Published: October 2019

This study aimed to evaluate the safety and accuracy of mixed reality–based intraoperative three-dimensional navigated pedicle screws in three-dimensional printed model of fractured upper cervical spine. A total of 27 cervical model from patients of upper cervical spine fractures formed the study group. All the C1 and C2 pedicle screws were inserted under mixed reality–based intraoperative three-dimensional image-guided navigation system. The accuracy and safety of the pedicle screw placement were evaluated on the basis of postoperative computerized tomography scans. A total of 108 pedicle screws were properly inserted into the cervical three-dimensional models under mixed reality–based navigation, including 54 C1 pedicle screws and 54 C2 pedicle screws. Analysis of the dimensional parameters of each pedicle at C1/C2 level showed no statistically significant differences in the ideal and the actual entry points, inclined angles, and tailed angles. No screw was misplaced outside the pedicle of the three-dimensional printed model, and no ionizing X-ray radiation was used during screw placement under navigation. It is easy and safe to place C1/C2 pedicle screws under MR surgical navigation. Mixed reality–based navigation is feasible within upper cervical spinal fractures with improved safety and accuracy of C1/C2 pedicle screw insertion.
Diversities of choice, choice of diversities: Practical aspects of a diversity-centered exhibit
Authors: Brett Jeremy
Published: October 2019

A cultural institution choosing to mount an exhibit centered on the theme of diversity (or at least to ensure that a reasonable variety of types of objects/creators is presented) faces an inherent contradiction. Namely, while the human experience is infinite, exhibit space is not. Trying to contain the naturally uncontainable obliges an exhibit curator to make choices of materials, manners of display, and item descriptions, which provide a sense of the subject, knowing that inevitably some people and groups will be excluded. Such was our experience at Cushing Memorial Library & Archives with the creation of our 2019 exhibit The Stars Are Ours: Infinite Diversities in Science Fiction and Fantasy. The exhibit is based around the social, ethnic, racial, gender and other diversities of science fiction and fantasy (SF&F) – diversities in creators, in themes, in characters and in plots. Curatorial decisions respected the overarching exhibit theme while also recognizing the physical reality of the space and ensuring an optimal educational experience for patrons. The exhibit is organized thematically rather than by a specific ‘type’ of diversity, because the idea of boxing groups into specifically delineated, ghettoized areas of the exhibit was counterintuitive to the idea of diversity. Most of the exhibit themes were chosen for their broad nature, which allow for a wider range of authors and works to represent them. Items were chosen that we felt could best reflect the diverse nature of the SF&F genres and demonstrate their commonality as documents of the human cultural experience. Exhibit display is also a process involving many factors. In creating exhibit descriptive material, we sought to make subtle rather than overt connections to the overall exhibit theme where possible. The exhibit, in short, is intended as a diversity ‘sampler’ rather than any sort of attempt to try to capture the breadth of the subject. No exhibit with ‘diversity’ as a theme – whether overtly stated or implied – can realistically do more than acknowledge its inability to be a full chronicle. In doing so, exhibit curators actually recognize, in fact, the deep and limitless richness of their chosen subjects.
Foreign Military Intervention and the Duration of Civil Wars Revisited
Authors: Lawson Fred H.
Published: October 2019

Studies of the impact of foreign military intervention on the duration of civil wars most often fail to distinguish conflicts in which a single external state intervenes from those in which several outside states intervene. One influential quantitative analysis that does explore this distinction (Cunningham, Journal of Peace Research 47(2), 115–127, 2010) focuses primarily on whether or not the interests and preferences of the intervening state(s) coincide with those of prominent local actors. By revising this study’s dataset to clarify the distinction between single-state interventions and multiple-state interventions, it can be demonstrated that the latter are associated with lengthier wars than the former. Both types of foreign military interventions are correlated with civil wars that last longer than average.
Modeling the behavior of bilayer shape memory alloy/functionally graded material beams considering asymmetric shape memory alloy response
Authors: Viet Nguyen Van , Zaki Wael , Umer Rehan , Wang Quan
Published: October 2019

A new model is proposed to describe the response of laminated composite beams consisting of one shape memory alloy layer and one functionally graded material layer. The model accounts for asymmetry in tension and compression of the shape memory alloy behavior and successfully describes the dependence of the position of the neutral surface on phase transformation within the shape memory alloy and on the load direction. Moreover, the model is capable of describing the response of the composite beam to both loading and unloading cases. In particular, the derivation of the equations governing the behavior of the beam during unloading is presented for the first time. The effect of the functionally graded material gradient index and of temperature on the neutral axis deviation and on the overall behavior of the beam is also discussed. The results obtained using the model are shown to fit three-dimensional finite element simulations of the same beam.

Authors: Liu Bingfei , Wang Qingfei , Yin Kai , Wang Liwen
Published: October 2019

A theoretical model for the crack monitoring of the shape memory alloy intelligent concrete is presented in this work. The mechanical properties of shape memory alloy materials are first given by the experimental test. The one-dimensional constitutive model of the shape memory alloys is reviewed by degenerating from a three-dimensional model, and the behaviors of the shape memory alloys under different working conditions are then discussed. By combining the electrical resistivity model and the one-dimensional shape memory alloy constitutive model, the crack monitoring model of the shape memory alloy intelligent concrete is given, and the relationships between the crack width of the concrete and the electrical resistance variation of the shape memory alloy materials for different crack monitoring processes of shape memory alloy intelligent concrete are finally presented. The numerical results of the present model are compared with the published experimental data to verify the correctness of the model.
Development of a Social Skills Education Game for Elementary School Students
Authors: Okada Yoshiko , Matsuda Toshiki
Published: October 2019

Background. The latest Japanese National Curriculum emphasized the importance of active learning as well as communication skills in various subject areas. Following this trend, the social skills education (SSE) approach was adopted to promote and improve skills that facilitate interpersonal conflict resolution in elementary school students.

Aim. This study developed a card game to help elementary school teachers perform SSE. The aims were to convince students to contemplate alternative solutions to problems in a way that incorporates suggestions from other students and to motivate children to think about problem solving in a social context.

Methods. Our card game was developed based on Matsuda’s warp and woof model of problem-solving that emphasizes generating ideas concerning trade-off resolution in problem-solving. We then tested the game in a sample of 74 fourth grade (9-10 years old) elementary school students.

Results. The findings suggest that the students understood the importance of considering new alternatives for trade-off resolution by playing our game.

Conclusions. Despite the limitations of our study, such as the small sample size, our findings demonstrated that the game was successful in teaching most students the necessity of reaching a consensus in situations involving conflicting opinions.
The Detrimental Effects of Punishment and Reward on Cooperation in the Industrial Waste Illegal Dumping Game
Authors: Kitakaji Yoko , Ohnuma Susumu
Published: October 2019

Background. Many studies have shown that sanctions promote cooperation in social dilemma situations. However, it has also been suggested that sanctions have a negative effect. The interactions among people and systems need to be considered to examine the consequences of sanctions.

Aim. We examined whether rewards and mutual punishment increased non-cooperation. We regarded illegal industrial waste dumping as a social dilemma in which everyone bears the burden of the cost of illegal dumping, legal treatment is cooperative behavior, and illegal dumping is non-cooperative behavior.

Method. We used the Industrial Waste Illegal Dumping Game. This game simulates the structure of industrial waste treatment (incomplete surveillance, various industries with different roles and payoffs, cost of cooperation, etc.) in addition to the social dilemma structure. Players take on roles in industrial waste treatment, negotiating and dealing with other players, and treating industrial waste. We set three conditions. In the reward condition, players can earn rewards by rapidly treating industrial waste. In the mutual punishment condition, players can mutually monitor and punish each other. In the control condition, neither reward nor punishment exists.

Results. Non-cooperation occurred more frequently in the reward condition than in the control condition. Conversely, there was no difference in non-cooperation between the mutual punishment and control conditions. Players under the reward condition did not gather information proactively, and information on benefits was not shared.

Conclusion. This study showed that sanctions caused non-cooperation. Social dynamics should be considered when evaluating the effectiveness of sanctions. Gaming allows us to examine social consequences, including social dynamics, which leads to discoveries not possible through traditional methods.
Transforming Health Experience and Action through Shifting the Narrative on Obesity in Primary Care Encounters
Authors: Luig Thea , Keenan Louanne , Campbell-Scherer Denise L.
Published: October 2019

We sought to understand the impact of primary care conversations about obesity on people’s everyday life health experience and practices. Using a dialogic narrative perspective, we examined key moments in three very different clinical encounters, the patients’ journals, and follow-up interviews over several weeks. We trace how people living with obesity negotiate narrative alternatives that are offered during clinical dialogue to transform their own narrative and experience of obesity and self. Findings provide pragmatic insights into how providers can play a significant role in shifting narratives about obesity and self and how such co-constructed narratives translate into change and tangible health outcomes in people’s lives.
Arrhythmia Perception and Quality of Life in Bradyarrhythmia Patients Following Permanent Pacemaker Implantation
Authors: Su Shu-Fen , Wu Meng-Shan
Published: October 2019

Although studies have evaluated the quality of life (QoL) of patients undergoing permanent pacemaker (PPM) placement, their results are inconsistent. To assess arrhythmia perceptions and QoL in bradyarrhythmia patients following PPM implantation, 137 patients completed demographic, arrhythmia perception, and QoL questionnaires before and six months after implantation. Before implantation, they reported fatigue (74.1%), dizziness (72.9%), dyspnea (64.7%), chest pain (62.4%), and heart fluttering (54.1%). After implantation, arrhythmia perceptions and QoL showed significant improvement ( p < .05), except vitality ( p > .05). However, patients with arrhythmia for more than three years, three or more PPM implants, two or more comorbidities, or were 41-50 years showed no significant QoL improvement. Doctors and hospital educators, rather than nurses, provided the most PPM information to patients. Since nurses provide primary in-hospital care to PPM patients, they should impart more patient education while considering individual characteristics in caring situations to enhance patients’ QoL.
Fractional-order kinematic analysis of biomechanical inspired manipulators
Authors: Tenreiro Machado José A , Lopes António M
Published: October 2019

Present-day mechanical manipulators reveal limited performances when compared with the human arm. Joint-driven manipulators are sub-optimal due to the high actuator requirements imposed by the transients of the operational space tasks. Muscle-actuated arms are superior because the anatomic structures adapt the task requirements to the driving linear actuators. However, the advantages of muscle actuation are difficult to unravel using the standard integer-order kinematics based on the integer derivatives, namely the positions, velocities and accelerations. This paper investigates the human arm and evaluates the influence of biomechanics upon the driving actuators by means of a new method of kinematic analysis and visualisation. The proposed method uses the tools of fractional calculus for computing the continuous propagation of the signals between positions and accelerations. The behaviour of the variables is compared in the joint and muscle spaces, using both the kinematics in the time domain and the describing function method. In this line of thought, the classical integer-order kinematics, with three discrete levels of visualisation, is generalised to a continuous description represented by the fractional-order kinematics.
Stability analysis of a two-segment constructed nanotube embedded in an elastic matrix
Authors: Tong Guo-jun , Liu Yong-shou , Cheng Qian , Dai Jia-yin
Published: October 2019

In this paper, the dynamic stiffness method is used to study the stability of a two-segment constructed nanotube embedded in an elastic matrix. The influences of the length ratio, elastic modulus ratio, mass ratio, and elastic coefficient on the stability of the nanotube are investigated. It can be concluded that a change in the elastic coefficient, length ratio, and elastic modulus ratio has no effect on the form of instability of the two-segment constructed nanotube, but a change in the mass ratio has a significant influence on the form of instability of the nanotube. The elastic coefficient of the elastic matrix mainly affects the natural frequency and the critical velocity of the nanotube of the first mode. The change in the length ratio and elastic modulus ratio mainly affects the natural frequency and the critical velocity of the second mode. The mass change in the two materials mainly affects the natural frequency of the nanotube and has no effect on the critical velocity.
Writing the Human “I”: Liminal Spaces of Mundane Abjection
Authors: Tesar Marek , Arndt Sonja
Published: October 2019

This article suggests a theoretical lens of “mundane abjection” as a new conceptualization of liminality as a methodologically and humanistically transformative concept. Thinking with Julia Kristeva’s post-structural conception of the subject as “always in-process,” this article traverses the inherent and transformative element of abjection in relation to the perceived ontological challenges of methodological liminalities. It posits liminality as a potentiating conceptual space for new ontologies in relation to the human “I.” Throughout, the performance, that is the occurrence, of mundane abjection is illustrated as a critical, revelatory and necessary process within this ontological transformation of methodology and the human “I.”

Published: October 2019

Objective: We aimed to investigate the association between sleep in early life and ADHD in adolescence. As a secondary analysis, we tested whether the associations may be specific to ADHD. Method: Data from 3,467 participants of the 2004 Pelotas Birth Cohort were used. Information on their sleep duration and problems was collected at 12, 24, and 48 months of age. ADHD diagnosis and hyperactivity/inattention problems were assessed with the Development and Well-Being Assessment (DAWBA) and the Strengths and Difficulties Questionnaire (SDQ) among participants at 11 years of age. Results: Difficulty going to sleep at 24 months, nightmares at 24 months and at 48 months, and restless sleep at 48 months were consistently associated with ADHD as well as with other mental disorders. Conclusion: The results suggest that sleep disturbances may be more important ADHD predictors than sleep duration or sleep duration trajectories. However, it may also be considered early markers of other mental disorders.
Reproducibility of Grading in Chronic Intervillositis of Unknown Etiology
Authors: Ongaro Deidre , Terry Jefferson
Published: October 2019

Chronic intervillositis of unknown etiology (CIUE) is a rare placental inflammatory process associated with pregnancy loss and recurrence. We conducted a quality assurance study to assess the diagnostic accuracy and reproducibility of CIUE grading at our institution. Hematoxylin and eosin-stained slides from 20 CIUE cases (31 slides) were reviewed by 7 perinatal pathologists in 2 sequential rounds. Reviewers were instructed to use the diagnostic criteria they were presently following for CIUE and to grade each slide according to the Rota scheme. In the first round, 20 slides were assessed. The diagnostic accuracy was 94%, the average percent agreement of Rota grade was 79%, and the Fleiss’ kappa value for interobserver variability was 0.54. The results were reviewed by all pathologists with diagnostic and grading criteria agreed upon prior to the second round. In round 2, the remaining 11 slides were assessed. Diagnostic accuracy was 83%, the average percent agreement on Rota grade was 70%, and the Fleiss’ kappa value for interobserver variability was 0.36. Overall, diagnostic accuracy was high and agreement on Rota grade was moderate. Group review did not appear to improve accuracy. Simplifying CIUE grading to a low-grade/high-grade scheme (<50% or ≥50%) might improve grading reproducibility.

Published: October 2019

Introduction:

To evaluate retinal microvasculature modifications by means of optical coherence tomography angiography in human subjects diagnosed with arterial hypertension and to assess potential clinical relevance for early diagnosis.

Methods:

A cross-sectional study of 30 subjects affected by arterial hypertension compared to a matched cohort of healthy patients was conducted. Patients were evaluated by the Outpatient Clinic for Hypertension and the Retina Center, University of Insubria, Varese, Italy. Patients were divided into three groups: Group 1—healthy subjects, Group 2—patients first diagnosed with hypertension, and Group 3—patients with treated hypertension. Optical coherence tomography angiography was performed applying different analysis protocols for macula and optic disk, using an AngioVue OCTA System on an Optovue device. Morphological data were compared to and correlated with clinical vascular parameters, to evaluate preclinical microvascular damage.

Results:

A significant reduction in deep vascular layer density (Group 1: 59.2% ± 1.5% standard deviation; Group 2: 59.2% ± 2.2% standard deviation; Group 3: 57.8% ± 2.6% standard deviation; p < 0.05) as well as an enlargement of the deep foveal avascular zone area (Group 1: 0.34 ± 0.09 mm2; Group 2: 0.36 ± 0.07 mm2; Group 3: 0.39 ± 0.1 mm2; p < 0.05) was measured in patients with first diagnosed hypertension and in treated patients compared to healthy subjects. We also observed a significant decrease in mean foveal choroidal thickness in affected patients compared to controls (Group 1: 319.68 ± 61.72 µm standard deviation; Group 2: 251.04 ± 63.1 µm standard deviation; Group 3: 262.65 ± 51.08 µm standard deviation; p < 0.05). Our preliminary data did not show a significant correlation with microalbuminuria levels.

Discussion:

Retinal vascular density showed pathological modifications between healthy subjects and hypertensive patients. These preliminary findings suggest that optical coherence tomography angiography may identify pathological markers of an early hypertensive damage and help monitor disease progression with potential therapeutic advantages.
Prospective clinical study using radiostereometric analysis (RSA) to evaluate fixation of a modular cemented polished femoral stem
Authors: Richardson C Glen , Laende Elise K , Gross Michael , Dunbar Michael J
Published: October 2019

Background:

The long-term clinical success of cemented polished tapered femoral components has been demonstrated in prospective as well as registry studies. This stem design type has also been well studied with radiostereometric analysis (RSA) and provides a standard to evaluate alternative designs of polished tapered cemented femoral components. This prospective study evaluates the subsidence of a polished cemented stem with a modular neck design utilising RSA.

Methods:

26 patients were prospectively enrolled in the study and 23 were available for RSA analysis at 2 years.

Results:

The average subsidence of the femoral implant was 1.1 mm (SD 0.4 mm) at 2 years post operation. There were no revisions in this group, specifically no failures of the modular stem-neck design as has been seen with other implants.

Conclusions:

The RSA subsidence pattern at 2 years of this cemented femoral stem is similar to other successful designs with long-term follow-up. The implications over time of stem neck modularity for cemented polished tapered femoral components requires further evaluation.

Recent evidence supports the relationship between in-hospital hyperglycemia and inpatient complications. Besides, glycated hemoglobin (HbA1c) can predict the clinical course of patients with type 2 diabetes mellitus (DM2) during hospital stays. This study aimed to assess the relationship between HbA1c levels and inpatient outcomes. Type 2 diabetes mellitus patients with age greater than 18 years, hospital length of stay greater than 24 hours, and one HbA1c report during their in-hospital management were included. All the electronic care records of patients admitted at the Clinical Versalles, a high-volume institution, in Manizales-Colombia were revised. The following variables were considered: hospital length of stay, diagnoses at the arrival, complications, capillary glucose levels, and treatment at discharge. Variables were categorized by HbA1c levels: group 1 = ⩽ 7%, group 2 = 7.01% to 8.5%, group 3 = 8.51% to ⩽10% and group 4 = >10%. There were a total of 232 patients. Average age was 69.7 years, mean HbA1c was 7.19 ± 2.03, average body mass index (BMI) was 28.8 ± 5.6. About HbA1c, 146 (62.9%) had ⩽7.5%. The most frequent admission diagnosis was by cardiovascular diseases. Average hospitalization was 7.5 ± 5.7 days. There was no relationship between the levels of HbA1c with hospital stays, inpatient complications, or readmissions. Infections and respiratory diseases were more common conditions related to higher HbA1c levels, especially when these were 8.5%. In diabetic patients with nonsurgical diseases and high HbA1c levels, there was no association with clinical complications, length of stay, readmissions, or in-hospital mortality, but changes in treatment at discharge were observed.
Early Introduction of Dermatology Clinical Skills in Medical Training
Authors: Blakely Kim , Bahrani Bahar , Doiron Philip , Dahlke Erin
Published: October 2019

Background

Skin diseases are among the most common diseases encountered by healthcare professionals. Despite this, dedicated dermatology teaching is limited in most Canadian medical school training programs. This is especially true of clinical skills training.

Objectives

To determine the impact of early introduction of dermatology clinical skills in Canadian undergraduate medical training. Secondary objectives included examining the impact of having sessions co-led by a clinician with expertise in the field of dermatology.

Methods

A half-day dermatology clinical skills session was introduced in the University of Toronto preclerkship medical school during the dermatology week. Sessions were co-led by staff or resident dermatologists. Sessions were evaluated using student pre- and postclinical skills test scores, as well as experience questionnaires completed by both tutors and students.

Results

The clinical skills session was well received by both students and tutors, with no cumulative score less than 4.34 on a 5-point Likert scale. The majority of students agreed or strongly agreed that the introduction of clinical skills in the early years of the curriculum facilitated learning consolidation (99.5%). Comparison of pre- and post-test scores showed that students’ dermatology comprehension improved by an average of 12.1% following completion of the session. In questionnaire responses, students and nondermatology co-tutors emphasized the impact of having an expert in the field of dermatology co-lead the session.

Conclusions

Students valued early clinical skills exposure to dermatology and felt it enhanced their knowledge and abilities. This study demonstrates learning consolidation when dermatologic didactic teachings are paired with practical clinical skills sessions.

Published: October 2019

Multiple sclerosis (MS)-related tremor is frequent and can often be refractory to medical treatment, which makes it a potential source of major disability. Functional neurosurgery approaches such as thalamic deep brain stimulation (DBS) or radiofrequency thalamotomy are proven to be effective, but the application of invasive techniques in MS tremor has so far been limited. Magnetic resonance (MR)-guided focused ultrasound thalamotomy, which has already been approved for treating essential and parkinsonian tremor, provides a minimally invasive approach that could be useful in the management of MS tremor. We report for the first time a patient with medically refractory MS-associated tremor successfully treated by focused ultrasound thalamotomy.
Fitness testing experiences in integrated physical education as reflected by adults with visual impairments
Authors: Haegele Justin A , Zhu Xihe , Holland Katherine
Published: October 2019

The purpose of this study was to describe the experiences of adults with visual impairments regarding fitness testing during their integrated physical education experiences. An interpretative phenomenological analysis research approach was used and 11 adults (ages 20–35 years) with visual impairments acted as participants. The primary sources of data were semi-structured audiotaped telephone interviews and reflective interview notes. Thematic development was undertaken using a three-step analytical process. Based on the data analysis, the following three interrelated themes were constructed from the data: (a) ‘decent at sit-ups, but the others were embarrassing’: mixed feelings about performance; (b) ‘I couldn’t reach my full potential’: forced exclusion/inclusion; and (c) ‘I felt like a museum exhibit’: navigating unwanted social attention. These themes extend the current literature by describing salient features of fitness testing that influence the meaning that individuals with visual impairments place on those experiences.
Brand prestige and affordable luxury: The role of hotel guest experiences
Authors: Lo Ada , Yeung Michelle Au
Published: October 2019

The concept of affordable luxury has elicited attention among hoteliers in recent years. This study developed and tested an instrument to measure hotel guest experiences of an affordable luxury hotel and investigated the influence of three dimensions of hotel guest experience on brand prestige (BP) namely physical environment (PE), guest-to-staff encounters (GSEs), and guest-to-guest encounters (GGEs). A total of 423 usable self-administered questionnaires were obtained from the guests of an affordable luxury hotel. Exploratory factor analysis and confirmatory factor analysis were used to reduce and confirm the measurement model of the proposed constructs, respectively. Structural equation modeling was adopted to test the proposed relationships. All three dimensions are significant antecedents of BP. PE is the most important, followed by GSEs, and then GGEs. A modified importance–performance analysis (IPA) was conducted by comparing the perceived performance and the derived importance of the guest experience attributes. This demonstrates how individual hotel can use the IPA to identify specific areas of improvement on the hotel guest experience attributes.
Localization, diversification and heterogeneity: Understanding the linguistic and cultural logics of Indian new media
Authors: Mehta Smith
Published: October 2019

In this article, I foreground the granular movements that determine the ubiquitous nature of India’s new media economy created by the advent of streaming media platforms and the emergence of regional online content creators in India. I argue that the increasing preference of Indian audiences to consume online content in their own language has led to a demand for ‘regional’ content, whereby streaming platforms and online creators are increasingly investing in ‘non-Hindi’ and ‘non-English’ language content to cater to the linguistically and culturally diverse Indian population. Through a primary focus on online content creation practices in Bengali and Marathi languages, the article explores their ‘local’, ‘regional’, ‘transnational’ and ‘global’ appeal, and subsequent blurring of boundaries between ‘regionalization’ and ‘localization’. The remainder of the article focuses on the emerging diaspora of regional online content creators who are adopting distinct content strategies to develop relationships with online communities based on commonalities of language and culture.
Seismic performance and improvements of split-foundation buildings in across-slope direction
Authors: Xu Gang , Zhang Ruijun , Li Aiqun
Published: October 2019

The seismic performance and damage pattern of the split-foundation frame buildings in across-slope direction are studied. In view of the characteristics of split-foundation structure, the parameter analyses of split-foundation structure with different spans and floors of lower and upper parts are studied, and the main factors affecting the torsional effect of split-foundation structure are also studied theoretically. Finally, the improvements and design procedure of split-foundation structure are put forward to reduce the difference in ductility demands between the upper ground columns and the lower part. Results show that the torsional effect of split-foundation structure is very significant because of the rigidity eccentric. The upper ground columns are the weakest parts of split-foundation structure which are destroyed first under the earthquake action; then, the lower floors are destroyed in succession. Lower ductility demands of the upper ground columns and better seismic performance of the split-foundation structure can be achieved by the designed improvements.
Implementing variable valve actuation on a diesel engine at high-speed idle operation for improved aftertreatment warm-up
Authors: Vos Kalen R , Shaver Gregory M , Joshi Mrunal C , McCarthy James
Published: October 2019

Aftertreatment thermal management is critical for regulating emissions in modern diesel engines. Elevated engine-out temperatures and mass flows are effective at increasing the temperature of an aftertreatment system to enable efficient emission reduction. In this effort, experiments and analysis demonstrated that increasing the idle speed, while maintaining the same idle load, enables improved aftertreatment “warm-up” performance with engine-out NOx and particulate matter levels no higher than a state-of-the-art thermal calibration at conventional idle operation (800 rpm and 1.3 bar brake mean effective pressure). Elevated idle speeds of 1000 and 1200 rpm, compared to conventional idle at 800 rpm, realized 31%–51% increase in exhaust flow and 25 °C–40 °C increase in engine-out temperature, respectively. This study also demonstrated additional engine-out temperature benefits at all three idle speeds considered (800, 1000, and 1200 rpm, without compromising the exhaust flow rates or emissions, by modulating the exhaust valve opening timing. Early exhaust valve opening realizes up to ~51% increase in exhaust flow and 50 °C increase in engine-out temperature relative to conventional idle operation by forcing the engine to work harder via an early blowdown of the exhaust gas. This early blowdown of exhaust gas also reduces the time available for particulate matter oxidization, effectively limiting the ability to elevate engine-out temperatures for the early exhaust valve opening strategy. Alternatively, late exhaust valve opening realizes up to ~51% increase in exhaust flow and 91 °C increase in engine-out temperature relative to conventional idle operation by forcing the engine to work harder to pump in-cylinder gases across a smaller exhaust valve opening. In short, this study demonstrates how increased idle speeds, and exhaust valve opening modulation, individually or combined, can be used to significantly increase the “warm-up” rate of an aftertreatment system.
Intimate Partner Violence and Work: A Scoping Review of Published Research
Authors: MacGregor Jennifer C. D. , Oliver Casey L. , MacQuarrie Barbara J. , Wathen C. Nadine
Published: October 2019

Increasingly, intimate partner violence (IPV) is recognized as having important impacts on work. The purpose of this scoping review is to describe the nature and extent of research on IPV and workers, the workplace, and/or employment. Using multiple search strategies, including searches conducted by a professional librarian from database inception to May 2018, 2,306 unique articles were retrieved and independently screened for eligibility by two team members. A total of 235 articles met predefined inclusion criteria, which were that articles must: (1) report findings of a research study, (2) be published in a peer-reviewed journal, and (3) be focused on IPV and the workplace, workers, and/or employment. The most common topics examined were the relationship between IPV and employment, IPV- and work-related factors, and the impacts of IPV on work. Most articles were quantitative and cross-sectional and focused on the abuse of women by men. Major research gaps include evaluations of interventions to address IPV and work and research focused on the experiences and needs of perpetrators and gender and sexual minorities. Further evidence synthesis is recommended in several areas and implications for policy and practice are discussed.
Harnessing Knowledge for Improving Access to Fruits and Vegetables at Farmers Markets: Interactive Data Visualization to Inform Food Security Programs and Policy
Authors: Johnson Matilda O. , Cozart Thometta , Isokpehi Raphael D.
Published: October 2019

High consumption of fruits and vegetables leads to decreased risk of various chronic diseases, including obesity and cardiovascular disease. Community-level barriers to access fruits and vegetables include the high cost, limited availability, and transportation. Farmers markets are a priority strategy for improving community access to fresh fruits and vegetables. The U.S. Department of Agriculture (USDA) National Farmers Market Directory is a voluntary self-reported data source on farmers markets. The objective of this investigation of the USDA farmers markets data directory was to determine how farmers markets in the United States are grouped according to (1) availability of fruits and vegetables and (2) the payment accepted. We designed and implemented interactive data visualizations in visual analytics software to understand access to fruits and vegetables at farmers markets from 8,497 entries in the USDA Farmers Market Directory. Among the 665 new or updated entries in year 2018, a subset of 641 (96%) farmers markets with availability of fresh fruits and vegetables had 16 subgroups. Additionally, a subgroup of 102 (16%) farmer markets accepted all four federal nutrition assistance benefits (SFMNP, SNAP, WIC CVVs, and WIC FMNP). The interactive data visualizations including geographic maps connected to social media resources can be useful in advocacy efforts and can inform policy improvements designed to improve physical, social, and economic access to fruits and vegetables at farmers markets.

History has recorded the aggressive fandom campaigns of the 2010s, which drove vulnerable minority actors from their careers and homes. #GamerGate was the most iconic of these movements with its claim to focus on the ethics in games journalism. This article examines select news coverage of the #GamerGate movement from its initial outset in 2014 to today to identify how the movement changed news reporting’s approach to fandom harassment stories. #GamerGate’s development and deployment media of frames were examined to see how the repertoires of contention shaped during this period played into social and political events that followed.
A Study of Clinical Applications of Perforator-Based Propeller Flaps in Leg Reconstructive Surgery: A Single-Center Experience of 40 Cases

Published: October 2019

Soft tissue management in lower limb poses a considerable challenge to a reconstructive plastic surgeon. Perforator-based propeller flaps can cover large wounds without sacrificing a major vascular axis and allows reconstruction using nearby similar tissues, thereby following the principle of replace like with like. This study was undertaken with the objective to look for the results of propeller flap in lower limb reconstruction and how the results can be improved. This was a retrospective study on 40 patients who underwent the reconstruction of soft tissue defects of lower limb with propeller flap. All the relevant data were collected and analyzed. Patients with soft tissue defect anywhere in the leg were included, but patients who had history of degloving injury, peripheral vascular disease, and diabetes mellitus were excluded. All these patients were divided in 2 groups according to the angle of rotation of propeller flap. Group I had 20 patients in which the flap was rotated by 150° to 180°. Group II had 20 patients, and the flap was rotated by 90° to 150°. Postoperatively, the first 2 cases in Group I showed total flap congestion and had complete necrosis, which were debrided and an alternate method was used to reconstruct. Thereafter, no patient had total flap necrosis. Minor complications were seen in 3 patients who showed transient venous congestion of the flap. Group II had no flap necrosis except for mild dehiscence, which was managed by secondary suturing. In most cases, the aesthetic result was acceptable and patients were completely satisfied. When parameters of the defect are suitable for treatment with a propeller-based local flap, this technique may be considered as the first option for surgical reconstruction. Proper planning, location of perforator with preoperative and intraoperative audio Doppler, and use of magnification would make this procedure more successful and definitely decrease the use of long-duration microvascular surgery.

The Quality Improvement and Research Committee of the Society for Vascular Ultrasound has recognized the Journal for Vascular Ultrasound to promote quality improvement, research and scholarly initiatives of the Society. An understanding of the content and character of its published articles and its status amongst journals on vascular ultrasound will be useful to this mandate. This project aims to identify the scope of Journal for Vascular Ultrasound and its implications for the Society membership. Journal for Vascular Ultrasound Volumes 40 to 42 (2016-2018) were reviewed to identify the number of articles published, the type of scholarly work, and the vascular ultrasound domains represented. The findings were compared with major databases and a targeted list of journals with vascular ultrasound content. In addition, bibliometric parameters specific to Journal for Vascular Ultrasound were identified and compared with other journals. The Journal for Vascular Ultrasound published 71 articles over the 3 years; 100% were vascular ultrasound topics. The most frequent activities were 35 cases, 20 research, and 5 guidelines. The topics were 19 venous, 18 carotid, 7 arterial, 2 aorta, 1 education, and 10 unusual findings, and 4 other studies. In the 312 targeted journals, 4792 articles were published in 2018; 135 were relevant to vascular ultrasound. The maximum vascular ultrasound content in any one journal, other than Journal for Vascular Ultrasound, was 20% (range = 0-20, median = 8%). The impact of Journal for Vascular Ultrasound, by the H-score of 11 and SJR of 0.12, ranks the Journal for Vascular Ultrasound in the lowest 10% of surveyed journals. Of the citable Journal for Vascular Ultrasound articles, only 6% were cited in bibliometric analysis. The Journal for Vascular Ultrasound has the highest percentage of content of vascular ultrasound of targeted journals. Case reports represent the bulk of Journal for Vascular Ultrasound published work. Citations and impact remain low. None of the targeted journals have very much content in vascular ultrasound. These findings suggest a variety of challenges and opportunities for the Society.
Clinicopathological features in membranous nephropathy with cancer: A retrospective single-center study and literature review

Background:

Membranous nephropathy is the most common glomerular disease related to malignancy. However, it is difficult to distinguish between true malignancy-related membranous nephropathy and idiopathic membranous nephropathy coincident with cancer. It has been reported that phospholipase A2 receptor (PLA2R) is the first autoantigen involved in idiopathic membranous nephropathy and thrombospondin type-1 domain-containing 7A (THSD7A) may have a close relationship with malignancy-related membranous nephropathy. Therefore, the aim of this study was to compare the clinicopathological characteristics between membranous nephropathy patients with cancer and idiopathic membranous nephropathy patients without cancer to better detect malignancy-related membranous nephropathy, including glomerular PLA2R and THSD7A depositions and their circulating antibodies, together with glomerular IgG4 deposition.

Methods:

Twelve membranous nephropathy patients with cancer and 257 idiopathic membranous nephropathy patients without cancer were included in this study and had been followed up for more than 1 year. The glomerular expression of PLA2R, THSD7A, and IgG4 was analyzed by immunohistochemistry. Circulating anti-PLA2R and anti-THSD7A antibodies were assessed by enzyme-linked immunosorbent assay and indirect immunofluorescence testing, respectively.

Results:

Membranous nephropathy patients with cancer were significantly older and had higher serum creatinine and a lower estimated glomerular filtration rate than idiopathic membranous nephropathy patients ( P<0.05). The positive rates of glomerular PLA2R and IgG4 depositions and circulating anti-PLA2R antibodies in membranous nephropathy patients with cancer were significantly lower than those in idiopathic membranous nephropathy patients without cancer ( P<0.01).

Conclusion:

The absence of glomerular PLA2R deposition and negative circulating anti-PLA2R antibodies, along with negative glomerular IgG4 staining, may be useful clues to more accurately screen underlying malignancies in membranous nephropathy patients.
Prison autobiographical narratives: Making sense of personal and social (racial) transformation
Authors: Lynn Vanessa
Published: October 2019

This article investigates autobiographical public narratives of people who are, and were, incarcerated during different regimes of injustices in the United States—from the civil rights era to the current era of mass incarceration. People make sense of their experiences with race and racism through time, from a present standpoint of incarceration or freedom, in retrospect via proximate and distant memories of injustices, and toward a vision of the future. I juxtapose mainstream autobiographies from Malcolm X to Shaka Senghor with public blog posts from individuals incarcerated who provide autobiographical accounts to the world. I find that generations of incarcerated people who came of age during the height of the War on Drugs of the 1980s and 1990s project a narrative of a neoliberal subject who has a more individualistic and de-racialized idea of transforming their moral self and community. This contradicts with the way they portray prison as being a conduit for creating communities of racial solidarity and racial consciousness. Highly influenced and inspired by other narratives of radical prisoners of conscience of the 1960s and 1970s who were prone to view their liberation, and of the Black community, through vanquishing White supremacy, the new generation speaks to the color-blind narratives that pervade mainstream society and possible in narrative interventions correctional program.
