Published: May 2020

On 23 July 2014, a commercial aircraft (GE222) crashed near the Ma-Gong Airport on Penghu Island off the southwestern coast of Taiwan as it struggled to land in the stormy weather that was caused by the outer tropical cyclone rainbands (OTCRs) of Typhoon Matmo. This study aims to document the detailed aspects of airflow and precipitation of OTCRs through high-resolution radar and surface observations and to identify how these observed structures contribute to aviation weather hazards. Analyses indicate that the weather at the airport was significantly influenced by the passage of three OTCRs (R1, R2, and R3), and these rainbands share common characteristics of squall-line-like airflow and precipitation structures. As GE222 descended to approach the runway and flew immediately behind and roughly parallel to the leading edge of R3, the aircraft encountered the heaviest precipitation of the rainband and the prominent crosswind that was a manifestation of the rear-to-front flow generated locally by the rainband. The heavy rain–induced poor visibility and the occurrence of strong crosswinds were primary weather hazards affecting this flight event. Momentum budget analyses suggest that the frontward pressure gradient force provided by the near-surface, convectively generated mesohigh played a major role in driving the low-level rear-to-front flow inside the band. The results from the present study imply that closely monitoring convective activities in the outer regions of tropical cyclones and their potential transformation into squall-line-like storms is crucial to complement the routine aviation alert of severe weather under the influence of tropical cyclones.
Fatigue analysis of a composite ring: Experimental and theoretical investigations
Authors: Rafiee Roham , Abbasi Faramarz , Maleki Sattar
Published: May 2020

The behavior of composite rings against fatigue loading is analyzed. Experimental study is performed to evaluate the ultimate hoop strength of the composite ring as a requirement before fatigue testing. Then, fatigue tests are performed at three different load levels. Afterward, progressive damage modeling in the context of continuum damage mechanics is utilized to theoretically estimate fatigue lifetimes of the investigated rings. The modeling consists of three parts as stress analysis, damage estimation and degradation of mechanical properties. It is mainly aimed to reduce the required runtime for the accomplishment of fatigue analysis while the accuracy is at least compromised. Therefore, a manual technique is adapted for extracting stress components on the ring. Degradation of mechanical properties takes place either through gradual procedure or sets of sudden laws. The gradual degradation of mechanical properties is performed based on the damage progression as a function of cycle numbers and stress state. Sudden degradation is done after occurrence of failure. After reduction of mechanical properties, the model is updated and whole procedure repeats till the whole layers fail. Finally, the results of fatigue modeling are compared with performed experimental study and a very good agreement is observed.

Oral mucosal homeostasis is achieved by complex immunologic mechanisms, orchestrating host immunity to adapt to the physiologic functions of the various specialized niches in the oral cavity. Dental implants introduce a novel mucosal niche to the immune system to deal with. Nevertheless, the immune mechanisms engaged toward implants and whether they have broader effects are not well defined. Using a murine model, we found an accumulation of neutrophils and RANKL-expressing T and B lymphocytes in the implant-surrounding mucosa, accompanied by local bone loss. Surprisingly, the presence of implants had an impact on remote periodontal sites, as elevated inflammation and accelerated bone loss were detected in intact distant teeth. This was due to microbial dysbiosis induced by the implants, since antibiotic treatment prevented bone loss around teeth. However, antibiotic treatment failed to prevent the loss of implant-supporting bone, highlighting the distinct mechanisms mediating bone loss at each site. Further analysis revealed that implants induced chronic lymphocyte activation and increased mRNA expression of IFN-α and accumulation of IFN-α–producing plasmacytoid dendritic cells, which we previously reported as bone-destructive immune responses. Collectively, this study demonstrates that implants have a strong and broad impact on oral mucosal homeostasis, inducing periodontal bone loss in a niche-specific manner that is both microbiota dependent and independent.
Memory, writing and narration: The flea markets of memory in Dubravka Ugrešić’s The Museum of Unconditional Surrender
Authors: Marot Kiš Danijela
Published: May 2020

The narrative of Dubravka Ugrešić’s novel The Museum of Unconditional Surrender (1997) revolves around three core motifs: the problem of memory and remembering, the experience of temporality, and the notion of exile, developed in relation to the dichotomy of fact versus fiction. While most theoretical approaches to the novel focus on the motif of exile in the context of dominant ideological patterns of the new national states formed after the breakup of Yugoslavia, this paper represents a shift in interpretative focus to the problem of memory and the experience of temporality in the perspective of the dynamics of history and fiction.
The Psychology of Entrenched Privilege: High Socioeconomic Status Individuals From Affluent Backgrounds Are Uniquely High in Entitlement

Published: May 2020

As rates of intergenerational social mobility decline, it is increasingly important to understand the psychological consequences of entrenched socioeconomic privilege. Here, we explore whether current and childhood socioeconomic status (SES) are interactively related to entitlement, such that among currently high SES individuals, those from affluent backgrounds are likely to feel uniquely high levels of entitlement, whereas currently low SES individuals feel low entitlement regardless of their backgrounds. A meta-analysis of four exploratory studies (total N = 3,105) found that currently high SES individuals who were also raised in high SES households were especially inclined to report feeling entitled, a pattern that was robust across three indicators of SES: income, education, and subjective SES. Results of a preregistered, confirmatory study ( N = 1,058) replicated this interactive pattern for education and subjective SES, though not for income. Our findings highlight the importance of considering current and childhood SES jointly to understand the psychological consequences of SES.
Bioconstitutional Imaginaries and the Comparative Politics of Genetic Self-knowledge
Authors: Hurlbut J. Benjamin , Metzler Ingrid , Marelli Luca , Jasanoff Sheila
Published: May 2020

Genetic testing has become a vehicle through which basic constitutional relationships between citizens and the state are revisited, reaffirmed, or rearticulated. The interplay between the is of genetic knowledge and the ought of government unfolds in the context of diverse imaginaries of the forms of human well-being, freedom, and flourishing that states have a duty to support. This article examines how the United Kingdom, Germany, and the United States governed testing for Alzheimer’s disease, and how they diverged in defining potential harms, benefits, and objects of regulation. Comparison before and after the arrival of direct-to-consumer genetic tests reveals differences in national understandings of what it means to protect life and citizenship: in the United Kingdom, ensuring physical wellness through clinical utility; in the United States, protecting both citizens’ physical well-being and freedom to choose through a framework of consumer protection; and in Germany, emphasizing individual flourishing and an unburdened sense of human development that is expressed in genetic testing law and policy as a commitment to the stewardship of personhood. Operating with their own visions of what it means to protect life and citizenship, these three states arrived at settlements that coproduced substantially different bioconstitutional regimes around Alzheimer’s testing.
A Good Fight: How Indigenous Women Approach Boxing as a Mechanism for Social Change
Authors: Ross MacIntosh , Forsyth Janice
Published: May 2020

This article examines the experiences of select Indigenous female boxers from Canada and the United States to explore and appreciate the diverse meanings they attach to amateur and professional boxing and to write these athletes into history by constructing short case studies of fighters active from the 1970s through the 2010s. We augment each fighter’s story with context from scholarly and secondary source materials, such as newspapers, to round out each woman’s story and to illustrate the multiple overlapping conditions that shaped their boxing experiences. We embrace the work of van Ingen on the importance of understanding female boxers at the intersection of race and gender. In doing so, our work emphasizes the ideological foundations embedded in narratives, so that each narrative presents a certain point of view that results in real practical effects, whether it be supporting White liberal feminism or Indigenous self-determination. Following van Ingen, this article views all writing, whether by journalists or professional historians, as ideological acts, capable of exalting select athletes while marginalizing others.
The effect of age and vision on functional measures of medication management, across different prescription drug container shapes in persons with visual impairment
Authors: Connors Elyse , Curtis Amy , Kim Dae , Freeland Amy
Published: May 2020

The relative effect of age and vision on medication management tasks (time and accuracy of entering the pharmacy phone number and interpreting dose) across four different prescription drug container shapes is examined. A mixed measures three-factor design was employed, with within-subject control. The repeated-measure independent variable of interest was container shape (four conditions), and the two between-subject independent variables were vision and age. Older age and decreased vision were found to be generally negatively associated with time and accuracy of entering the phone number and correct interpretation of dose. Container shape modified the effect of vision and age on the medication management tasks. Interactions between independent variables of age, vision, and container shape make it difficult to recommend one container shape for all participants. The results presented give credence for further examination of packing for label readability and other aspects of medication management, given the ease at which packaging can be modified.
Simulation in perfusion: evaluating the efficacy of a specific training with eye-tracking
Authors: Gierig Sina , Merkle Frank , Pawelke Cynthia , Müller-Plath Gisela
Published: May 2020

Background:

With the aim of integrating simulation training into the training of perfusionists, we examined whether the participants were able to transfer a specific learning content to the same and different situations and assessed their feedback on the simulation training. Eye-tracking was tested as a measure and supplemented by additional measures.

Methods:

A 2 × 2 mixed design was used, with test time (pre- and post-test) and training group (same and different content training) as factors. In the pre- and post-test, the participant had to handle a critical situation on the cardiopulmonary bypass, namely, a drop in arterial partial oxygen pressure. Between the two test times, the participant practised under guidance the handling of either the same critical situation (Group 1) or a different one, that is, impaired venous return (Group 2). Dependent measures were fixations of the eyes on specific areas of interest on the heart-lung machine, measures of latency and subjective assessments. Moreover, participants gave feedback on the simulation training.

Results:

Fixation analyses showed that the training led to an increased gaze on areas of interest relevant to the drop in arterial partial oxygen pressure in both groups, with a significant increase only for Group 1. The surveys revealed a great interest in the integration of simulation training into education.

Conclusion:

In combination with other measures, eye-tracking is suitable for the evaluation of simulation training. Due to the positive training effects and positive participant feedback, the integration of simulation into the training of perfusionists is advocated. Concerning transfer of learning content, more research is needed.

Authors: Harrop Emily , Morgan Fiona , Longo Mirella , Semedo Lenira , Fitzgibbon Jim , Pickett Sara , Scott Hannah , Seddon Kathy , Sivell Stephanie , Nelson Annmarie , Byrne Anthony
Published: May 2020

Background:

Bereavement support is a key component of palliative care, with different types of support recommended according to need. Previous reviews have typically focused on specialised interventions and have not considered more generic forms of support, drawing on different research methodologies.

Aim:

To review the quantitative and qualitative evidence on the effectiveness and impact of interventions and services providing support for adults bereaved through advanced illness.

Design:

A mixed-methods systematic review was conducted, with narrative synthesis of quantitative results and thematic synthesis of qualitative results. The review protocol is published in PROSPERO ( www.crd.york.ac.uk/prospero , CRD42016043530).

Data sources:

The databases MEDLINE, Embase, PsycINFO, CINAHL and Social Policy and Practice were searched from 1990 to March 2019. Studies were included which reported evaluation results of bereavement interventions, following screening by two independent researchers. Study quality was assessed using GATE checklists.

Results:

A total of 31 studies were included, reporting on bereavement support groups, psychological and counselling interventions and a mix of other forms of support. Improvements in study outcomes were commonly reported, but the quality of the quantitative evidence was generally poor or mixed. Three main impacts were identified in the qualitative evidence, which also varied in quality: ‘loss and grief resolution’, ‘sense of mastery and moving ahead’ and ‘social support’.

Conclusion:

Conclusions on effectiveness are limited by small sample sizes and heterogeneity in study populations, models of care and outcomes. The qualitative evidence suggests several cross-cutting benefits and helps explain the impact mechanisms and contextual factors that are integral to the support.
Preventive but nontherapeutic effect of danshensu on hypoxic pulmonary hypertension
Authors: Liu Guang , Zhang Qianqian , Zhang Jinli , Zhang Ning
Published: May 2020

Objectives

Danshensu is a traditional Chinese medicine that is used for treatment of cardiovascular diseases. We previously demonstrated its preventive effect against early-stage hypoxic pulmonary hypertension (HPH) in a rat model. To determine whether danshensu treatment might be useful for patients with chronic HPH, we examined its therapeutic effect in rats with prolonged HPH.

Methods

Adult Sprague-Dawley rats received danshensu (80, 160, and 320 mg/kg) during or after hypoxia exposure to assess preventive and therapeutic effects, respectively. Right ventricle systolic pressure (RVSP), right ventricle hypertrophy index (RVHI), and mean left carotid artery pressure (mCAP) were measured in each group. Western blotting was used to assess transforming growth factor (TGF)-β expression levels in rats and cultured cells exposed to hypoxia.

Results

Preventive danshensu treatment significantly reduced the elevation of RVSP and RVHI in rats exposed to hypoxia, whereas therapeutic danshensu treatment did not; mCAP did not change in any treatment group. The increased expression levels of TGF-β induced by hypoxia were inhibited by preventive danshensu treatment, but not by therapeutic danshensu treatment.

Conclusions

Although danshensu treatment could prevent HPH, it had no obvious therapeutic effect after development of HPH. Therefore, danshensu might be suitable for clinical treatment of early-stage HPH.

Authors: Chen Shukai , Wang Feng , Wei Xiaoyang , Tan Zhijia , Wang Hua
Published: May 2020

The tugboat is the vessel that helps to maneuver large ships for berthing and un-berthing operations. To achieve efficient tugboat operations, investigating the features of tugboat activities is of crucial importance. This study aims to use automatic identification system (AIS) data to identify the maneuver services and analyze the characteristics of tugboat activities. A two-stage algorithm is developed to extract the time, locations, and involved tugboats for berthing and un-berthing operations from AIS data. The AIS data from Tianjin port, China, are used in the case study to demonstrate the effectiveness of the proposed method and analyze the pattern of tugboat activities. First, some important features of tugboat jobs are presented, such as the daily number of jobs and the spatial distribution of jobs. Then, a temporal and spatial analysis is conducted to investigate tugboat assignment, service time, tugboat utilization, and locations of berthing and un-berthing operations. The obtained results and implications could shed light on the deployment of tugboat berths, tugboat scheduling, and evaluation of tugboat fleet operation.
Variability of Reclaimed Asphalt Pavement (RAP) Properties within a State and Its Effects on RAP Specifications
Authors: Austerman Alexander J. , Mogawer Walaa S. , Stuart Kevin D.
Published: May 2020

Reclaimed Asphalt Pavement (RAP) is a highly recyclable material that provides a source of aggregates and asphalt binder to be re-utilized in new paving mixtures. State transportation agencies in the U.S. have constructed their specifications to allow for the use of RAP in new paving mixtures, but with conditions so that suitably performing mixtures are developed. These conditions are imposed because of concerns that the aged binder contained within the RAP may negatively impact the resultant mixtures performances. Many state transportation agencies have constructed their specifications with respect to the AASHTO guidance on utilizing RAP in Superpave mixtures. Questions remain as to the accuracy of these methods, especially if the RAP stockpiles’ properties vary greatly. The purpose of this study was to characterize and compare the properties of the RAP stockpiles being used throughout Massachusetts and to determine the impacts that these properties have on the currently utilized specifications for RAP. The properties of the RAP stockpiles within Massachusetts varied greatly. No geographical or regionalization of RAP properties could be made. By default, the current specifications for using RAP makes no distinction between RAP stockpile properties, especially at smaller percentages like <15% or at low RAP binder ratios (RAPBR). The data from this study demonstrated that this could lead to mixtures without the appropriate virgin binder grade and therefore they could exhibit subpar performance. Specifications should be revised to require more thorough testing of RAP for each mixture design, regardless of the allowable percentage or RAPBR, to ensure adequate mixture performance is maintained.
Building Information Modeling Implementation Framework for Smart Airport Life Cycle Management
Authors: Keskin Basak , Salman Baris
Published: May 2020

Connectivity is key in this new era of smart infrastructure. Smart airports utilize new connected technologies to improve end-user experience while ensuring operational feasibility in aeronautical and non-aeronautical segments. The increasing need for digitizing the design-build-operate life cycles of airports can be met by implementing building information modeling (BIM) that enables accessing, managing, utilizing, and connecting physical and operational data in a digital collaborative environment. This study investigates the current state of practice in airport BIM (ABIM) and the use of ABIM processes in digital airport operations and maintenance by connecting existing data sources and integrating smart airport systems. The study proposes a comprehensive and adaptive ABIM management framework that depicts the alignment and connectivity of ABIM processes, resources and stakeholders with airport operational requirements by identifying gaps in the industry and literature, and developing a global understanding in ABIM visions. Research data are collected through literature and industry review, online surveys, and semi-structured interviews with aviation professionals. Mixed methods including non-parametric statistical analysis and qualitative analysis are used to determine the elements of the framework. Model-based systems engineering (MBSE) principles and language are used to generate the framework. For framework validation, a proof of concept (POC) is conducted by development and deployment of a web-based application. The developed ABIM framework is expected to guide major airport stakeholders in their BIM implementation processes to enhance airport operational efficiencies and in strategizing digital initiatives on a connected-BIM platform.
Developing Technologies and Procedures to Reduce Tracking and Achieve Uniform and Accurate Tack Coat Application
Authors: Coleri Erdem , Villarreal Richard , Wruck Blaine M.
Published: May 2020

The tack coat bond is known to affect the longevity of asphalt pavements. Proper interlayer bonding prevents successive pavement layers from acting independently of one another and creating non-uniform stress and strain profiles in the pavement structure. Poor bonding between pavement layers can result in various pavement failures such as slippage cracking, debonding, and early fatigue cracking, all of which contribute to a reduced pavement fatigue life. Tack coat application rate and uniformity (that can be achieved by uniform tack coat application and by avoiding/minimizing tracking) are two major factors that control the performance of the tack coat bonding and longevity of the pavement structure. In this study, a wireless scale system (OreTackRate) that can be controlled from a tablet computer was developed to measure tack coat application rate accuracy and uniformity. The developed wireless scale system was recommended to be implemented during construction to validate application rate accuracy and uniformity. In addition, a distributor truck certification process was developed and presented in this study. The developed scale system can also be used to determine whether the applied tack coat is cured at any time point during construction. Residual tack coat application rate can also be measured using OreTackRate during construction. Implementation of all these tests, procedures, and technologies is expected to improve the tack coat uniformity during construction and improve the overall longevity of the pavement structure.
Association Between the Postoperative Condition of the Subscapularis Tendon and Clinical Outcomes After Superior Capsular Reconstruction Using Autologous Tensor Fascia Lata in Patients With Pseudoparalytic Shoulder
Authors: Takayama Kazumasa , Yamada Shunsuke , Kobori Yuu , Shiode Hayao
Published: May 2020

Background:

Superior capsular reconstruction (SCR) has been performed for irreparable rotator cuff tear and pseudoparalytic shoulder (PPS); however, poor clinical outcomes have occasionally been reported. Previous studies have shown that the cause of poor clinical results was mainly graft rupture; however, poor clinical outcomes have also been observed in some cases even though the graft was not ruptured.

Hypothesis/Purpose:

We hypothesized that the subscapularis (SSC) tendon would be an important factor affecting clinical outcomes after SCR. The purpose was to clarify the correlation between the condition of the SSC tendon and clinical outcomes after SCR in patients with PPS.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

This retrospective cohort study included 27 patients who had undergone SCR for PPS performed by 1 surgeon between June 2014 and July 2017. The 27 patients were divided into 3 groups for evaluation: group A (n = 12), irreparable supraspinatus (SSP) and infraspinatus (ISP) tears but intact SSC tendon; group B (n = 11), irreparable SSP and ISP tears and repairable SSC tear; and group C (n = 4), irreparable SSP, ISP, and SSC tears. We evaluated the preoperative and postoperative ranges of motion (ROMs; active flexion, abduction, external rotation, and internal rotation), the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form score, and graft condition on magnetic resonance imaging at 12 months postoperatively. All data were analyzed using the Mann-Whitney U, Wilcoxon signed-rank test, and Fisher exact tests, and P < .05 was considered significant.

Results:

Postoperative flexion, abduction, and internal rotation ROMs were significantly lower in group C than in groups A and B (flexion: 70.0° ± 17.8° vs 153.3° ± 14.3° and 154.5° ± 14.3°, P = .003 and P = .003, respectively; abduction: 67.5° ± 15° vs 148.3° ± 22.5° and 140° ± 29.3°, P = .003 and P = .004, respectively; internal rotation: L4 vs Th10 and Th11, P = .005 and P = .008, respectively). All 23 patients in groups A and B were able to recover from PPS; however, no patient recovered from PPS in group C.

Conclusion:

The present study suggests that the SSC tendon is the important factor for achieving good clinical outcomes after SCR in patients with PPS. When the SSC tendon was irreparable, SCR was not an effective treatment for patients with PPS.
Longitudinal Investigation of Posttraumatic Growth in Female Survivors of Intimate Partner Violence: The Role of Event Centrality and Identity Exploration
Authors: Bakaitytė Aistė , Kaniušonytė Goda , Truskauskaitė-Kunevičienė Inga , Žukauskienė Rita
Published: May 2020

The purpose of this study was to investigate the change in posttraumatic growth (PTG) of women survivors of intimate partner violence (IPV) in Lithuania, in relation to the centrality of traumatic experience, identity exploration, and time after exposure to violence. The longitudinal study sample consisted of 217 women who experienced IPV, recruited from women shelters, social support centers, and through counseling psychologists. In this sample the assessment instruments were administered three times during an 18-month period (at 6-month intervals). The results of the study revealed that PTG significantly increased over time for the women who experienced IPV more recently. Those women who experienced IPV more anciently reported higher PTG levels at the beginning of the study, but significant changes in PTG did not emerge. In addition, higher levels of PTG at the beginning of the study were positively associated with event centrality and identity exploration, meaning that those women who perceived their IPV experience as central to their identity and who explored possible identity choices were more likely to have higher levels of PTG at the beginning of the study. However, neither the centrality of the event nor the identity exploration was important for the change in PTG over the study period. Findings of this study highlighted the importance of the first 2-year period after the violence when the potential for PTG and its increase occurs. Limitations of the study and implications for future research are discussed.
Muslim Women’s Purchasing Behaviors Toward Modest Activewear in the United States
Authors: Hwang Chanmi , Kim Tae Ho
Published: May 2020

This study examines Muslim women’s purchasing behaviors toward modest activewear in the United States and tests the underlying mechanism of intent to purchase activewear, based on the theory of planned behavior (TPB). A sample of veiled Muslim women ( N = 328) participated in this study. Results from structural equation modeling revealed that perceived aesthetic attributes and compatibility with regard to apparel functionality, expressiveness, and aesthetics are significant predictors of attitude toward purchasing activewear. Attitude and subjective norm are significantly related to intent to purchase modest activewear, and religiosity indirectly influences purchase intention through the social norm. This research extends the TPB and contributes to the growing body of research on Muslim consumers’ purchasing behavior and to the growing modest apparel market and pro-hijab movement in the industry.
The Association Between Childhood Adversity and Self-Rated Physical Health in US College Students
Authors: Krinner Lisa M. , Warren-Findlow Jan , Bowling Jessamyn
Published: May 2020

Purpose:

Adverse childhood experiences (ACEs) are related to unhealthy behaviors and poor self-rated health. Poor self-rated physical health (SRPH) is negatively associated with college students’ grades and overall academic achievement. This study examined the effects of ACEs on SRPH among undergraduate and graduate students (n = 568; 18-30 years) from a public university in the southeast.

Methods:

Students completed a cross-sectional online survey in October 2018. We conducted unadjusted and adjusted logistic regressions to examine the relationship between ACEs and SRPH among US college students.

Results:

Most participants reported 1 to 4 ACEs; one-fourth reported poor SRPH. Higher ACE exposure increased the odds for poor SRPH in a curvilinear relationship. Unadjusted results indicate ACE exposure increased risk between 82% and 228%, and that higher levels of resilience and adherence to diet and physical activity guidelines reduced risk for poor SRPH. In adjusted models, moderate ACE exposure was associated with 2.46 times greater odds (95% CI = 1.28-9.34) of reporting poor SRPH. Graduate students (odds ratio [OR] = .52, 95% CI = .27-.99) and those who met healthy diet (OR = .12, 95% CI = .02-.93) and physical activity recommendations (OR = .36, 95% CI = .23-.58) had reduced odds of poor SRPH.

Conclusions:

Students who have experienced ACEs are at a greater risk for poor health. Student health programs on campus should take a holistic approach by screening students for childhood adversity and promoting healthy behaviors to improve physical health.
The effect of planetary gear/star gear on the transmission efficiency of closed differential double helical gear train
Authors: Wang Cheng
Published: May 2020

The research of transmission efficiency is of great significance for reducing energy consumption and improving the performance of the device. Researchers have done a lot of work on the calculation of transmission efficiency. However, in the present research work, the quantity of planetary gear/star gear is usually not considered and only a planetary gear/star gear is adopted in the gear transmission efficiency. In practice, in order to increase the stiffness and load capacity of gear train, a plurality of planetary gear/star gears is adopted. The closed differential double helical gear train has been widely used in many fields, such as the main reducer of aircraft engine, lifting mechanism, and the power transmission system of marine ships. Therefore, in this paper, the closed differential double helical gear train is taken as the research object and the effect of planetary gear/star gear on the transmission efficiency is analyzed. Firstly, according to the structure of closed differential double helical gear train, related kinematic analysis is given. Secondly, a graph representation is used to characterize the closed differential double helical gear train. According to the theory of virtual power, the power flow direction of closed differential double helical gear train is determined and the value of split power is obtained. According to the input and output values described in graph representation of closed differential double helical gear train, the formula of transmission efficiency is derived and the effects of planetary gear/star gear on transmission efficiency are analyzed. Finally, an illustrative example shows that compared with the theoretical value, the difference considering the effect of planetary gear/star gear on the transmission efficiency of closed differential double helical gear train is two percentage points.

Published: May 2020

Objectives

The aims of this study were to clarify the activation of complement pathways in patients with lupus nephritis (LN), and to elucidate the association between these complement activation types and clinical outcomes.

Methods

We enrolled 115 patients with biopsy-proven LN from 2003 to 2016 from the lupus cohort at the Busan Paik Hospital and the Jeju National University Hospital in Korea. The patients were divided into two groups based on the patterns of glomerular complements deposits. The presence of C1q, C4 and/or C3 deposits in the glomerulus was considered evidence for the activation of the classical pathway with or without alternative pathway activation (group 1, N = 93), and glomerular C3 deposition without C1q and C4 deposits was considered as a marker for the alternative pathway limited activation (group 2, N = 22). The study end point was progression of kidney disease defined as a ≥50% reduction in estimated glomerular filtration rate from baseline values or advancement to end-stage renal disease.

Results

The mean estimated glomerular filtration rate and median urine protein-to-creatinine ratio of the patients were 85.7 ± 32.4 mL/min/1.73 m2 and 3.1 g/g, respectively, at the time of kidney biopsy. Forty-nine patients (43%) had nephrotic range of proteinuria. Compared to group 1 patients, those in group 2 were older, were more likely to be males and were more hypertensive. In addition, plasma C3 and C4 levels were significantly lower in group 1 patients compared to those in group 2. Moreover, anti-dsDNA concentration was significantly higher in group 1 patients compared to those in group 2. The mean follow-up time was 5.4 ± 3.4 years. The rates of response to one-year immunosuppressive treatment were poorer in group 2 patients compared to those in group 1. During the follow-up time, the progression of kidney disease was significantly higher in group 2 than in group 1 patients.

Conclusion

This study showed that there was alternative complement pathway limited activation in the renal tissue in a small number of patients with LN, and these patients had worse renal outcomes compared to patients with glomerular classical complement pathway activation with or without alternative pathway activation.
Brexit, the Press and the Territorial Constitution
Authors: Davies Gregory , Wincott Daniel
Published: May 2020

Brexit has unveiled previously hidden aspects of United Kingdom (UK) society, law and politics. It provides a valuable opportunity to investigate the social reception of law, and in particular the mediation of the law and constitution in the press. The distinctive constitutional arrangements and histories of Wales, Scotland, Northern Ireland and England have given rise to different territorial interpretations of the UK state. These asymmetries have parallels in the UK’s territorial media landscape, yet we have little understanding of how this landscape contributes to constitutional discourses. This article offers quantitative content and thematic analysis of UK-wide media coverage of major court judgments which have served as critical junctures in the Brexit process. The analysis reveals striking territorial variation in the volume and substance of coverage. Here, the media appears to reinforce divergent understandings of the constitution: while English reporting chimed with a more unitary account of the constitution, reporting elsewhere was more consistent with a vision of the UK as union-state. In the light of these findings, we argue that media analysis can make a valuable contribution to our understanding of the law and the constitution.
How Poor Are People With Disabilities? Evidence Based on the Global Multidimensional Poverty Index
Authors: Pinilla-Roncancio Monica , Alkire Sabina
Published: May 2020

People with disabilities and their families have been recognized as a high-risk population for poverty. Although the number of studies analyzing the levels of poverty of this group has increased, there is still a lack of empirical evidence that establishes whether and how people with disabilities are significantly poorer than families with no disabled members. This study analyses the levels of multidimensional poverty of people living in households with members with disabilities in 11 low- and middle-income countries in different regions of the world, using the global Multidimensional Poverty Index (MPI). The results reveal that in five of the 11 countries people living in households with disabled members face higher levels of multidimensional poverty compared with people without disabilities. In addition, we found that differences between the levels of poverty were larger in middle-income countries than in low-income countries, revealing the existence of a development disability gap.

Published: May 2020

This is an ethnographic study of decision-making concerning tube feeding in the acute phase after a severe stroke. It is based on 6 months of ethnographic research in three stroke units in the Netherlands, where the decision-making on life-sustaining treatment was studied in 16 cases of severe stroke patients. Data were collected through participant observation and interviews. For this article, the analysis was narrowed down to the decision whether or not the patient should receive tube feeding. The data on tube feeding were assembled and coded according to different modes of dealing with this decision in clinical practice, which we refer to as “repertoires.” We discerned three different repertoires: choice, necessity, and comfort. Each repertoire structures clinical practice differently: It implies distinctive ethical imperatives, central concerns, sources of information, and temporalities. We hope our findings can improve decision-making by uncovering its underlying logics in clinical practice.
Clearance Confusion: An Exploratory Analysis of Inpatient Dosing Discordances Between Renal Estimating Equations

Published: May 2020

Background:

Numerous equations exist for estimating renal clearance for drug dosing, and discordance rates may be as high as 40% in certain populations. However, the populations and types of equations used in these studies may not be generalizable to broader pharmacy practice.

Objectives:

To determine the dosing discordance rate between Cockcroft-Gault (C-G), Chronic Kidney Disease Epidemiology (CKD-EPI), and Modification of Diet in Renal Disease (MDRD) equations in a community hospital population.

Methods:

This was a cross-sectional analysis of inpatients who had documented renal function assessment over a 6-month period. Renal estimation was calculated using 5 equations (MDRD, CKD-EPI, and 3 C-G variants). Differences between equations were assessed using mean bias, dosing discordance, and agreement (κ statistic). Patients with acute kidney injury and those requiring renal replacement therapy were excluded.

Results:

A total of 466 patients were eligible for inclusion. Dosing discordance was evident between C-G variants and both MDRD and CKD-EPI equations in greater than 20% of patients. Agreement was highest between MDRD and CKD-EPI (κ = 0.93) and lowest between MDRD and C-G calculated using ideal body weight (κ = 0.33). The majority of discordant instances led to higher dosing recommendations when using MDRD and CKD-EPI equations compared with C-G variants. Dosing discordance exceeded 18% between the different C-G variants, with the highest discordance (36%) observed between total body weight and ideal body weight variants.

Conclusion and Relevance:

Dosing discordance between renal estimating equations is widespread. Practitioners and institutions should be aware of these differences when dosing medications and implementing renal dosing policies.
Leveraging Mobile Sensing and Machine Learning for Personalized Mental Health Care

Mental illness is widespread in our society, yet remains difficult to treat due to challenges such as stigma and overburdened health care systems. New paradigms are needed for treating mental illness outside the practitioner’s office. We propose a framework to guide the design of mobile sensing systems for personalized mental health interventions. This framework guides researchers in constructing interventions from the ground up through four phases: sensor data collection, digital biomarker extraction, health state detection, and intervention deployment. We highlight how this framework advances research in personalized mHealth and address remaining challenges, such as ground truth fidelity and missing data.
Retrospective assessment of the clinical relevance of surgical biopsies of abdominal lymph nodes in cats: 51 cases (2014–2018)
Authors: Corrêa Luís M , Demetriou Jackie L
Published: May 2020

Objectives

The aims of this study were to assess surgical biopsy of abdominal lymph nodes (LNs) in cats taken at the time of exploratory laparotomy and to evaluate any additional benefit of histopathology compared with LN cytology.

Methods

We carried out a retrospective study from a single institution of cats that had abdominal ultrasound and LN biopsies as part of an exploratory laparotomy (2014–2018). Clinical records were reviewed for presenting signs, medical investigations, ultrasound, cytology, surgical findings and histopathology.

Results

Fifty-one cats were included. In total, 60 LNs were biopsied. Forty-four cats had evident LN enlargement at the time of surgery. Nine of those cases were reported to have normal-sized LNs on ultrasound, including one cat that was subsequently diagnosed with lymphoma. Ultrasound-guided LN aspiration was performed in 19 cases. Five of these cats had a histological diagnosis of neoplasia following biopsy, but only one was correctly identified with cytology. Histopathology results were reactive hyperplasia (n = 41), tumour metastasis (n = 11), lymphadenitis (n = 6), inconclusive (n = 1) and normal (n = 1). The most common final diagnoses were inflammatory bowel disease (n = 17/51) and gastrointestinal lymphoma (n = 10/51). There were 15 cats with neoplastic disease; LN biopsies confirmed metastatic disease in 10 and ruled out nodal involvement in five.

Conclusions and relevance

Surgical biopsy of grossly enlarged or normal abdominal LNs provides additional information to LN cytology in cats and in the majority of cases is associated with a positive histological diagnosis. There appears to be the potential to underdiagnose neoplasia with cytology alone.
Experiments and nonlinear analysis of the impact behaviour of sandwich panels constructed with flax fibre-reinforced polymer faces and foam cores

As the effects of climate change become more apparent, it is necessary that environmental impact is considered in every aspect of our society, including the design of new infrastructure. The use of natural materials for building construction is one way to improve the sustainability of infrastructure and therefore it is important that the behaviour of structures made with natural materials be investigated extensively and well understood. In this study, the performance of sandwich panels constructed with flax fibre-reinforced polymer faces and foam cores under impact loading is studied experimentally and analytically. The parameters of the tests were facing thickness (1, 2 and 3 layers of flax fabric) and core density (32, 64 and 96 kg/m3). Each specimen was 1220 mm long, 152 mm wide and approximately 80 mm thick and was tested by a 10.41 kg drop weight impact at mid-span. Each specimen was tested multiple times starting at a drop height of 100 mm and increasing the height by 100 mm for each subsequent test until ultimate failure. The results indicate that the ultimate impact energy increases with both core density and face thickness. The four main failure modes observed were: compression face crushing, compression face wrinkling, core shear and tension face rupture. The failure modes observed generally matched those observed during similar quasi-static testing. Additionally, a nonlinear incremental iterative model was developed based on the conservation of energy during an impact event and the nonlinear mechanical behaviour of both the fibre-reinforced polymer faces and foam cores. This novel model accurately predicts the total deflection and face strains based on the energy of an impact.
Are mass tourists sensitive to sustainability?
Authors: Bernini Cristina , Emili Silvia , Vici Laura
Published: May 2020

Transition management to tourism sustainability is fundamental for mature and mass tourism destinations. While the literature has largely focused on residents’ evaluations of tourism sustainability, little attention has been devoted to investigate tourists’ perceptions and relevance of environmental practices at the destination. This study fills this gap by analyzing tourists’ evaluations of environmental sustainability experienced during their holiday at a mass and mature tourism destination, by focusing on both tourism-based and complementary products. Mapping and cluster analysis are carried out on a sample of tourists who have chosen an Italian mass and mature tourism destination for their holidays. Findings show that sustainability is a less relevant factor and provides less satisfaction with respect to other aspects. Tourist expectations on environmental sustainability are not met; different perceptions and priorities on environmental sustainability are detected in the different tourist clusters. Managerial and policy strategies can be derived from these results.
