Abandon the Slum? Toward an Alternative Recognition of Urban Informal Dwelling
Authors: Banerjee Paroj
Published: November 2022

The focus on urban poverty in the Global South has centered on slum-centric discussions of urban marginality to explain the supposed crisis of Third World cities. Evidently, ideological and material eradication of slums is symptomatic of the erasure of urban poverty and is regarded as a developmental panacea to address all urban problems. Notwithstanding the political significance of this term to understand and respond to subaltern urbanism, the Eurocentric gaze of urban scholars and practitioners in using slum, as an analytical and developmental category, has impeded the recognition of varied forms of dwelling practices. Drawing on ethnographic fieldwork with footpath-dwelling communities in Mumbai, I argue that to understand the diversity of dwelling in the city, attention needs to be extended to what could be called non-slums, spaces that embody a set of practices and negotiations that are spatially distinct from those characterizing places officially labeled as slums and expand beyond density politics. Unlike residents of so-called slums, these groups are often dispersed and numerically weak. It is this spatial organization (or the lack of it) that shapes their everyday politics in making their place within the city. The exposed nature of their habitation makes their everyday living transient and sets forth a form of spatiality that is distinct from dense neighborhoods labeled slums. While slums are being peripheralized through various policy and state interventions, these groups continue to hold on to the urban core and in doing so produce new spatializations of poverty and varied subaltern subjectivities of dispossession and belonging.
Epicurean Critical Praxis and Philonian Metaphor in Johannine Parrhêsia
Authors: Purcell Wood Connor
Published: November 2022

The Johannine epistles contain two concepts of parrhêsia. One, which they call by name, is a boldness before God, foreign to Gentile philosophy but explored by Jewish writers. The second, which is implicit, reflects the Hellenistic philosophical traditions of frank criticism and rebuke. Johannine parrhêsia—public and oriented toward group cohesion—most closely matches that of Epicureans in its methods and goals. However, Johannine metaphorical language, though obscure, suggests Jewish roots in its preconditions for a critical community.

Authors: Ajorloo Dariush , Nazari Mostafa , Nazari Mohsen , Sepehry Naserodin , Mohammadzadeh Ardeshir
Published: November 2022

In this article, an experimentally validated new mathematical model is developed to show a vacuum box electric furnace’s thermal behavior and predict the temperature of the desired point inside it. The model is derived by extracting the equivalent electrical circuit of the system based on heat transfer principles. To show the accuracy of the model, its behavior has been evaluated by comparing it with experimental data. Then, an optimized fuzzy controller is designed using four metaheuristic algorithms, that is, genetic algorithm, harmony search, cuckoo optimization algorithm, and water cycle algorithm. The rule-base and the membership functions are optimized by these optimization algorithms with four criteria, that is, integral of absolute error, integral of square error, integral of time absolute error, and integral of time square error. The simulation results indicate that the fuzzy controllers tuned by the integral of time square error criterion get better performance, especially in genetic and water cycle algorithms. The designed controller based on the proposed model is implemented on an experimental setup. The experimental test shows a good agreement between experimental and simulation results. The obtained results show the ability of the fuzzy controller and approve that the developed model can be used for transient performance analysis of a vacuum box electric furnace and real-time controller design.

Published: November 2022

Background

Satisfactory magnetic resonance imaging (MRI) of those patients with involuntary head motion due to brain diseases is essential in avoiding missed diagnosis and guiding treatment.

Purpose

To investigate the clinical feasibility of artificial intelligence-assisted compressed sensing single-shot fluid-attenuated inversion recovery (ACS-SS-FLAIR) in evaluating patients with involuntary head motion due to brain diseases, compared with the conventional T2-FLAIR with parallel imaging (PI-FLAIR).

Material and Methods

A total of 33 uncooperative patients with brain disease were prospectively enrolled. Two readers independently reviewed images acquired with ACS-SS-FLAIR and PI-FLAIR at a 3.0-T MR scanner. In the aspects of qualitative evaluation of image quality, overall image quality and lesion conspicuity of ACS-SS-FLAIR and PI-FLAIR were assessed and then statistically compared by paired Wilcoxon rank-sum test. For quantitative evaluation, the relative contrast of lesion-to-cerebral parenchyma were calculated and compared.

Results

Overall image quality scores of ACS-SS-FLAIR evaluated by two readers were 2.94 ± 0.24 and 2.91 ± 0.29, respectively, both of which were significantly higher than that of PI-FLAIR, respectively ( P < 0.001 and <0.001). Lesion conspicuity scores of were 2.74 ± 0.47 and 2.79 ± 0.44, both of which were significantly higher than that of PI-FLAIR, respectively ( P < 0.001 and <0.001). In the quantitative evaluation for image quality, the relative contrast of lesion-to-cerebral parenchyma was 0.34 ± 0.09 in the ACS-SS-FLAIR sequence, significantly larger than that in the PI-FLAIR sequence ( P = 0.001).

Conclusion

The ACS-SS-FLAIR sequence is clinically feasible in the MRI workup of those patients with involuntary head motion due to brain diseases, showing shorter image acquisition time and better image quality compared with conventional PI-FLAIR.

Authors: Sahtout Ghaith F , Burhan Ahmad S , Nawaya Fehmieh R
Published: November 2022

Objective

To evaluate the effect of cigarette smoking on the alveolar bone thickness and density in patients undergoing leveling and alignment of crowded lower anterior teeth.

Methods

This controlled clinical trial involved 17 smokers and 17 nonsmokers with mild to moderate crowding of the anterior mandibular teeth. Two cone-beam computed tomography images of the mandible were taken before and after treatment. The length of each tooth root was calculated in each T0 image, and the root was divided into three equal regions. Three lines were drawn parallel to the line of the cementoenamel junction at these three regions of the root, and the previously drawn lines were used to measure bone thickness and bone density.

Results

The mean changes in cortical bone thickness and bone density were significantly smaller in smokers than nonsmokers. Cortical bone thickness and bone density were significantly lower after than before treatment in both smokers and nonsmokers.

Conclusion

In addition to all of its known dangers, cigarette smoking may also harm the alveolar bone by decreasing the bone thickness and density during orthodontic treatment in heavy smokers.

Published: November 2022

This comprehensive scoping review aimed to identify all up-to-date original publications relating to substitute materials used for the surgical treatment of Peyronie’s disease (PD), and characterize what material in which chronological trends were published in the current literature. Using the PCC framework (P: population, C: concept, and C: context), a search strategy was developed and used in four electronic databases, in addition to the Google scholar. All current published, in-press, and pre-print manuscripts with available English full-text were included. Eligible studies were required to be original research articles of any study design, reporting the usage of grafts on surgical treatment of PD. Included studies were reported in a narrative synthesis format. A total of 3379 articles were identified via an electronic search of databases and a total of 171 articles entered this scoping review. Most studies originated from Europe ( n = 72) and North America ( n = 66). Reports from the other continents increase in number in the 21st century. Highest number of the published papers was seen in 2001 to 2005 pentad. Autologous grafts (53.5%). Allografts (22.7%) and xenografts (15.7%) were the most frequently reported materials. Time flow of the used material and the alterations in trends for them is quite considerable. A global perspective of relevant publications on substitute materials in the surgical management of PD is presented in this review. The information in this summary may assist in establishing future research priorities in this area.

Published: November 2022

Student engagement is associated with various aspects of students’ school experiences, including student achievement, high school completion, and post-secondary success. As measurement of student engagement has grown in countries around the world, few studies have been conducted in South America. This study examined a translated version of the Student Engagement Instrument, widely used in the U.S. and other countries, in a study of 2337 adolescents in Chile. Consistent with prior research, confirmatory factor analyses revealed a six-factor solution as the best fit for the data. However, fewer items were retained than on the studies of the SEI with students in the U.S. The Future Goals and Aspirations and Extrinsic motivation subscales were associated, in expected directions, with achievement 1 year later.
Analysis of dermal exposure assessment in the US Environmental Protection Agency Toxic Substances Control Act risk evaluations of chemical manufacturing

Published: November 2022

The United States Environmental Protection Agency (EPA) regulates chemical manufacture, import, processing, distribution, use, and disposal under the 2016 amended Toxic Substances Control Act (TSCA) for the purposes of protecting the public and sensitive populations—including workers—from chemical exposure risk. The publication of several TSCA risk evaluations provided a unique opportunity to evaluate the evolving regulatory approach for assessing the dermal exposure pathway in occupational settings. In this analysis, the occupational dermal exposure assessment methods employed in several TSCA risk evaluations were assessed. Specifically, a methodology review was conducted for the occupational dermal scenarios of manufacturing and feedstock use in the risk evaluations of three chlorinated organic chemicals: trichloroethylene, carbon tetrachloride, and perchloroethylene. Additionally, alternative exposure estimates were generated using the exposure model IH SkinPermTM. The review and alternative exposure analyses indicate that the current TSCA modeling approach may generate total dermal absorbed doses for chlorinated chemical manufacturing and feedstock use scenarios that are 2- to 20-fold higher than those generated by IH SkinPerm. Best-practice recommendations developed in the methodology review support a tiered, integrated approach to dermal exposure assessment that emphasizes collecting qualitative data; employing validated, peer-reviewed models that align with current industrial practices; and gathering empirical sampling data where needed. Collaboration among industry, EPA, and other stakeholders to share information and develop a standard approach to exposure assessment under TSCA would improve the methodological rigor of, and increase confidence in, the risk evaluation results.

Authors: Kang Xu , Xia Hongping , Skudder-Hill Loren , Yin Yafu , Wang Xiaoqiang
Published: November 2022

Purpose: The purpose of this article is to explore the clinical and neuroradiologic properties of atypical teratoid/rhabdoid tumors. Methods: Data from 6 pediatric patients with atypical teratoid/rhabdoid tumors, which mainly contained the features of magnetic resonance imaging (MRI) and positron emission tomography (PET)/computed tomography (CT), was retrospectively analyzed. Follow-up was conducted in all patients through clinic services and/or telephone consultation. Results: The patients included 4 males and 2 females, aged from 3.2 to 83.1 months at the initial diagnosis. All patients had MRI scans. Two patients underwent 18F-fluorodeoxyglucose PET/CT scintigraphy preoperatively and 4 postoperatively. All primary lesions were located in the cranial cavity and the average diameter of lesions was 37.2 mm. Cerebrospinal fluid spread on enhanced T1-weighted images were found in 2 patients. Multiple metastases were found on MRI and PET/CT scans, which were located at cranial cavity, spinal cord, lung and lymph node. The primary and metastatic lesions showed evident uptake of 18F-fluorodeoxyglucose. Two patients underwent total tumor removal, and 4 patients underwent subtotal removal. None of the patients received shunt surgery. Follow-up was performed in all 6 patients. One patient survived event-free 38.4 months after resection. The mean overall survival of the remaining 5 patients was 5.1 months. Conclusion: We identified specific PET/CT and MRI features that can facilitate the recognition of atypical teratoid/rhabdoid tumors prior to biopsy.
Study on the process damping in milling of thin-walled Ti-6Al-4V workpiece: Modeling, analysis, and prediction
Authors: Li Mengyu , Zhao Wei , Li Liang , He Ning
Published: November 2022

Due to limited stiffness and wall thickness, chatter usually occurs in the milling of thin-walled components, which reduces the surface quality and machining productivity. It is well acknowledged that process damping, which results from the interference between the flank face and the machined surface, can improve the chatter stability. This paper analyzes the influence of process damping on the milling system of thin-walled Ti-6Al-4V alloy based on the Nyquist criterion and the Routh criterion. Meanwhile, a detailed and improved calculation model of the interference area is presented to promote the prediction accuracy of process damping. The comparison of computational results and experimental findings verifies the accuracy of the proposed model. The decrease of spindle speed increases the interference area as well as the total damping of the milling system. When the spindle speed is 1000 rpm, the ultimate stable axial depth of cut increases from 1.2 mm to 2.7 mm by utilizing the special designed end mills based on the presented model.
Machining error prediction scheme aided smart fixture development in machining of a Ti6Al4V slender part
Authors: Liu Shulong , Afazov Shukri , Becker Adib , Ratchev Svetan
Published: November 2022

Machining of slender (low rigidity) parts is associated with tool/workpiece deflections due to induced cutting forces resulting in machining error (dimensional inaccuracy of the machined surface). The development of smart fixtures is seen as an enabler for reduction of machining error. To reduce lead times, the smart fixtures need to be designed in an efficient way by using more virtual simulations and less physical iterations. This paper presents the development of a novel methodology for machining error prediction in milling of a fixture-workpiece system. The methodology integrates a cutting force model, a finite element based fixture-workpiece system and a multi-step error predictive approach. The methodology was first validated on a flexible thin-wall Ti6Al4V slender part where less than 6% difference was achieved between predicted and measured machining error. The difference between predicted and measured cutting forces was approximately 6%. After the gained confidence, the methodology was applied to the flexible thin-wall Ti6Al4V slender part encompassed by a fixture with three actuators acting as supports. The predicted machining error was reduced from the range of 0.2–0.33 mm (no actuators) to the range of 0.12–0.14 mm (with three actuators). This demonstrated the capability of the developed methodology to aid the design of future smart fixtures with the potential to reduce lead times during their development.
Validity of immunoglobulin-binding protein 1 as a biomarker for lupus nephritis
Authors: Ebaid Amany M , Ezzeldin Nillie , Abdelhady Enas I , Mohammed Heba A , Abdallah Alshimaa L
Published: November 2022

Background

Lupus nephritis (LN) is a major issue that adds a burden on patients with systemic lupus erythematosus (SLE). Immunoglobulin-binding protein 1 (IGBP1) is identified as a phosphoprotein that has been recently reported to be linked to the B-cell receptor complex and regulates differentiation, proliferation, apoptosis, and tolerance of B cells. Its diagnostic and/or prognostic role in LN has been highlighted only recently.

Objectives

This study aims to evaluate the relation between serum IGBP1 and SLE disease activity and/or renal activity and to investigate the validity of IGBP1 as a biomarker for LN.

Methods

96 participants were enrolled and divided into three groups: nephritis, nonnephritis, and control groups. The patients with SLE were diagnosed according to the Systemic Lupus International Collaborating Clinics classification (SLICC) criteria. The serum IGBP1 level was assayed using an enzyme-linked immunosorbent assay (ELISA). Assessments were conducted using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2k) and renal biopsy for LN patients.

Results

The nephritis and nonnephritis groups had higher IGBP1 levels than the controls; the nephritis group had the highest serum IGBP1 levels ( p < .001). Significant correlations were found between IGBP1 levels and proteinuria (r = 0.568, p = .001) and renal SLEDAI (r = 0.475, p = .006) in the nephritis group; on the other hand, the correlation of serum IGBP1 levels with SLEDAI-2K was non-significant for both groups (nephritis and nonnephritis groups). The IGBP1 levels were significantly different among histopathologic classes ( p < .001), with class V showing the highest level. Moreover, it showed a significant positive correlation with the pathologic activity index. Compared with renal SLEDAI for identifying active renal affection in patients with SLE, the serum IGBP1 level with a cut-off value of 547.45 ng/mL is a valid biomarker for detecting active nephritis with 93.8% sensitivity and 96.9% specificity.

Conclusion

The serum IGBP1 levels were high in patients with LN and were positively correlated with the pathologic activity index. The serum IGBP1 level of 547.45 ng/mL is a valid biomarker for detecting active nephritis. Thus, we recommend that clinicians monitor the serum IGBP1 level of patients with SLE to detect LN.

Authors: Vernekar Poonam , Bhandankar Manisha , Hiremath Pooja
Published: November 2022

Introduction

LATCH score is used by the health-care professionals (HCPs) to identify mothers who require assistance in breastfeeding. We conducted this study to assess if the low LATCH score can be an indicator to alert the HCPs for intervention to achieve exclusive breastfeeding (EBF) till 6 weeks and also used as an educational tool for mothers to understand and rectify their technique of breastfeeding.

Methods

In this prospective cohort study, LATCH score was assessed after delivery within 24 h, at 48 h, and at discharge. After first assessment, mothers were informed and counselled about LATCH scoring tool and their confidence was assessed using Likert scale at each time point. Follow-up was done at 6 weeks either by person at the time of immunization or through telephone to know the status of EBF and weight of the infant.

Results

A total of 251 mothers and neonates were enrolled. Prevalence of EBF was found to be 76% at 6 weeks. Overall, the median LATCH Score at 24 h was found to be 6 (2,10) and at 48 h was 7 (3,10) whereas the median LATCH score at 48 h for those delivered vaginally was 7 (4,10) and those delivered by LSCS was 6.5 (3,9) ( P < .0001). LATCH score of ≥6 at 48 h had sensitivity and specificity of 80% (confidence interval [CI] 68%, 89%) and 69% (CI 62%, 76%) respectively with area under the curve 0.81 (CI 0.74, 0.87) to predict EBF at 6 weeks. We found statistically significant change in mother’s confidence level compared from 24 h to 48 h with better LATCH score and EBF by 6 weeks after informing them about LATCH score.

Conclusion

A LATCH score of <6 at 48 h can be a significant indicator (Red Flag sign) to intervene and promote exclusive breastfeeding. LATCH scoring itself may be used as educational tool to improve the technique of breastfeeding and thus promote EBF.

Authors: Kim Min-Su , Han Mi Ah , Park Jong , Ryu So Yeon
Published: November 2022

Coronavirus disease 2019 (COVID-19) is a new infectious disease that has had a significant impact on daily life. This study investigated the effect of changes in family life due to COVID-19 on depressive mood and stress perception. We used data from the “Survey on changes in family life due to COVID-19” in Korea. The final study population comprised 1500 adults with children aged ≤19 years. Of the total respondents, 59.3% responded that depressive mood and stress had increased due to COVID-19. However, among them, 46.6% did not attempt to resolve or could not find a way to resolve their depressive mood and stress. In multiple logistic regression analyses, a decrease in household income and increased household expenditure due to COVID-19 were significantly associated with an increased risk of depressive mood and stress perception. Depressive mood and stress were significantly higher in respondents who had experienced family conflicts. These results could be used to assess changes in family life and manage mental health when a new infectious disease occurs. Therefore, it is necessary to assess the long-term effects of changes in family life due to COVID-19 on mental health.
Minimum 3-year experience with vertebral body tethering for treating scoliosis: A systematic review and single-arm meta-analysis
Authors: Zhu Feng , Qiu Xin , Liu Shunan , Man-Chee Cheung Kenneth
Published: November 2022

Purpose

Over the past 12 years, vertebral body tethering (VBT) has been gradually promoted for treating scoliosis, but there are few published studies, with only short-term follow-up. This study aimed to systematically review VBT efficacy and safety for treating scoliosis.

Methods

PubMed, Web of Science, Embase, and the Cochrane Library were searched for studies on VBT treatment of scoliosis published up to November 2021. Two researchers independently screened the literature, extracted data, and assessed the risk of bias in included studies. Data on clinical efficacy, unplanned reoperations, and complications were extracted. The meta-analysis was performed with R 4.1.0.

Results

Twenty-six studies involving 1045 patients were included in the meta-analysis. The correction rate of major curve immediately post-operation was 46.6% ± 13.8% (16%–69%) and that at final follow-up was 53.2% ± 17.9% (16%–79%). The single-arm meta-analysis results of all included studies showed that VBT was effective in general. The overall clinical success rate was 73.02% (95% confidence interval [CI]: 68.31%–78.05%). The pooled overall unplanned reoperation rate was 8.66% (95% CI: 5.53%–13.31%). The overall incidence rate of complications was 36.8% (95% CI: 23.9%–49.7%). The subgroup analysis based on follow-up time indicated that patients with follow-up time >36 months had increased clinical success rate, unplanned reoperation rate, and incidence rate of complications compared with those with <36 months’ follow-up time. The preliminary results showed that after 36 months of follow-up, only 7.17% (95% CI: 4.81%–10.55%) of patients required posterior spinal fusion (PSF) surgery and nearly 93% of patients avoided spinal fusion surgeries.

Conclusions

The current evidence from at least 3-year follow-up in different countries indicates that VBT is an effective surgical approach for treating scoliosis, with 73.88% of patients achieving clinical success. Nevertheless, about one in seven patients (15.8%) required unplanned reoperations, but only 7.17% required PSF. About half (52.17%) of the patients experienced complications. Due to the limitation of the study number and quality, our conclusion may be biased and requires verification by further studies with longer follow-up times.

Authors: Bell Erica , Pooley Amanda , Tam Philip , Boyce Philip , Bryant Richard , Porter Richard , Malhi Gin S.
Published: November 2022

Objective

Irritability is a key symptom of mood disorders and is common in adolescence; nevertheless, it is poorly understood and assessed. Research examining irritability and its relationship to mood and anxiety disorders risk factors in adolescent males is lacking. Therefore, the current study aimed to address this gap.

Method

An online survey designed to interrogate the relationship between irritability and other risk factor variables was administered to 627 adolescent males (ages 12–17). Findings were analysed statistically using MANOVAs.

Results

When divided into high and low irritability groups, higher irritability scores were significantly correlated with higher scores on all risk factor variables. Further, higher irritability scores were associated with higher scores on all variables that indicate an increased risk for development of psychological disorders, such as depression and anxiety.

Conclusion

This study is the first to focus on subjective irritability. In adolescent males, it identifies a potentially novel model of irritability’s involvement in maladaptive processes relating to emotional dysregulation, behavioural difficulties and anxiety.
A smooth-drive scheme for piezoelectric stage by coupling of stick-slip motion and inertial impact
Authors: Ning Peng , Qiao Guangda , Li Yuelong , Lu Xiaohui , Cheng Tinghai
Published: November 2022

The piezoelectric stick-slip stage is very important in industrial manufacturing and precision machining. However, due to the stick-slip principle, it is inevitable to produce backward motion, which leads to a decrease in precision and efficiency. A novel smooth-drive scheme for piezoelectric stage is proposed by coupling stick-slip motion and inertial impact in this paper. In the coupling counteract phase, the sliding friction force of stick-slip driving mechanism (SDM) is counteract by the impact force of inertial impact driving mechanism (IDM), thus eliminating the backward motion and realizing the smooth driving of the stage. The feasibility of the stage is analyzed by theoretical calculation and transient dynamics simulation. In addition, the designed stage is fabricated and conducted a complete set of experimental tests. The external dimensions of the stage is 45 mm (L) × 24 mm (W) × 22 mm (H), and the mass is 84 g. Experimental results show that the piezoelectric stage can not only achieve smooth driving, but also actively adjust the output smoothness by adjusting the excitation voltage of PZT I and PZT II. The linear fitting correlation coefficient R2 of the displacement curve can reach above 0.999, and it still keeps good smoothness at 200 Hz. The maximum vertical mass load of the stage is 4 kg, which is about 47 times the mass of the stage, and the resolution of stick-slip state is about 85 nm. The scheme has positive reference value in the field of stable and accurate positioning.
Current status and future perspective of the link of corporate social responsibility–corporate financial performance in the tourism and hospitality industry
Authors: Lee Seoki , Yeon Jihwan , Song Hyoung J.
Published: November 2022

The CSR literature has paid close attention to the effect of CSR on corporate financial performance (CFP), well-known as the CSR–CFP link. Based on the instrumental perspective perceiving CSR as an instrument for enhancing a firm’s performance, people began to see CSR as not only a good deed that benefits society but also a strategy that can benefit the corporation. To empirically test this instrumental perspective, many researchers have investigated whether a firm’s engagement in CSR activities indeed leads to improving the firm’s performance. Through such investigations, the CSR literature has acknowledged that there are still many issues to explore in the CSR–CFP link. The current study, therefore, is to investigate what has been done in the TH literature regarding the CSR–CFP link in the 2000s and further to provide future directions for the CSR–CFP link.
The relationship between occupational socialization factors and in-service physical educators’ reported use of sport education
Authors: Vasquez Martin , Wallhead Tristan L.
Published: November 2022

Extensive empirical evidence exists for how Sport Education (SE: Siedentop et al., 2020) can deliver valued student educational outcomes, yet there remains a dearth of knowledge of how in-service teachers implement the model in practice. The purpose of this study was to examine how the stages of occupational socialization predicted teachers’ reported implementation of the structural features of SE. An SE use and occupational socialization survey was developed and completed by 65 experienced teachers who had received training on using SE during their undergraduate physical education teacher education program. Respondents reported three versions of SE implementation: (a) full, (b) modified, and (c) light, with the majority of teachers reporting using either a full or modified version of SE. Professional socialization (physical education teacher education programming) was the only significant predictor of teachers’ model use. The SE features typically implemented were formal competition, team affiliation, and seasons. The more student-centered features of student roles, record keeping, and a culminating event were less frequently used during practice. Professional socialization remains the most powerful predicted on in-service teachers’ use of SE during their professional practice. Physical education teacher education programs are encouraged to explore methods to facilitate pre-service teachers’ learning of how to implement the student-centered features of SE, as this learning will likely translate into pedagogical practice in schools.
Pasung: A qualitative study of shackling family members with mental illness in Indonesia
Authors: Baklien Børge , Marthoenis Marthoenis , Aceh Arif Rahman , Thurston Miranda
Published: November 2022

Use of coercion on people with mental illness is a deeply embedded practice around the world. Not only does the practice raise human rights issues, it also leads to further mental, physical, and emotional harms. In Indonesia, ‘pasung’ is a common practice of physical restraint, which involves lay people using a variety of illegal methods to tie a person. In this article, we explore the meanings families attach to their actions when using pasung by asking the question: to what extent does the use of pasung by families emerge from socioculturally prescribed norms and conventions? To explore this question, we conducted and analysed eight interviews with family members from Nias Island, Indonesia using Giorgi's descriptive phenomenological method. Our findings reveal that pasung emerges in the disjunction between sociocultural demands and the family's capacity to meet these demands. Struggling to understand the behaviour of a family member with mental illness, the family tries to cope with neighbourhood reactions to ever more visible behavioural signs alongside managing their everyday life. These struggles, in turn, make their social situation increasingly stressful, which initiates a process of depersonalization as a response. Moreover, the prevailing sociocultural values convey a need to act according to expected norms. As such, pasung materializes as a socioculturally accepted practice that allows families to take back control in stressful social situations. In sum, when families feel overwhelming emotional stress and a sense of powerlessness, they try to resolve their situation by using pasung to regain control and thus manage their lives.
Search quality complaints and imaginary repair: Control in articulations of Google Search
Authors: Griffin Daniel , Lurie Emma
Published: November 2022

In early 2017, a journalist and search engine expert wrote about “Google’s biggest ever search quality crisis.” Months later, Google hired him as the first Google “Search Liaison” (GSL). By October 2021, when someone posted to Twitter a screenshot of misleading Google Search results for “had a seizure now what,” users tagged the Twitter account of the GSL in reply. The GSL frequently publicly interacts with people who complain about Google Search on Twitter. This article asks: what functions does the GSL serve for Google? We code and analyze 6 months of GSL responses to complaints on Twitter. We find that the three functions of the GSL are: (1) to naturalize the logic undergirding Google Search by defending how it works, (2) perform repair in responses to complaints, and (3) boundary drawing to control critique. This advances our understanding of how dominant technology companies respond to critiques and resist counter-imaginaries.
Nonlinear vibration analysis of meshing gear wheels considering the teeth elasticity
Authors: Mohajerani Shiva , Ebrahimi Saeed , Jalili Mohammad Mahdi
Published: November 2022

In this study, the nonlinear vibration of a meshing gear pair with the teeth elasticity is investigated. The elastic elements between the teeth and the body of each gear wheel are introduced to partially incorporate the teeth elasticity in the model. This model was originally considered by the second author as a rigid-elastic modeling approach of meshing gear wheels, which is well-suited for multibody systems. The contact analysis of the meshing teeth is performed using the Kelvin-Voigt method. By deriving the equations of motion for the mentioned model, the results of the numerical solution are presented. The method of multiple scales is utilized here for the first time to analytically analyze the nonlinear vibration of a gear system in which the teeth elasticity is partially incorporated by considering identical elastic elements between the teeth and the gear body. In this study, the effect of system parameters on the frequency response including the primary, sub-harmonic, and super-harmonic resonances is investigated. The results of the analytical solution show that the effect of external excitation amplitude and intensity on the system response amplitude is the same in the primary and sub-harmonic resonances. The results obtained numerically and analytically for the model have an acceptable agreement.

The low-temperature combustion (LTC) is an attractive concept that enables the modem combustion engines to move toward sustainability mainly by increasing the efficiency and decreasing the emissions. The modern combustion engines which are working based on the LTC concept have specific fuel requirements. Fuel ϕ-sensitivity is a key factor to be considered for tailoring fuels for these engines. Fuel with a high ϕ-sensitivity are more responsive to thermal or fuel stratifications; the auto-ignition properties of different air-fuel mixtures of these fuels, with different equivalence ratio (ϕ), are more diverse. This diversity provide a smoother heat release rate in stratified condition. In this study 11 different toluene–ethanol reference fuels (TERFs) in three research octane number (RON) groups of 63, 84, and 105 together with neat ethanol are evaluated. The Lund ϕ-sensitivity method is used to evaluate these fuels in a cooperative fuel research (CFR) engine. The effect of variation of intake temperature on pressure sensitivity of fuel at a constant combustion phasing is evaluated. This evaluation is performed at two intake temperature of 373 and 423 K, and the results are compared with the outcome of the Lund ϕ-sensitivity number with the intake temperature of 323 K. This study shows that the CR sensitivity response of different blends to the intake charge temperature variation depends on the fuel composition. Accumulated low temperature heat release and latent heat of vaporization. It proves that the fuel ϕ-sensitivity will vary under different thermodynamic conditions. There was a clear link between the accumulated heat released during the early reaction and CR sensitivity of the blends at different intake temperature of 373 and 423 K but the link with the latent heat of vaporization (HoV) found to be inexplicit.
Evaluation of the sample size requirements of machine learning models used in engine design and research

Published: November 2022

Machine Learning (ML) techniques have been effectively used to learn the intricate relationships between variables that play a significant role in the field of engine design. However, there are two challenges to this approach – (1) Identifying ML regression models that could capture the trends of a response variable, given a non-parametric training set of relatively small size, with an acceptable accuracy and response time, and (2) identifying the size of the dataset, with respect to the input parameters, to be used for training and validation of the ML models. There is not enough information in the literature to reach a consensus on the sampling size to be used for an engine design problem that would yield an acceptable measure of goodness-of-fit. This is evident from the varied size of the training/validation data size used within the engine research community, as will be elaborated on in the following sections. The objective of this paper is to provide an insight into the sampling size required by the different ML models to achieve an acceptable fit between the model and the data, to be used in three types of engine design/optimization problems – (1) conventional diesel combustion (CDC) engine performance over a wide range of speed and load, (2) cold-start operation of a direct-injected spark-ignition (DISI) engine, and (3) high-load performance of a dual-fuel reactivity-controlled compression ignition (RCCI) engine.

To aid in teaching dialogue skills a virtual simulator called Communicate! was developed at Utrecht University. Teachers can build scenarios for students to practice dialogues with a virtual character. In two experiments ( n  =  128 and 133, a year apart), we investigated if and how Communicate! can be an effective aid to study and practice dialogue skills, by comparing it to traditional “passive” learning tools, such as literature-study and a lecture, in an undergraduate psychology dialogue-skills course. Students were divided into four groups, two of which both read an article about conducting a bad-news dialogue and played a bad-news-dialogue-scenario (but in a different order), while the third group only played the scenario. The final group only read the article (expt. 1) or also attended a lecture on the topic (expt. 2). Playing a scenario improved performance on a different scenario played later. It increased the students’ reported engagement and motivation to learn about this topic, compared to reading the article, whereas their reported self-efficacy decreased, which may indicate a recognized learning need. It also increased the score on an MC-knowledge test on this type of dialogue. This suggests that online dialogue simulations aid studying (basic) dialogue skills, by providing flexible, authentic learning experiences.

Published: November 2022

This article describes how to develop, conduct, and write a structured literature review (SLR) and cites examples of published SLR to illustrate different perspectives on the process and contributions to the literature. We first discuss how the SLR differs from other types of reviews (i.e., integrative literature review, meta-analysis, and scoping review). Second, the process of writing an SLR is discussed across common manuscript components: (1) the research problem, (2) conceptual or theoretical framework, (3) method, (4) findings and discussion, and (5) implications. Finally, we offer implications for how the SLR can be effectively leveraged in human resource development.
The Managing Cancer and Living Meaningfully (CALM) Intervention Alleviates Chemotherapy-Related Cognitive Impairment in Patients with Breast Cancer by Modulating Pan-Immune-Inflammation Values

Published: November 2022

Background:

The number of patients with breast cancer is increasing worldwide, resulting in a growing number of patients with chemotherapy-related cognitive impairment (CRCI), which seriously affects their quality of life. CRCI is associated with inflammatory factors and systemic inflammatory markers such as pan-immune-inflammation value (PIV) and monocyte-to-lymphocyte ratio (MLR), which can reflect the level of inflammation in the body. While the Managing Cancer and Living Meaningfully (CALM) intervention has been demonstrated to alleviate CRCI in patients with breast cancer, the specific mechanism remains unclear.

Objective:

This study evaluated the impact of the CALM intervention on systemic inflammation.

Methods:

Ninety patients with breast cancer with CRCI were enrolled and randomized into care as usual (CAU) and CALM intervention groups. All patients were assessed using the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog), Mini-Mental State Exam (MMSE), and Functional Assessment of Cancer Therapy-Breast (FACT-B) before and after the CAU/CALM intervention. The blood levels of inflammatory markers were also analyzed before and after the intervention.

Results:

Compared to the CAU group, the CALM group showed significantly improved cognitive function and significantly decreased PIV ( P < .05). PIV was significantly negatively correlated with FACT-Cog ( P < .05). The levels of other inflammatory markers, including MLR, neutrophil-to-lymphocyte ratio (NLR), granulocyte-to-lymphocyte ratio (GLR), and systemic immune-inflammation index (SII), were also reduced in the CALM group.

Conclusion:

PIV is an important marker of inflammation. The CALM intervention may improve the cognitive function of patients by regulating the systemic inflammation marker PIV through the neuroimmune axis.
Resilience and Climate Disaster Management in Cities: Transformative Change and Conflicts
Authors: Gaborit Pascaline
Published: November 2022

This article considers local resilience strategies and climate disaster management response in cities, as well as their impacts in terms of climate adaptation and transformative change. It argues that the soaring use of the concept of resilience is concealing a discrepancy between the ambitions and the solutions for the implementation of better, fairer, and more trustworthy climate adaptation solutions. Cities’ stakeholders are increasingly confronted with trade-offs, while they are often ill-equipped with a lack of facilities, accessible funding, and a limited capacity to address the multiple challenges. Vulnerable populations and poorer groups remain increasingly exposed to climate disasters. The lack of clarity in land-use mechanisms, as well as the multiple obstacles to solutions for climate adaptation, is fueling social conflicts. Multi-stakeholder dialogue, cooperation, local engagement, and a renewed international attention are needed to bring about the transformative change necessary to achieve local resilience, and to generate sufficient trust in the response process to climate disasters.
Reflection Labs: A Space for Researcher Reflexivity in Participatory Collaborations

Published: November 2022

This paper introduces reflection labs as a tool for researcher reflexivity in participatory collaborations. Participatory methodologies intend to achieve equal partnerships, co-production of knowledge and empowerment processes. In this agenda, reflexivity is key, not only for analytical reasons but also to address power inequalities, challenges in the partnerships and other ethical questions. In this paper, we describe the methodological underpinnings and empirical use of a tool we call a ‘reflection lab’. In a 3-year participatory study with refugees (EMPOW), funded by the German Research Foundation, various online and offline spaces were created for reflexivity among community and academic partners. Reflection labs were developed for the academic partners. The term ‘lab’ points to the somewhat experimental nature of this space. Combining different approaches to reflexivity in creative ways, reflection labs offer a space to explore researcher subjectivities. Using field notes, minutes and analytical notes (‘memos’) as a starting point, in-depth discussions foster critical self-reflexivity and provide peer feedback and support about academic researchers’ roles in participatory collaborations. The paper includes an example of a reflection lab that was organized virtually for more than 2 years due to Corona restrictions. By combining aspects of ‘strong reflexivity’ (analyzing researcher subjectivities for epistemic purposes) and ‘ethical reflexivity’ (addressing power inequalities and socio-political implications) reflection labs provide an innovative tool for an engaged, analytical research practice that pursues participatory goals and strives for ethical conduct and accountability.
