one that reliably differentiates autistic and non-autistic individuals. However, concerns have been raised about the validity of the measure, with some researchers suggesting that the multiple-choice format of the RMET makes it susceptible to the undue influence of compensatory strategies and verbal ability. We compared the performance of autistic ( N = 70) and non-autistic ( N = 71) adults on the 10-item multiple-choice RMET to that of a free-report version of the RMET. Both the autistic and non-autistic groups performed much better on the multiple-choice than the free-report RMET, suggesting that the multiple-choice format enables the use of additional strategies. Although verbal IQ was correlated with both multiple-choice and free-report RMET performance, controlling for verbal IQ did not undermine the ability of either version to discriminate autistic and non-autistic participants. Both RMET formats also demonstrated convergent validity with a well-validated adult measure of theory of mind. The multiple-choice RMET is, however, much simpler to administer and score.

Lay abstract

Recognizing and understanding the perspectives of others—also called theory of mind—is important for effective communication. Studies have found that some autistic individuals have greater difficulty with theory of mind compared to non-autistic individuals. One purported theory of mind measure is the Reading the Mind in the Eyes Test (RMET). This test presents participants with photographs of pairs of eyes and asks them to identify the emotion displayed by each pair of eyes from four choices. Some researchers have argued that the multiple-choice format of the RMET may not be an accurate measure of theory of mind, as participants could simply be guessing or using a process of elimination to select the correct answer. Participants may also be disadvantaged if they are not familiar with the specific emotion words used in the multiple-choice answers. We examined whether a free-report (open-ended) format RMET would be a more valid measure of theory of mind than the multiple-choice RMET. Autistic and non-autistic adults performed better on the multiple-choice RMET than the free-report RMET. However, both versions successfully differentiated autistic and non-autistic adults, irrespective of their level of verbal ability. Performance on both versions was also correlated with another well-validated adult measure of theory of mind. Thus, the RMET’s multiple-choice format does not, of itself, appear to underpin its ability to differentiate autistic and non-autistic adults.
