Effectiveness of WhatsApp for Measuring Migration in Follow-Up Phone Surveys. Lessons from a Mode Experiment in Two Low-Income Countries during COVID Contact Restrictions
Authors: Ndashimye Felix , Hebie Oumarou , Tjaden Jasper
Published: July 2022

Phone surveys have increasingly become important data collection tools in developing countries, particularly in the context of sudden contact restrictions due to the COVID-19 pandemic. So far, there is limited evidence regarding the potential of the messenger service WhatsApp for remote data collection despite its large global coverage and expanding membership. WhatsApp may offer advantages in terms of reducing panel attrition and cutting survey costs. WhatsApp may offer additional benefits to migration scholars interested in cross-border migration behavior which is notoriously difficult to measure using conventional face-to-face surveys. In this field experiment, we compared the response rates between WhatsApp and interactive voice response (IVR) modes using a sample of 8446 contacts in Senegal and Guinea. At 12%, WhatsApp survey response rates were nearly eight percentage points lower than IVR survey response rates. However, WhatsApp offers higher survey completion rates, substantially lower costs and does not introduce more sample selection bias compared to IVR. We discuss the potential of WhatsApp surveys in low-income contexts and provide practical recommendations for field implementation.
Mentoring and Career Success: An Examination of Management Aspirations and Lengthy Career Interruptions
Authors: Moake Timothy R. , Dougherty Thomas W. , Dreher George F.
Published: July 2022

Mentoring is a valuable resource that enhances outcomes like career success. Applying conservation of resources theory, we examine the interaction effects of workers’ management aspirations and lengthy career interruption(s) on the mentoring-career success relationship. Utilizing 259 older professional workers, we test these relationships with both cross-sectional and time-separated data. Although the pattern of results was similar when comparing the cross-sectional data to the time-separated data, we found that relationships were stronger within the cross-sectional data, resulting in the support of two additional hypotheses. With the time-separated data, we found evidence of a three-way interaction. Specifically, mentoring is more valuable for the perceived career success of workers with higher management aspirations who had not experienced a lengthy career interruption than it is for workers with higher management aspirations who had experienced a lengthy career interruption or for workers with lower management aspirations regardless of whether they had experienced a career interruption.
Reconceptualising Work and Employment in Complex Productive Configurations

Published: July 2022

Increasingly, work and employment take place within network firms, value chains, and other organisational forms extending control beyond the firm’s legal boundaries. This article proposes a model rooted in sociological concepts (work organisation, control, and risk) to analyse how social relations of work and employment are structured, and how inequalities are manufactured, in these organisational forms. First, we change the level of analysis, moving from firm to productive configuration. Second, we propose the notion of social labour relations, to grasp the relationship between workers and any entity likely to control their conditions of work and employment. Social labour relations articulates five dimensions that could be used to compare groups of workers who are participating in the same configuration. Third, we analyse how control is exercised by which entity/entities and over which social labour relation dimension. Such an understanding is essential to provide avenues for institutional renewal: namely to reconnect control and responsibility.
Observable responses of micro-cantilever array to dynamic acoustic forces at higher mode in the broadband frequency window
Authors: Yilmaz Cagri , Sahin Ramazan , Topal Eyup Sabri
Published: July 2022

We develop a theoretical framework describing numerical approach to explore dynamic acoustic force sensitivity using micro-cantilever array in monomodal and bimodal operations. The excitation force at the second eigenmode frequency is supplied to the micro-cantilevers in monomodal operation. Since we focus on measurement sensitivity of acoustic forces at higher frequencies, deflections of micro-cantilevers at higher mode, second flexural mode, are obtained. In bimodal operations, external driving forces at the first and second eigenmode frequencies are applied simultaneously for the actuation of micro-cantilevers in an array. Depending on acoustic force strength, the application of driving force at higher eigenmode frequency in bimodal excitation scheme increases the phase sensitivity in measurement of acoustic forces within a particular frequency scope. For both excitation schemes, oscillation observables such as amplitude and phase shift are determined with respect to acoustic force frequencies for diverse acoustic force strengths. Simulation results suggest that wider high-sensitivity frequency band could be acquired, utilizing resonantly excited micro-cantilever array. For our case, we obtain the high-sensitivity frequency band of around 200–270 kHz and 440–570 kHz for the acoustic force strengths in the range of 126–1138.5 pN.
Effect of the trailing-edge flap on tones due to self-excited oscillation within the leading-edge slat cove
Authors: Lu Weishuang , Liu Peiqing , Guo Hao
Published: July 2022

To study the tonal noise characteristics of the leading-edge slat of high-lift configurations with and without a deployed trailing-edge flap, experiments are conducted in the D5 aero-acoustic wind tunnel at Beihang University. The numerical simulation method is used to obtain the necessary flow information. The experimental results show that low to mid frequency tonal noise generated by self-excited oscillation within the slat cove is dominant and its corresponding frequencies are basically unchanged whether the flap is deployed or not. However, the primary mode of self-excited oscillation within the slat cove switches to a higher one when the flap is deployed. Further analysis results demonstrate that variation of the primary mode is found to be closely related to the flow characteristics in the self-excited oscillation feedback loop. The number of the primary mode is generally proportional to the ratio between the vortex shedding frequency and the self-excited oscillation frequency. The flap being deployed results in an increase in the effective angle of attack of both the main wing and slat, which leads to a thinner separating boundary layer, thus increasing further the vortex shedding frequency and this ratio.

Objective

Men with HIV are less likely than women to know their status, be on antiretroviral therapy, and be virally suppressed. This review examined men’s community-based HIV testing services (CB-HTS) outcomes.

Design

Systematic review and meta-analysis.

Methods

We searched seven databases and conference abstracts through July 2018. We estimated pooled proportions and/or risk ratios (for meta-analyses) for each outcome using random effects models.

Results

188 studies met inclusion criteria. Common testing models included targeted outreach (e.g. mobile testing), home-based testing, and testing at stand-alone community sites. Across 25 studies reporting uptake, 81% (CI: 75–86%) of men offered testing accepted it. Uptake was higher among men reached through CB-HTS than facility-based HTS (RR = 1.39; CI: 1.13–1.71). Over 69% (CI: 64–71%) of those tested through CB-HTS were men, across 184 studies. Across studies reporting new HIV-positivity among men ( n = 18), 96% were newly diagnosed (CI: 77–100%). Across studies reporting linkage to HIV care ( n = 8), 70% (CI: 36–103%) of men were linked to care. Across 57 studies reporting sex-disaggregated data for CB-HTS conducted among key populations, men’s uptake was high (80%; CI: 70–88%) and nearly all were newly diagnosed and linked to care (95%; CI: 94–100%; and 94%; CI: 88–100%, respectively).

Conclusion

CB-HTS is an important strategy for reaching undiagnosed men with HIV from the general population and key population groups, particularly using targeted outreach models. When compared to facility-based HIV testing services, men tested through CB-HTS are more likely to uptake testing, and nearly all men who tested positive through CB-HTS were newly diagnosed. Linkage to care may be a challenge following CB-HTS, and greater efforts and research are needed to effectively implement testing strategies that facilitate rapid ART initiation and linkage to prevention services.

Published: July 2022

Background: Patients with Systemic Lupus Erythematous (SLE) are at an increased risk of infection and it is often difficult to differentiate between infection and disease activity in a febrile patient with SLE. Methods: Patients with SLE (SLICC criteria) presenting with fever between December 2018 and August 2021 were included. Neutrophil to lymphocyte ratio (NLR), NEUT-x, -y, -z indices, Erythrocyte sedimentation rate (ESR), C-reactive protein(CRP), C3, C4, anti-dsDNA antibodies, and procalcitonin(PCT) were tested in addition to investigations as per the treating physician’s discretion. Based on the clinical assessment and laboratory data, the febrile episode was classified into infection, disease flare, or both. Statistical analysis was done using GraphPad prism v8.4.2. A novel composite score was devised and validated with a calculator incorporated is a spreadsheet. The performance of a previously proposed model of duration of fever, CRP, and dsDNA (Beca et al) was evaluated and other models using PCT and NEUT-Z were explored. Results: Among 168 febrile episodes in 166 patients with SLE (25 (19–32) years), 46 were due to infection, 77 due to flare, 43 due to both, and two due to other causes. High SLEDAI 2K (0.001), anti-dsDNA ( p = 0.004), and low complements(C3, p = 0.001 and C4, p = 0.001) were characteristic of disease flare, whereas high total leukocyte count (TLC) ( p = 0.008), NLR ( p = 0.008), NEUT-x ( p = 0.001), -y ( p = 0.03), -z ( p = 0.002), CRP ( p = 0.001), and PCT ( p = 0.03) were observed with infection. A model using age, TLC, and CRP was devised using 80% of the cohort with an AUC of 0.88 (0.78–0.97) which was validated in the remaining 20% to have an AUC of 0.83(0.60–1.0). The model devised by Beca et al yielded an AUC of 0.74. Use of PCT did not improve the discrimination between flare and infection. A Model of C4 and NEUT-z analyzed in a subset performed well and needs further exploration. Conclusion: A composite score of low cost and routinely available parameters like age, TLC, and CRP gives a good discrimination between infection and flare in a febrile patient with SLE.
Statistical methods used to combine the effective reproduction number, R(t), and other related measures of COVID-19 in the UK

Published: July 2022

In the recent COVID-19 pandemic, a wide range of epidemiological modelling approaches were used to predict the effective reproduction number, R(t), and other COVID-19-related measures such as the daily rate of exponential growth, r(t). These candidate models use different modelling approaches or differing assumptions about spatial or age-mixing, and some capture genuine uncertainty in scientific understanding of disease dynamics. Combining estimates using appropriate statistical methodology from multiple candidate models is important to better understand the variation of these outcome measures to help inform decision-making. In this paper, we combine estimates for specific UK nations/regions using random-effects meta-analyses techniques, utilising the restricted maximum-likelihood (REML) method to estimate the heterogeneity variance parameter, and two approaches to calculate the confidence interval for the combined estimate: the standard Wald-type and the Knapp and Hartung (KNHA) method. As estimates in this setting are derived using model predictions, each with varying degrees of uncertainty, equal-weighting is favoured over the standard inverse-variance weighting to avoid potential up-weighting of models providing estimates with lower levels of uncertainty that are not fully accounting for inherent uncertainties. Both equally-weighted models using REML alone and REML+KNHA approaches were found to provide similar variation for R(t) and r(t), with both approaches providing wider, and therefore more conservative, confidence intervals around the combined estimate compared to the standard inverse-variance weighting approach. Utilising these meta-analysis techniques has allowed for statistically robust combined estimates to be calculated for key COVID-19 outcome measures. This in turn allows timely and informed decision-making based on all available information.
Creating Student-centred Experiences: Using Design Thinking to Create Student Engagement
Authors: Grau Stacy Landreth , Rockett Tracey
Published: July 2022

Design thinking (also known as human-centred design) is a creative problem-solving framework that focuses on developing user-centred, effective solutions to well-defined problems. Given the focus in entrepreneurship education on factors like idea generation and opportunity recognition, design thinking is especially important. While popular in several fields such as engineering, business and computer science, the authors have developed a framework to help faculties use the principles of design thinking to design more effective and highly engaging student experiences in and out of the classroom. Called the Design Framework for Student Engagement (DFSE), the article outlines the key premises of the framework as well as the tools and strategies that teachers can use to create engaging student experiences.
Analysing the Effect of Social Media on Customer Equity: A Study of Fast-food Restaurants
Authors: Zahoor Syed Zeeshan
Published: July 2022

The enormous number of social media users globally and the increased time spent by each user on social media every day have made social media an irreplaceable part of the contemporary marketing mix. Markets have become more competitive because of the new informed and empowered customers. Integrating social media into the existing marketing mix and honing its power to the optimum is the need of the hour. This has led marketers and researchers to develop a considerate understanding of social media and to analyse its effect on customers. This research paper attempts to address this contemporary paradigm and investigates the effect of social media on customer equity in fast-food restaurants. In addition, the effect of user-generated content and firm-generated content on relationship equity, value equity and brand equity is analysed. A conceptual framework is proposed in this regard, and later the relationships of this framework are evaluated with the help of data from 400 respondents. The results confirmed that social media has a positive effect on the drivers of customer equity for fast-food restaurants. While user-generated content affects brand equity the most, followed by value equity and relationship equity, firm-generated content affects relationship equity the most, followed by brand equity and value equity.

Authors: Rajani Renu L. , Heggde Githa S. , Kumar Rupesh
Published: July 2022

This review investigates the connections between chosen supply chain risks (SCR), utilization of services redesign strategies (SRS) and the effect on company execution. An empirical framework is proposed where the presence of SCRs influences the use of SRS to handle peak and lean demand has been explored. The design is to observationally analyse the connections among SCR, including request inconstancy, compelled limit, nature of conveyance, utilization of different SRS and effect of something similar on organization execution. This review depends on an overview of 439 organizations in India addressing 10 gatherings of administration businesses utilizing organized condition demonstrating (structural equation modelling (SEM)) techniques. The initial survey construct was piloted with 20 expert respondents by personal interviews, based on the inputs the final questionnaire was developed and launched to 2000 services organizations of large, medium, and small sizes in respective service industry groups in India. The outcomes show that the presence of demand variability SCR impacts utilization of SRS. The presence of the hazard of capacity constrained and nature of conveyance do not impact the utilization of SRS. There is an unexpected connection between SCR and company execution which is interceded utilizing SRS. SRS assume fluctuated part in improving various sorts of execution (SC competition, customer satisfaction and financial performance).
“A service we know was missing”: bridging the gap between referral to admission for women with moderate-severe perinatal mental health disorders at an Australian psychiatric mother-baby unit
Authors: Beaumont Tara , Sved-Williams Anne , Hill Rebecca
Published: July 2022

Objectives

Service demand at Australian psychiatric mother-baby units is high. This project aimed to test a model of care providing step up/step down support to women with moderate-severe perinatal mental health disorders awaiting hospital admission.

Method

A multi-disciplinary team was convened to provide pre-admission assessment and support to women waiting for admission, as well as post-discharge support as needed.

Results

108 referrals were managed between April – November 2021. With appropriate assessment and/or support in place, half of the women referred ( n = 54/108) were removed from the waitlist and avoided hospital admission. Service capacity indicators suggest a positive impact on referral numbers managed each week, as well as admissions per month.

Conclusion

The tested model of care appears to have successfully improved service capacity; however longer term data is recommended to determine the sustainability of the trend towards increased capacity, and the acceptability of the model of care from a consumer perspective.
Raising a Child with Craniosynostosis: Psychosocial Adjustment in Caregivers
Authors: Costa Bruna , Edwards Wendy , Wilkinson-Bell Karen , Stock Nicola Marie
Published: July 2022

Objective

While knowledge of the psychosocial impact of craniofacial conditions is growing, literature regarding the impact on parents remains limited. Parents of children born with a health condition may be at risk of experiencing a range of psychosocial challenges. This study conducted an initial investigation of psychosocial adjustment of parents of individuals with craniosynostosis to inform support provision for families.

Setting

An online UK-wide mixed-methods survey was distributed to members of Headlines Craniofacial Support.

Design

Quantitative data including standardized measures were analysed using descriptive statistics and independent samples t-tests, and inductive content analysis was used for open-ended questions.

Participants

Mothers (n  =  109) and fathers (n  =  9) of individuals ages 3 months to 49 years with single suture (63%) or syndromic (33%) craniosynostosis participated.

Results

Compared to the general population, parents of individuals with craniosynostosis reported higher levels of stress, anxiety, and depression; lower levels of resilience and optimism. Qualitative responses provided insight into parents’ experiences of birth, diagnosis, healthcare provision, familial wellbeing, and relationships. Parents reported several unmet information and support needs, alongside a range of positive outcomes.

Conclusions

This study illustrates the potential long-term psychosocial implications for parents raising children with craniosynostosis. There is a need for routine psychological screening for family members and provision of appropriate psychological support for those at risk for distress. Non-specialist health professionals may benefit from additional training about craniofacial conditions so they are better equipped to support and refer families.
Re-Classification with Outcome Correlation of Previously Diagnosed Malignant Phyllodes Tumors Applying the 2016 Consensus Guidelines
Authors: Duckworth Lauren A. , Hoda Raza , Komforti Miglena K. , Rowe J. Jordi , Downs-Kelly Erinn , McIntire Patrick J.
Published: July 2022

Background. Classification of phyllodes tumors is challenging due unclear diagnostic criteria, recently addressed by consensus review criteria. Herein, we reviewed all malignant phyllodes tumor resections and reclassified them based on the consensus guidelines, correlating with outcome. We hypothesize that application of criteria would result in a significant proportion being “down-graded” to either borderline or benign phyllodes tumor. Methods. Primary resections of malignant phyllodes tumor were reviewed by four AP board-certified, breast fellowship-trained pathologists. Morphologic variables delineated in consensus guidelines (ie stromal cellularity, cellular atypia, tumor border, presence of heterologous elements, presence of stromal overgrowth) were evaluated. Following review, cases were reclassified as benign, borderline, or malignant. Results. Upon reclassification, 20% (5/20) cases were “down-graded” to borderline phyllodes tumor while 80% (15/20) remained malignant phyllodes tumor. Two morphologic features were statistically significant including broadly infiltrating tumor border in 80% (12/15) of malignant phyllodes tumors compared to none in borderline phyllodes tumor (0/5) ( p  = 0.004) and stromal overgrowth in 67% (10/15) of malignant phyllodes tumor compared to none in borderline phyllodes tumors (0/5) ( p  = 0.03). Upon review of the pathology reports, 30% (6/20) contained all 5 histomorphologic variables delineated in the consensus review criteria. Malignant phyllodes tumor resulted in five cases with recurrence (33.3%, 5/15) and three cases with metastases (20.0%, 3/15) and borderline phyllodes tumor resulted in one case with recurrence (20.0%, 1/5) and no metastases (0/5). Conclusion. The consensus guidelines for phyllodes tumor are useful for subclassification. We hypothesize that standardize reporting of the histomorphologic variables may lead to better consensus.
Long-term Follow-up of 254 Ceramic Coated Implant (CCI) Evolution Total Ankle Replacements
Authors: van Es Laurian J. M. , van der Plaat Laurens W. , Sierevelt Inger N. , Hoornenborg Daniel , Haverkamp Daniel
Published: July 2022

Background:

The ceramic coated implant (CCI) Evolution was a third-generation implant design used in approximately 2000 total ankle replacements (TARs) between 2003 and 2016. Because this implant was abandoned, long-term follow-up studies are lacking.

Methods:

All patients undergoing TAR using a CCI prosthesis between 2004 and 2012 were included for analysis. Preoperatively the tibiotalar alignment was measured, and postoperatively the patients were followed up clinically, with radiographs and by questionnaire. The primary outcome was implant survival at 10 years of follow-up. Implant survival was also compared for (1) inflammatory joint disease vs noninflammatory joint disease and (2) preoperative tibiotalar neutral vs varus or valgus alignment. The secondary outcomes were complications, reoperations, and function (assessed by patient-reported outcome measures).

Results:

Two hundred fifty-four TARs were performed in 237 patients. Two hundred twelve additional procedures were performed to achieve stable ankles. At 10-year follow-up, the survival was 67.5%, with an average time to revision of 4.5 years. The 10-year survival of the inflammatory joint disease group was 76.8% and of the noninflammatory joint group 63.1% ( P = .44). In 248 TARs, the preoperative tibiotalar alignment was measured; (62% neutral, 25% varus, and 13% valgus), these showed 10-year survival rates of 74.7%, 48.2%, and 68.9% respectively ( P = .07). The complication rate was 54%; 37% of patients underwent reoperation. At a mean of 8.5 years, postoperative satisfaction scored an average of 7.0 (SD 2.26) on a 0- to 10-point numeric rating scale. The mean Foot and Ankle Ability Measure sports subscore was 24.7, the mean Foot and Ankle Outcome Score (FAOS) sports subscore was 42.8, and the mean 36-Item Short Form Health Survey score was 40.0. Regarding daily activities, the mean FAOS was 81.0.

Conclusion:

This is currently the sole study reporting the long-term results of the CCI prosthesis. The survival and functional outcomes were inferior to other third-generation mobile-bearing ankle implants.
Can Faking Be Measured With Dedicated Validity Scales? Within-Subject Trifactor Mixture Modeling Applied to BIDR Responses
Authors: Guenole Nigel , Brown Anna , Lim Velvetina
Published: July 2022

A sample of 516 participants responded to the Balanced Inventory of Desirable Responding (BIDR) under answer honest and instructed faking conditions in a within-subjects design. We analyze these data with a novel application of trifactor modeling that models the two substantive factors measured by the BIDR—self-deceptive enhancement (SDE) and impression management (IM), condition-related common factors, and item-specific factors. The model permits examination of invariance and change within subjects across conditions. Participants were able to significantly increase their SDE and IM in the instructed faking condition relative to the honest response condition. Mixture modeling confirmed the existence of a theoretical two-class solution comprised of approximately two thirds of “compliers” and one third of “noncompliers.” Factor scores had good determinacy and correlations with observed scores were near unity for continuous scoring, supporting observed score interpretations of BIDR scales in high-stakes settings. Correlations were somewhat lower for the dichotomous scoring protocol. Overall, results show that the BIDR scales function similarly as measures of socially desirable functioning in low- and high-stakes conditions. We discuss conditions under which we expect these results will and will not generalize to other validity scales.
Chinese Cancer Patients’ Attitudes Toward Psychotherapy and Their Willingness to Participate in Clinical Trials of Psychotherapy
Authors: Zeng Zhi , Deng Yaotiao , Liu Jie , Yang Keyi , Peng Hu , Jiang Yu
Published: July 2022

Introduction

Psychotherapy is considered part of the standard treatment of cancer in Western countries. However, there is no literature on the attitudes of Chinese cancer patients toward psychotherapy.

Methods:

In a multicenter, cross-sectional study in China, a homemade questionnaire was delivered to cancer patients. The targeted population was Chinese hospitalized cancer patients who were informed of their state of illness.

Results

Five hundred and fifty cancer patients received our questionnaire, and 83.3% completed the questionnaire. Among the 458 patients, 43.2% indicated that they had never heard of psychotherapy before the survey. However, after a brief introduction of psychotherapy, most (92.1%) cancer patients indicated that psychotherapy is essential for cancer patients, and over half of patients (57.4%) were willing to take psychotherapy on the advice of the oncologist in charge. Participants aged 45 years or younger, had a family income > 10000 yuan per month, and had an ECOG PS (Eastern Cooperative Oncology Group Performance Status) of 2-4 were more willing to receive psychotherapy. Of all patients, 59.2% and 57.6% were willing to participate in individual and group psychotherapy clinical trials, respectively. Participants who had a bachelor’s degree or higher (odds ratio, OR = 2.09) and were aged 45 years or younger (OR = 1.67) were more willing to participate in individual and group psychotherapy clinical trials, respectively.

Conclusion

The unmet psychological needs of cancer patients in China remain high, and doctors’ advice is likely to positively impact the patients’ acceptance of psychotherapy. Psychological education for Chinese cancer patients should be strengthened. More high-quality clinical trials of psychotherapy should be conducted in China to achieve greater benefits for cancer patients and their families.

Authors: VanTassel-Baska Joyce , Brown Elissa
Published: July 2022

This study assessed stakeholder perceptions across 12 gifted programs in respect to the extent to which the programs were perceived to be effective in carrying out the formal operations required of the program in the areas of identification, curriculum, instruction, and assessment. These areas were aligned to the National Association for Gifted Children’s standards. Specific questions addressed included: To what extent was the program perceived to be effective by stakeholders affected by it? To what extent did the program align with best practice standards in the field? While stakeholders were positive about the overall program, they reported that the programs needed to be improved in the following areas: identifying underrepresented populations, improving differentiated curriculum and accelerative options, providing professional learning for teachers, and using assessments appropriate for gifted learners to show growth.
Two-parameter cooperative intelligent optimal control of chaotic motion for a vibro-impact system with soft constraint
Authors: WEI Xiao-juan , ZHOU Fangwei , LI Ning-zhou , LI Deyang , DING Wang-cai
Published: July 2022

For the chaotic motion control of a single-degree-of-freedom vibro-impact system with soft constraint, two-parameter cooperative intelligent optimal control method based on LRS-QPSO (i.e., Local Rotational Search Quantum Particle Swarm Optimization) algorithm optimization SVM (i.e., Support Vector Machines) was proposed. Firstly, in the parameter plane ( ω,ζ), the motion distribution of the system and the change of the maximum Lyapunov exponent is obtained by numerical simulation, and the correlation between parameters change and the transition from chaotic motion to periodic motion is analyzed. Secondly, by introducing ω and ζ into the construction of the input variables of the SVM controller, a chaotic motion two-parameter cooperative intelligent optimal control strategy is proposed to meet the requirements of expected control objectives. Therefore, by the virtue of nonlinear mapping characteristics of SVM, the combined effects of ω and ζ on the dynamic state transition of the system can be reflected in the output variables of the controller. Finally, with single parameter ω and single parameter ζ as the research object, the bifurcation diagram, Lyapunov exponential spectrum, and controlled periodic motion orbit diagram are analyzed, and the advantages of two-parameter cooperative intelligent optimal control are compared and analyzed.

Published: July 2022

Starting with a public relations pioneer’s maxim to “listen to stakeholders,” many contemporary scholars have emphasized listening as the key to the inclusion of marginalized communities. Based on 25 in-depth interviews including 19 Black residents of Fort Worth, this study amplifies the voices of Black community members after the killing of Atatiana Jefferson in her home by a White police officer. Their perceptions of systemic racism within the city’s listening processes and their recognition of pseudo-listening and non-action provide an understanding of and suggestions for how the city government can facilitate equitable engagement.
Asymptomatic unilateral phrenic nerve palsy after bortezomib treatment in a newly diagnosed multiple myeloma patient
Authors: Coşkunpınar Muharrem , Erdoğdu Batuhan , Goker Hakan
Published: July 2022

Introduction

Bortezomib is the first chemotherapeutic agent of proteosome inhibitor class that can be used in newly diagnosed and relapsed/refractory multiple myeloma. It is well known that bortezomib has side effects such as peripheral sensory, motor, or autonomic neuropathy. In this paper, we will present our patient who developed unilateral phrenic nerve palsy as an autonomic neuropathy after six cycles of subcutaneous bortezomib treatment. This case differs from other cases in that our patient was asymptomatic.

Case report

A 57-year-old male patient was admitted with back pain and gait disturbances. In the thorax computed tomography, a soft tissue mass causing compression on the spinal canal was observed in the T12 vertebra. Bone biopsy pathology report resulted in diffuse plasma cell infiltration. The patient was diagnosed with stage ISS-3, IgG kappa type multiple myeloma.

Management and outcome

Subcutaneous bortezomib 1 × 2.2 mg (Days 1-4-8-11) + intravenous cyclophosphamide 1000 mg (Day 1) + intravenous dexamethasone 40 mg (Days 1-2-3-4) (VCD chemotherapy protocol) was started. Totally six cycles of VCD were administered. While the patient did not have any respiratory symptoms, an elevation consistent with phrenic nerve palsy was observed in the left hemidiaphragm in the thorax computed tomography that was taken during the preparation for autologous hematopoietic stem cell transplantation.

Discussion

Bortezomib is a frequently used chemotherapeutic agent in patients with multiple myeloma and care should be taken in terms of the risk of developing phrenic nerve palsy in patients. There are cases of autonomic neuropathy developing after bortezomib treatment.

Published: July 2022

Introduction

To report a late onset, deep stromal and endothelial corneal scar in a keratoconus patient after corneal collagen cross-linking (CXL).

Case description

Observational case report. A 29-year-old man with bilateral keratoconus received an accelerated (A-CXL 10*9) epithelium-off CXL procedure in the left eye. 6-months postoperatively, a 2.2 × 1.2 mm inferocentral corneal scar was detected, which was located in the posterior stroma ranging from approximately 350 µm until the endothelium, therefore was situated below the demarcation line. A topical corticosteroid treatment did not influence the magnitude or configuration of the scar. Visual acuity was never affected, which includes the examination 12 months postoperatively.

Conclusions

We report a case of a late onset deep stromal and endothelial corneal scar 6 months after accelerated CXL as postoperative complication without affecting visual acuity.

Numerical modeling of tunnel-form buildings entails the utilization of 3D finite element models consisting of large numbers of shell and fiber elements. Accordingly, the non-linear analysis of such models under seismic excitations is both time-consuming and computationally expensive, especially in the case of large scale structures. To address this challenge, this study investigates the efficiency of the Endurance Time Method (ETM) to evaluate the structural responses, location of damage initiation, and the overall performance of tunnel-form structures under the Design Basis Earthquake (DBE) hazard level. Comparison with results derived from pushover and time-history analyses indicated the acceptable accuracy of ETM with significantly less computational efforts. The computation time required for the ETM was less than 25% of pushover (until total failure of the system) and time history analyses on the five- and ten-story tunnel-form buildings. The maximum differences between the results of ETM and time history analysis used to estimate the story drifts and shear forces were 4–6% and 1–4.5%, respectively. Considering the reliability of ETM and its appropriate accuracy, this method can be considered as a suitable alternative to the conventional methods to provide a low computational cost seismic analyses framework for non-linear tunnel-form buildings and similar structural systems.
Affective design and memetic qualities: Generating affect and political engagement through bushfire TikToks
Authors: Brown Yanni , Pini Barbara , Pavlidis Adele
Published: July 2022

This article explores the affective dimensions of social media platform TikTok, and its potential as a novel form of political participation among young people. It draws on data from a sample of 24 TikToks focused on the 2019/20 Australian bushfires, as well as seven interviews with young people who create, view and share TikToks. Building on Ash’s notion of ‘affective design’, the article demonstrates how the memetic qualities of juxtaposition, whimsy and humour are utilised to enable escape and/or connection. As young people grappled with the intensity of emotions from the Australian bushfires, TikTok gave them space for the expression of complex affects through humour, whimsy, and juxtaposition.
Conversation analysis in a US Senate Judiciary hearing: Questioning Brett Kavanaugh
Authors: Kaur Taneesh
Published: July 2022

Through a ‘micro’ and ‘macro’ level analysis, this study focuses on elements of questioning and question design in the Senate Judiciary hearing conducted for Supreme Court nominee Brett Kavanaugh. Specifically, two lines of questioning are analyzed: that of Kamala Harris, D. California, and that of Ted Cruz, R. Texas. Through an analysis that builds heavily on prior research that uses Conversation Analysis (CA) to understand the news interview, this study attempts to expand such research to institutional talk done by politicians in Congress. The analysis portion of the paper investigates, on a ‘micro’ level, the linguistic elements at play in each line of questioning. In the discussion section, a ‘macro’ level analysis situates the findings of this paper within the broader US political climate among the public and in terms of the growing conservatism of the Supreme Court.
The multiple constraints of addressed questions in whole-class interaction: Responses from unaddressed pupils
Authors: Margutti Piera
Published: July 2022

This article explores pupils’ responses to addressed questions in two third-year primary school classes, organized as plenary interaction and based on the next-speaker selection. In this context, unaddressed pupils often produce responses of various kinds spontaneously, showing that the next-speaker selection per se does not exclude unaddressed pupils from participating. Analysis of the design and position of these responses show their orderly nature as mainly depending on the following dimensions: the position of the address term in the question and who has primary access to answers. Pupils’ responses display a high level of awareness of the next-speaker selection rule operating in this setting, and more globally, of the turn-taking system. This competence enables pupils to understand and navigate the other-selection rule, often gaining their right to speakership. In line with prior studies on multiparty interactions, the article shows that teachers’ questions pose multiple constraints on responses.
Flaneuring the buyosphere: A comparative historical analysis of shopping environments and phantasmagorias
Authors: Castigliano Federico
Published: July 2022

This paper proposes a comparative historical analysis of shopping environments, focusing on the aesthetic experience they offer to the consumer and underscoring their nature as phantasmagorias. At a time when digital disruption, exacerbated by the recent pandemic, has dramatically changed social habits and the cityscape, this research aims to investigate the impact of technological and social transformations on the buyosphere and the practice of shopping. The approach's original perspective looks at the close correlation between the flâneur and the consumer, examining how retail spaces in the modern metropolis have developed. The shopping experience is shown as a social ritual with complex facets, where the urban walker and the cityscape have gradually transformed, giving symbolic meaning to architectural forms and human identities. The findings of this study call for considering the opportunities and threats of the present scenario. The shift to the virtual realm has created new forms of phantasmagoria, such as the immersive experience in the brand's universe combined with omnichannel strategies. At the same time, the “retail apocalypse” and the reduction of spaces for wandering may risk limiting social encounters, the freedom of movement, and the individual's ability to interpret urban reality, elements that once defined the practice of flânerie.
Airframe noise predictions using the Ffowcs Williams-Hawkings equation
Authors: Lockard David P
Published: July 2022

This paper considers potential sources of error when using the Ffowcs Williams-Hawkings equation to make predictions of airframe noise, which entails a relatively low-speed, uniform incoming flow encountering geometry of varying complexity. Numerical simulations are used to investigate several model problems where Ffowcs Williams-Hawkings integration surfaces are placed on solid surfaces as well as in the flow. Comparisons with the pressure obtained directly from the simulations reveal that when solid surfaces are used, the acoustic calculations can produce erroneous results in upstream directions and when scattering bodies block the line of sight from observers to the source. Using solid surface input data implies ignoring all volumetric source effects, which include noise generation as well as flow effects. Nonuniform flow alone, such as is found in a steady boundary layer, was not found to be a significant source of error, so the amplitude and phase changes induced by turbulent eddies in massively separated flow regions is speculated to be the primary cause of the error.
An Anti-Deficit Investigation of Resilience Among University Students with Adverse Experiences

Published: July 2022

Experiencing extreme adversity — such as homelessness, abuse, or incarceration — creates barriers for educational success. Yet, there is a dearth of literature on the higher education pathways of students who experienced adversity (SEA). A researcher-practitioner collaboration aimed to understand the structural challenges SEA navigated on campus and the factors promoting their resilience and retention. Ten SEA-identified students participated in semi-structured in-depth interviews. Using thematic analyses, we constructed three themes describing challenges they encountered, including experiencing a lack of community, safety concerns, and stigmatization. We also noted four themes reflecting resilience, including how SEA found a sanctuary through a campus program, gave back to similar others, reframed stigmatization, and gained personal strength through networks. An anti-deficit framework helped identify how SEA are leveraging their community strengths and past experiences to thrive in institutions still not fully prepared to serve them. We offer recommendations for how institutions can be more inclusive of SEA.

Longitudinal studies have shown that children with complex trauma (i.e., exposure to multiple or repeated traumatic events of an interpersonal nature) have poorer cognitive outcomes later in life than children without complex trauma. This association may be moderated by the timing of the trauma, which may explain, in part, some heterogeneity in the findings reported across previous investigations. The objective of the systematic review and meta-analyses was to compare the cognitive outcomes of children with complex trauma and controls and to explore whether the timing of trauma (i.e., its onset and recency) moderated this association. Electronic databases (APA PsycNET, Pubmed Central, ERIC, CINAHL, Embase) and gray literature were systematically searched. To be included, studies had to (1) have a longitudinal design, (2) comprise children with complex trauma and controls, and (3) include a cognitive assessment. Thirteen studies were identified. Meta-analyses were conducted to compare children with complex trauma and controls, while subgroup analyses and meta-regressions explored the impact of potential moderators. Children with complex trauma had poorer overall cognitive functioning than controls, and the timing of trauma (early onset and, to a greater extent, recency of trauma) moderated this association. Thus, findings suggest that children with complex trauma are at risk of cognitive difficulties quickly after trauma exposure. As such, systematic neuropsychological assessment and interventions supporting the optimal development of cognitive functioning among children with complex trauma should be investigated to determine whether prompt interventions lead to better cognitive functioning.

Purpose:

Anastomotic pseudoaneurysms of transplanted kidneys are a very rare complication encountered in less than 1% of cases. They may be devastating, leading to functional impairment, kidney transplantectomy, or death. Treatment has not been standardized, with open surgical repair considered the safest procedure even if it is often complicated by bleeding and graft loss. The purpose of this case report is to describe an endovascular treatment of this condition, consisting of the combination of coil embolization and arterial stenting.

Case report:

A 61-year-old woman developed an anastomotic pseudoaneurysm 2 months after kidney transplantation, causing acute kidney injury related to ab-extrinsic stenosis of the transplant renal artery (TRA) and external iliac artery. The pseudoaneurysm was successfully treated by coil embolization, and the arterial patency was restored by the stenting of TRA and external iliac artery. The patient completely recovered kidney function, and after a 6-month-follow-up, creatinine values were stable with normal renal perfusion.

Conclusion:

Endovascular repair through coil embolization and TRA stenting can be a safe and effective option to treat anastomotic pseudoaneurysm in kidney transplant.
