Authors: Ferah Bahar , Gemci Ayse Gul , Algburi Omar 
Published: August 2022

PurposeThis paper's main objective emphasizes the importance of waterfront design in coastal cities. It reveals that a location is associated with the activities it hosts to become attractive for people or, in other words, to be a destination. In this respect, it proposes students' concept projects for the selected waterfront field study in Istanbul.Design/methodology/approachThis study's conceptual framework is designed according to the qualities compiled from the place-diagram and the power of 10+ (plus) concepts of the PPS (project for public spaces). Accordingly, a fieldwork study based on the qualitative and quantitative research method was conducted as fieldwork in the Istanbul Sarayburnu waterfront, where historical and touristic sight-seeings of the Golden Horn meet with the Bosphorus coastal line. In addition to photo-video recordings, survey questions were also prepared during the field study.FindingsSurvey questions inquiries multi questions searching for the place-diagram qualities provide suggestions of 90 people who responded in situ. Results of the case study highlight six alternative proposal projects for the fieldwork prepared based on the power of 10+ concept by the third grade students of the School of Architecture of Istanbul Sabahattin Zaim University (IZU). Based on the survey questions and literature review findings, 10 sub-spatial qualities of waterfronts were disaggregated at the end of the study.Research limitations/implicationsThe power of 10+ concept in the study provides a gauge for architects and urban planners; it gives them an excellent tool for assessing the quality of public spaces for placemaking in waterfronts.Originality/valuePrevious studies have generally been based on the PPS's place-diagram qualities with little mention of the interaction with the power of 10+ concept in placemaking. The proposed sub-qualities in the paper's conclusion contribute to architects and urban planners considering a model approach derived from those PPS concepts.
Women leaders' work-caused trauma: vulnerability, reflexivity and emotional challenges for the researcher
Authors: Mavin Sharon 
Published: August 2022

PurposeThis paper advances what is known about emotional experiences and challenges when researching work-caused trauma in organisations and illustrates learning for researchers of work-related trauma. Viewing vulnerability as strength could be conceived as an oxymoron. The paper explains how vulnerability can lead to strength for researchers/participants and focuses on researcher reflexivity in relation to one interview with a woman leader in a small-scale qualitative study.Design/methodology/approachThe research protocols of the qualitative study are outlined: pre-interview briefings, participant journaling and semi-structured interviews. Researcher reflexivity, following Hibbert's (2021) four levels of reflexive practice (embodied, emotional, rational and relational), is applied to an interview with a woman leader.FindingsThe paper illustrates how research design and recognising vulnerability as strength facilitates considerable relational work and emotional experiences. Researcher reflexivity conveys impact of work-caused trauma on participants and researchers. The paper advances understandings of vulnerability as strength in practice, emotional experiences and challenges of work-caused trauma research.Research limitations/implicationsIn this paper, a single case of researcher reflexivity is considered.Practical implicationsThere are practical implications for researcher relationships with participants; demonstrating emotional awareness; responding to traumatic stories, participant distress and impact on the researcher; issues of vicarious/secondary traumatic stress; having safe psychological systems; scaffolding a process which recognises vulnerability as strength and becoming personally and methodologically vulnerable; risk of embodied and emotional impact; commitment to reflexivity and levels of reflexive practice.Originality/valueThere is lack of researcher reflexive accounts of practice when studying trauma. Few scholars suggest ways to support researchers in challenging and difficult research. There is silence in research exploring leaders' experiences of work-caused trauma. This paper provides a reflexive account in practice from a unique study of women leaders' experiences of work-caused trauma.
Thermal modeling of directed energy deposition additive manufacturing using graph theory
Authors: Riensche Alex , Severson Jordan , Yavari Reza , Piercy Nicholas L. , Cole Kevin D. , Rao Prahalada 
Published: August 2022

Purpose
The purpose of this paper is to develop, apply and validate a mesh-free graph theory–based approach for rapid thermal modeling of the directed energy deposition (DED) additive manufacturing (AM) process.

Design/methodology/approach
In this study, the authors develop a novel mesh-free graph theory–based approach to predict the thermal history of the DED process. Subsequently, the authors validated the graph theory predicted temperature trends using experimental temperature data for DED of titanium alloy parts (Ti-6Al-4V). Temperature trends were tracked by embedding thermocouples in the substrate. The DED process was simulated using the graph theory approach, and the thermal history predictions were validated based on the data from the thermocouples.

Findings
The temperature trends predicted by the graph theory approach have mean absolute percentage error of approximately 11% and root mean square error of 23°C when compared to the experimental data. Moreover, the graph theory simulation was obtained within 4 min using desktop computing resources, which is less than the build time of 25 min. By comparison, a finite element–based model required 136 min to converge to similar level of error.

Research limitations/implications
This study uses data from fixed thermocouples when printing thin-wall DED parts. In the future, the authors will incorporate infrared thermal camera data from large parts.

Practical implications
The DED process is particularly valuable for near-net shape manufacturing, repair and remanufacturing applications. However, DED parts are often afflicted with flaws, such as cracking and distortion. In DED, flaw formation is largely governed by the intensity and spatial distribution of heat in the part during the process, often referred to as the thermal history. Accordingly, fast and accurate thermal models to predict the thermal history are necessary to understand and preclude flaw formation.

Originality/value
This paper presents a new mesh-free computational thermal modeling approach based on graph theory (network science) and applies it to DED. The approach eschews the tedious and computationally demanding meshing aspect of finite element modeling and allows rapid simulation of the thermal history in additive manufacturing. Although the graph theory has been applied to thermal modeling of laser powder bed fusion (LPBF), there are distinct phenomenological differences between DED and LPBF that necessitate substantial modifications to the graph theory approach.

Authors: Gao Bolin , Zheng Kaiyuan , Zhang Fan , Su Ruiqi , Zhang Junying , Wu Yimin 
Published: August 2022

Purpose
Intelligent and connected vehicle technology is in the ascendant. High-level autonomous driving places more stringent requirements on the accuracy and reliability of environmental perception. Existing research works on multitarget tracking based on multisensor fusion mostly focuses on the vehicle perspective, but limited by the principal defects of the vehicle sensor platform, it is difficult to comprehensively and accurately describe the surrounding environment information.

Design/methodology/approach
In this paper, a multitarget tracking method based on roadside multisensor fusion is proposed, including a multisensor fusion method based on measurement noise adaptive Kalman filtering, a global nearest neighbor data association method based on adaptive tracking gate, and a Track life cycle management method based on M/N logic rules.

Findings
Compared with fixed-size tracking gates, the adaptive tracking gates proposed in this paper can comprehensively improve the data association performance in the multitarget tracking process. Compared with single sensor measurement, the proposed method improves the position estimation accuracy by 13.5% and the velocity estimation accuracy by 22.2%. Compared with the control method, the proposed method improves the position estimation accuracy by 23.8% and the velocity estimation accuracy by 8.9%.

Originality/value
A multisensor fusion method with adaptive Kalman filtering of measurement noise is proposed to realize the adaptive adjustment of measurement noise. A global nearest neighbor data association method based on adaptive tracking gate is proposed to realize the adaptive adjustment of the tracking gate.

AbstractThe real‐world treatment landscape for patients with moderate‐to‐severe psoriasis receiving systemic therapies in Japan is not well understood. This study describes the demographic and clinical characteristics, treatment patterns, healthcare resource utilization, and psoriasis‐associated costs in these patients. This retrospective observational study used data from the Japan Medical Data Center database between January 2016 and December 2020. Eligible patients had a confirmed diagnosis of psoriasis, ≥1 claim for a systemic treatment of interest, medical history for ≥6 months, and follow‐up data for ≥12 months. Systemic therapies comprised biologics (tumor necrosis factor and interleukin inhibitors) and oral treatments (a phosphodiesterase‐4 inhibitor, immunosuppressants, and vitamin A). Patient demographics and clinical characteristics, treatment patterns, healthcare resource utilization, and costs were evaluated. The study identified 1770 patients satisfying all inclusion criteria. The mean age was 49.0 years, with 68% of patients aged 20–54 years. Overall, 90.6% and 9.4% of patients received oral medications and biologics as index treatment, respectively. Treatment patterns, healthcare resource utilization, and costs were assessed for treatments received by ≥20 patients (n = 1730). During the 12‐month follow‐up period, 1102/1730 patients (63.7%) discontinued index treatment, of whom 9.9% switched to alternative systemic treatments. The persistence rate was ≥70% for most biologics and <50% for oral systemic treatments. All 1730 patients had ≥1 all‐cause outpatient visit (2.0 visits per person per month) and hospitalization frequency was ≤0.01 per person per month. Persistent patients incurred inflation‐adjusted costs of Japanese Yen (JPY) 88 667 per person per month. Treatment switching was associated with an increase in total cost: JPY 128 039 per person per month after switching versus JPY 117 504 before switching. This study of Japanese patients with moderate‐to‐severe psoriasis demonstrated low persistence, high discontinuation, and low rates of treatment switching with systemic therapies. Switching was associated with increased total cost. These results indicate unmet needs for new treatments.
Physiological costs of facultative endosymbionts in aphids assessed from energy metabolism

Abstract

Many insect species harbour heritable bacterial endosymbionts. Some facultative endosymbionts provide benefits to their hosts under certain environmental conditions.

Facultative endosymbionts are expected to impose additional energetic expenditures to their host, reducing host fitness. While there is accumulating evidence in plant sucking insects that facultative endosymbionts reduce the fitness of their host under permissive conditions, no direct energy costs associated with facultative endosymbionts have been identified.

Using the standard metabolic rate (SMR) as a measure of the energy cost of self‐maintenance, we investigated whether two common facultative endosymbionts Hamiltonella defensa or Regiella insecticola increase the maintenance cost of the pea aphid Acyrthosiphon pisum which could translate into host fitness reduction (‘compensation hypothesis’). In addition, we tested if there was a link between SMR and the aphid fitness and whether it depended on endosymbiont density and aphid energetic reserves. Finally, we measured SMR at different temperatures to assess the impact of suboptimal thermal conditions on physiological cost of endosymbionts.

In the presence of facultative endosymbionts, aphids expressed generally a lower fitness and a higher SMR compared to uninfected ones, in accordance with the ‘compensation hypothesis’. However, the SMR difference between infected and uninfected aphids tended to decrease with increasing temperature. Complex host genotype‐by‐symbiont genotype‐by‐temperature interactions on SMR were also revealed.

Energetic budget of adult aphids appeared weakly influenced by the aphid genotype and endosymbiont species, suggesting that facultative endosymbionts primarily impact the consumption of energy resources rather than their acquisition. Density of facultative endosymbionts varied largely among aphid lines but was not associated with the fitness nor metabolic rate of aphids.

This work supports the energy basis of facultative endosymbiont associated fitness costs and raises new questions about the effect of facultative endosymbionts on the energy metabolism of their host.

Latitudinal gradient in species diversity provides high niche opportunities for a range‐expanding phytophagous insect
Authors: Jones Dylan G. , Kobelt Julia , Ross Jenna M. , Powell Thomas H. Q. , Prior Kirsten M. 
Published: August 2022

Abstract

When species undergo poleward range expansions in response to anthropogenic change, they likely encounter less diverse communities in new locations. If low diversity communities provide weak biotic interactions, such as reduced competition or predation, range‐expanding species may experience high niche opportunities.

Here, we investigated if oak gall wasp communities follow a latitudinal diversity gradient (LDG) and if lower diversity communities provide weaker interactions at the poles for a range‐expanding community member, Neuroterus saltatorius.

We performed systematic surveys of gall wasps on a dominant oak, Quercus garryana, throughout most of its range, from northern California to Vancouver Island, British Columbia. On 540 trees at 18 sites, we identified 23 oak gall wasp morphotypes in three guilds (leaf detachable, leaf integral, and stem galls). We performed regressions between oak gall wasp diversity, latitude, and other abiotic (e.g. temperature) and habitat (e.g. oak patch size) factors to reveal if gall wasp communities followed an LDG. To uncover patterns in local interactions, we first performed partial correlations of gall wasp morphotype occurrences on trees within regions). We then performed regressions between abundances of co‐occurring gall wasps on trees to reveal if interactions are putatively competitive or antagonistic.

Q. garryana‐gall wasp communities followed an LDG, with lower diversity at higher latitudes, particularly with a loss of detachable leaf gall morphotypes. Detachable leaf gall wasps, including the range‐expanding species, co‐occurred most on trees, with weak co‐occurrences on trees in the northern expanded region. Abundances of N. saltatorius and detachable and integral leaf galls co‐occurring on trees were negatively related, suggesting antagonistic interactions. Overall, we found that LDGs create communities with weaker associations at the poles that might facilitate ecological release in a range‐expanding community member.

Given the ubiquity of LDGs in nature, poleward range‐expanding species are likely moving into low diversity communities. Yet, understanding if latitudinal diversity pattern provides weak biotic interactions for range‐expanding species is not well explored. Our large‐scale study documenting diversity in a related community of phytophagous insects that co‐occur on a host plant reveals that LDGs create high niche opportunities for a range‐expanding community member. Biogeographical patterns in diversity and species interactions are likely important mechanisms contributing to altered biotic interactions under range‐expansions.

AbstractObjectivesWe conducted the cross‐cultural adaptation and validation of the Leeds Satisfaction Questionnaire (LSQ) for patients with rheumatoid arthritis (RA) in Korea.MethodsThe adaptation of the LSQ from English into Korean was based on guidelines for cross‐cultural adaptation for self‐report measures. Patients with RA were recruited from an outpatient clinic of a university hospital in South Korea. Validation of the Korean‐LSQ with Rasch models was carried out using WINSTEPS. Model fit was determined by Infit and Outfit statistics (≥0.50 and ≤1.50), including the separation index (≥2.00) and reliability index (≥0.80).ResultsThe data set comprised 125 patients (82.4% female), with median (interquartile range) age 49.0 (37‐57) years, and disease duration of 2.5 (1.2‐3.8) years. The total and subscale scores of the Korean‐LSQ demonstrated excellent or good test‐retest reliability (0.88 for total, 0.71‐0.82 for subscales), and items in the scale also revealed a high internal consistency (α = 0.93). The six subscales of the Korean‐LSQ were found to have a good fit to the Rasch model and good reliability (Person separation index = 2.63 and reliability index = 0.87; item separation index = 37.03 and reliability index >0.99). In addition, the unidimensionality of the scale was confirmed by the principal component analysis based on the Rasch residuals.ConclusionFit to the Rasch model confirmed that the construct validity, reliability, and unidimensionality of the LSQ were preserved following the adaptation into Korean. The Korean‐LSQ is a valid and reliable tool for measuring satisfaction with care in Korean patients with RA.
Beads from a mediaeval pilgrim centre: Chemical composition and provenance of glass from Banganarti, Nubia, Sudan
Authors: Then‐Obłuska Joanna , Dussubieux Laure 
Published: August 2022

AbstractChristian Nubia was a region with intensive transcultural connections that are visible through the understudied overseas glass bead imports found there. This paper presents the results of an analysis of 20 glass beads from Banganarti, a Christian pilgrim site active during the Makuria kingdom (mid‐sixth to 14th centuries CE). Compositional analyses using laser ablation–inductively coupled plasma–mass spectrometry (LA‐ICP‐MS) have identified glass belonging to a number of broad compositional groups. Two beads were made of mineral soda‐lime glass, dated before the mid‐ninth century CE. Numerous beads were made from plant ash‐soda‐lime glass associated with “Mesopotamian” production dated between the eighth and 10th centuries CE. Lead‐soda‐silica glass has parallels in the ninth–10th centuries glass found in Africa and Europe. One plant ash‐soda‐lime bead was of eastern Mediterranean origin dated after the 10th century CE. Results of this study provide new evidence for provenance and chronology of glass beads available in the mediaeval Northeast Africa as well as contribute new data to the research on the pilgrim and/or trade routes of that time.

SummaryTo optimise management of severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2) infection identifying high‐risk patients and maintaining treatment dose intensity is an important issue in patients with aggressive lymphomas. In the present study, we report on the presentation, management, and outcome of an international series of 91 patients with primary central nervous system lymphoma and SARS‐CoV‐2 infection. SARS‐CoV‐2 was diagnosed before/during first‐line treatment in 64 patients, during follow‐up in 21, and during salvage therapy in six. Among the 64 patients infected before/during first‐line chemotherapy, 38 (59%) developed pneumonia and 26 (41%) did not clear the virus. Prolonged exposure to steroids before viral infection and/or treatment with high‐dose cytarabine favoured pneumonia development and virus persistence and were associated with poorer survival; 81% of patients who did not clear virus died early from coronavirus disease 2019 (COVID‐19). Vaccination was associated with lower pneumonia incidence and in‐hospital mortality. Chemotherapy was initiated/resumed in 43 (67%) patients, more commonly among patients who did not develop pneumonia, cleared the virus, or did not receive steroids during infection. Chemotherapy resumption in patients with viral persistence should be indicated cautiously as it was associated with a poorer survival (6‐month, 70% and 87%, p = 0.07). None of the 21 patients infected during follow‐up died from COVID‐19, requiring similar measures as infected subjects in the general population.
