An effective strategy for decreased energy consumption by using Fe3O4 + CeO2 @ POE in Cooling system
Authors: Akkaya Mustafa
Published: May 2022

With a view to decreasing the energy consumption in cooling systems, many different methods have been used at the present time. One of these methods is the addition of solid nanoparticles to the compressor lubricant in order to increase the heat transfer surface. In this context, single and hybrid nanolubricants have been prepared by adding nano-sized iron (II, III) oxide (Fe3O4) and cerium oxide (CeO2) hybrid nanoparticles into polyol ester (POE) at different mass ratios by weight. 0.3% and 0.6% by weight of single Fe3O4 and hybrid Fe3O4 + CeO2 nanoparticles were added to this colloidal suspension separately. In addition, a 0.3% volume fraction of the surfactant triton X-100 (TX-100) was added to each suspension to avoid folliculations in nanolubricants. An experimental study was conducted under two different mass fraction single and hybrid nanolubricant to compressor section of the cooling system, respectively. The maximum improvement in coefficient of performance (COP) and the decrease in compressor work were found to be as 11.84% and 16.73%, respectively, when the hybrid nanolubricant was used as compressor lubricant.
The intertextuality and interdiscursivity of “mirroring” in South Korean cyberfeminist posts
Authors: Yang Sunyoung , Lee Kathy
Published: May 2022

This study examines the phenomenon of “mirroring” used by Womad, a cyberfeminist community in South Korea. Mirroring involves the reversal of gender to spotlight misogynist practices that might otherwise go unnoticed. To better understand mirroring, we introduce selected posts from Ilbe, a male-dominant online forum, known for denigrating Korean women and then analyze Womad’s posts on similar topics following approaches in critical discourse analysis and feminist post-structuralism. Our analysis examines two main linguistic strategies of mirroring that Womad uses to disrupt gendered ideologies. First, we focus on the use of intertextuality in Womad’s posts through their adoption of Ilbe’s masculine register to combat misogyny by targeting men. Interdiscursivity is another important strategy Womad users deploy to foreground the inequities entrenched in Korea’s long-standing patriarchy. Ultimately, mirroring offers critiques of gender inequity and misogyny through active engagements with everyday linguistic practices online while opening up new possibilities for gender politics.
Does social policy change impact on politics? A review of policy feedbacks on citizens’ political participation and attitudes towards politics
Authors: Bussi Margherita , Dupuy Claire , Van Ingelgom Virginie
Published: May 2022

This article asks how the most prominent recent changes in European welfare states are relevant for citizens’ political participation and attitudes toward politics, specifically citizens’ political efficacy, political interest, political trust and attribution of responsibility. We consider changes in benefits, in the form of generosity levels and conditionality, and changes in modes of delivery, including both marketization and rescaling. Reviewing the policy feedback on mass publics literature, a mainly US-centric scholarship, the article suggests that the mostly negative impacts that are theoretically expected are to be qualified in the European contexts. The article thereby reflects on the contributions and limits to what can be learned from this body of research to illuminate European cases; and it derives a research agenda to study policy feedbacks on mass publics in western Europe.
Between the territory and the legacies: The politicization of active labour market policy in southern Europe
Authors: Giuliani Giovanni Amerigo , Raspanti Dario
Published: May 2022

The literature concerning active labour market policy (ALMP) in advanced economies during the post-Fordist Age is very informative. Nevertheless, surprisingly, we know little about ALMP politicization. By focusing on two archetypes of the Mediterranean countries, Italy and Spain, this study argues that the geographical distribution of social stratification affects ALMP politicization at the national level. Analysing the party manifestos of the main nationwide parties in the most recent electoral turnouts (2013–2019), this article shows that while the issue is highly politicized in Spain, it is almost completely neglected in Italy. We demonstrate that when outsiderness is concentrated in a delimited geographical area, as in Italy, it hinders ALMP politicization on a national level, since it becomes a regional issue. On the contrary, when it is spread across the whole national territory, as in Spain, ALMP politicization is more likely, since the issue is nationally relevant. However, the concentration of outsiders is not sufficient to trigger a change in the electoral competition dynamic and the intervening effect of policy legacy may enhance or constrain ALMP politicization.
Infocommunicative literacy: Conceptual structure and applications
Authors: Borges Jussara
Published: May 2022

The objective of this article is to contribute to the theoretical and applied development of the area of Information Literacy, considering prominent changes in the informational environment, such as the culture of participation, constant connectivity, and the emergence of content generated by artificial intelligence. It is an environment that demands information literacy, but also the ability to interact and relate: communication literacy. This article situates infocommunicative literacy theoretically, articulating the three main bases that support this study: Information Literacy, New Media Literacy (NML), and Metaliteracy. From the systematization of these concepts, a conceptual structure accompanied by application propositions is suggested.
α-2,6-sialic acid/IgG anti-dsDNA ratios correlate with human lupus disease activity and possible mechanisms: A pilot study
Authors: Liou Lieh-bang , Wang Ting-yi , Liu I-Ju , Wu Han-Chung , Ke Po-Yuan , Fang Yao-Fan , Chen Yen-Fu
Published: May 2022

Objective

To study the association of α2,6-sialic acid (SIA) content in serum IgG anti-dsDNA with human systemic lupus erythematosus disease activity index (SLEDAI) and the effect of sialylated and desialylated (deSIA) IgG anti-dsDNA on lupus B cells.

Methods

Blood from lupus patients was collected to determine the ratio of SIA in isolated IgG anti-dsDNA over serum IgG anti-dsDNA (SIA/IgG anti-dsDNA) ratios, which were plotted against SLEDAI using a receiver-operating-characteristics curve. Lupus B cells were cultured in vitro with chimeric sialylated IgG anti-dsDNA and its deSIA form. Culture supernatants were assayed for anti-inflammatory IL-10 and SIA/IgG anti-dsDNA ratios, which were compared among different pre-treatment groups using t-tests.

Results

The area-under-the-curve (AUC) for anti-dsDNA levels against SLEDAI was 0.791 positively (95% confidence interval [C.I.]: 0.699–0.884) and SIA/IgG anti-dsDNA ratios against SLEDAI yielded an AUC of 0.705 inversely (95% C.I: 0.601–0.809): not significantly different. SIA/IgG anti-dsDNA ratios discriminated significantly between patients without and patients with proteinuria ( p = .046). SIA/IgG anti-dsDNA ratios correlated significantly and positively with serum C3c and C4 levels. Pre-treatment with IgG anti-dsDNA and its immune complexes (dsDNA/IgG anti-dsDNA IC) induced higher IL-10 from lupus B cells than medium pre-treatment (most p < .01 from day 2 to day 5 culture). DeSIA IgG anti-dsDNA IC induced lower IL-10 ( p < .05) and lower SIA/IgG anti-dsDNA ratios ( p < .001) from lupus B cells than medium and dsDNA pre-treatment.

Conclusion

α2,6-SIA/IgG anti-dsDNA ratios inversely forecasted SLEDAI scores. Possible mechanisms may be due to the different effects of sialylated and deSIA IgG anti-dsDNA on lupus B cells in terms of IL-10 secretion and SIA/IgG anti-dsDNA ratios.
An experimental and finite element simulation study of moisture absorption in an ordered PVAF-reinforced thermoplastic starch composite film
Authors: Ma Hongpeng , Zhang Xin , Guo Bin , Li Panxin
Published: May 2022

A two-dimensional (2D) model was established by the finite element method to study the transient hygroscopic process and moisture-induced stress to better understand the moisture absorption microscopic process of ordered polyvinyl alcohol fiber (PVAF)-reinforced thermoplastic starch (TPS) composite films and the corresponding moisture-induced stress. The Mises stress contour of moisture distribution at five time points (36, 68, 100, 176, and 348 h) under four relative humidities (RH=57%, 75%, 84%, 98%) is demonstrated. The variation in moisture content along the two paths of width (AB) and thickness (CD) in the 2D model and the moisture-induced stress were also studied in detail. The results show that when the time t is 348 h, the saturated moisture contents along CD are 5.27, 17.22, 30.58, and 59.14%, and along AB are 5.27, 17.19, 30.57, and 59.07%. In addition, the change in moisture content, regardless of whether the path was AB or CD, mainly occurred before 176 h. The simulation results of moisture absorption are in good agreement with the experimental results. The ultimate moisture-induced stress is the largest in the fiber surroundings, which are 0.398, 1.30, 2.31, and 4.48 MPa at four RHs, respectively, and the internal moisture stress of 4.48 MPa was within the tensile strength (2–6 MPa) of PVAF/TPS (PVAF <0.89 vt%), which resulted in composite film failure. This paper provides a new way to understand the moisture absorption mechanism and explore possible methods for improving the water-resistance of TPS films.
Optimisation of Processes by Recommending Cost Reduction Strategies in Central Sterile Supply Department (CSSD) in a Tertiary Care Hospital
Authors: Da Cruz Ashmith Relia , J. Aileen
Published: May 2022

Background

Cost analysis in central sterile supply department (CSSD) helps to achieve financial sustainability and improved efficiency for optimal field operations. This research intends to propose strategies to reduce re-sterilization of CSSD items and formulate alternatives for direct purchase of consumable items by suggesting in-house manufacture of these items.

Methods

An observational prospective study using cost analysis tools such as activity-based costing and cost–benefit analysis was conducted in a tertiary care corporate hospital. Primary data collection was done with the help of semi-structured interview questions and checklist.

Results

The analysed data indicated that on an average 150 sets per month were sent back for steam re-sterilisation which incurred the cost for re-packing, re-sterilisation and re-storage. Additionally, crucial study findings indicate that gauze swabs and dressing pads (consumable items) have been consumed in large quantities per month (20,000 Qty) leading to profligacy.

Conclusion

In-house preparation of dressing pads and gauze swabs has amassed sufficient amount of savings of about ₹70,377 and ₹24,104 per month on an average with the available resources. Moreover, techniques to avoid re-sterilization will help decrease resource consumption that includes electricity and exhaustive use of manpower.
Haunted by Cultural Memory: Analysing Spectral Presence in Select Novels of Amy Tan
Authors: Bhattacharya Rima
Published: May 2022

This article depicts how Tan, following several writers of contemporary American literature, widely uses recollected cultural memories to construct ethnic ghost narratives in her novels that address the predicaments of Chinese immigrants in the US. In her novels, Tan reconstitutes cultural memories as cultural hauntings representing immigrants’ loss of identity and the repressed trauma of relocating to a new territory. Further, the notion of a matrilineal continuum in Tan’s fiction is intrinsically related to her fictional representation of cultural hauntings. Focusing on Tan’s use of ghost narratives in her novels The Joy Luck Club, The Hundred Secret Senses and The Bonesetter’s Daughter as a supernatural terrain constituted partly through collective cultural history and partly through personal memories of ancestors, this article demonstrates how such memories in being part of the Chinese American cultural unconscious assists Chinese immigrants to find a balance between their heritage and American lifestyles.

Authors: Orlik Stefanie , Barnes Caryl , Karageorge Aspasia , You Daniel , McLean Loyola M , Proctor Marie-Therese , Kornhaber Rachel , Nash Louise
Published: May 2022

Objective

Junior doctors have high rates of burnout resulting in downstream impacts on patient care. The aim of this study is to capture cross-sectional data on a cohort of psychiatry trainees. These data will be used to inform a wider project investigating psychiatry trainee mental health and wellbeing.

Method

This paper reports on the 2019 baseline data of psychiatry trainees enrolled in a formal education course at the University of Sydney, Australia. The data were collected with an online survey using a range of validated mental health and wellbeing scales. This descriptive study involved psychiatry trainees as co-designers.

Results

Our research findings are in keeping with the existing literature on the poor mental health and wellbeing of doctors with significantly higher levels of anxiety and exhaustion found in female trainees and carers. Despite this, the cohort had high scores on the flourishing scale.

Conclusions

Concern around the wellbeing of junior doctors in Australia appears justified. We need to move beyond focussing on individual action to systems-based approaches to improving wellbeing and ongoing sustainability of the psychiatry trainee workforce in NSW.
How Buddhist Monks Use Historical Narratives to Delegitimize a Dominant Institutional Logic: The Case of a Korean Buddhist Organizational Field, 1910–1962
Authors: Song Hee-Chan
Published: May 2022

Historical narrative studies suggest that history can be strategically manipulated and narrated by current actors to facilitate change. The studies emphasize that history can be used as a source of narratives to serve present purposes. Building on the studies, this research investigates how leaders use history as a set of narratives to delegitimize a dominant logic, thus facilitating institutional change. The empirical context of this study is a Korean Buddhist organizational field during and after Japanese colonization between 1910 and 1962. This context allows to examine how a group of Korean monks with a peripheral logic (meditation logic) proactively used past stories, legends, and myths to delegitimize a dominant logic (service logic). Their narrative strategies are conceptualized in this study as reviving history, stigmatizing history, and invoking leaders from the past. In integrating the findings with the relevant literature, this research aims to contribute to historical narrative and institutional research.
The Structure of the Career Decision-Making Difficulties Questionnaire Across 13 Countries
Authors: Levin Nimrod , Udayar Shagini , Lipshits-Braziler Yuliya , Gati Itamar , Rossier Jérôme
Published: May 2022

Assessing the causes of career indecision is among the first steps in career counseling. Gati et al. (1996) proposed a multidimensional taxonomy of career indecision and developed the Career Decision-Making Difficulties Questionnaire (CDDQ), consisting of 10 scales that cohere into three higher-order clusters and a total score. However, studies investigating the CDDQ reported cross-cultural variations in its factor structure. To examine the cross-cultural generalizability of the CDDQ, we compared four alternative factor models using data from 39 diverse samples from 13 countries with nine language versions ( N = 19,562). Using weighted least squares mean- and variance-adjusted estimation, a robust estimator for nonnormal data, comparison of fit indices supported the original CDDQ structure across countries and languages. These findings support the cross-cultural generalizability of the structure of the CDDQ and the use of 10 scale scores, three cluster scores, and a total score, consistent with the taxonomy underlying the CDDQ.
Tensor product model HOSVD based polytopic LPV controller for suspension anti-vibration system
Authors: Ma Fangwu , Li Jinhang , Wu Liang
Published: May 2022

This paper presents a polytopic linear parameter varying (LPV) controller design methodology for nonlinear anti-vibration suspension based on stochastic road identification. As the main nonlinear component in semi-active suspension, the continuous damping control (CDC) damper value is mapped by damping velocity and control current through a bench experiment. linear parameter varying gain-scheduled method is applied for dealing with the nonlinear deterministic model. As the uncertainties caused by road stochastic excitation to suspension cannot be ignored, it is essential to identify the excitation signal as a measurable variable parameter. Empirical-mode-decomposition (EMD) and support vector machine (SVM) are utilized to identify and classify the road stochastic signal input into standard level, so polytopic LPV controller can be designed with CDC damper velocity, control current, and road level as variable parameters. Meanwhile the exponential increase of high-order plant elements in multi-parameter LPV model makes it too complicated for real-time computing. Hence the tensor product model transformation is utilized to identify the orthogonal basis of system plant so that low-rank approximation of it can be implemented by truncated high-order singular value decomposition (T−HOSVD) method. Real-time simulation shows the performance and feasibility of controller, which can efficaciously identify the road stochastic excitation as measurable variable parameters for nonlinear suspension polytopic LPV control.
Identification of forced time-varying systems via intrinsic chirp component decomposition
Authors: Wei Sha , Ding Hu , Peng Zhike , Chen Li-Qun
Published: May 2022

Modal parameter identification is significant in the field of vibration and control for tracking structural vibrations and evaluating structural performances. A novel parameter identification method based on the intrinsic chirp component decomposition (ICCD) and the Hilbert transform is proposed for forced time-varying systems. The developed ICCD decomposes the measured response signal into a limited number of intrinsic chirp components, and instantaneous modal parameters of the system are identified by the Hilbert transform of each intrinsic chirp component. The effectiveness and the accuracy of the proposed approach are investigated in two case studies, that is, a discrete mass-spring-damper oscillator and a cantilever beam. Smooth and periodical parameter variations are discussed in each case. Comparison with the empirical mode decomposition based method validates that the proposed method has better identification ability on estimating the instantaneous natural frequency of the system with the presence of noise. Results demonstrate that the ICCD-based approach could be a reasonable alternative for identification of forced time-varying systems in a noise environment.
An investigation into the effect of resilient wheel stiffness on the dynamic behaviour of a metro vehicle running along a tangent track
Authors: Zhou Xin , Zhong Shuoqiao , Sheng Xiaozhen
Published: May 2022

Resilient wheels are extensively used for trams due to the noise reduction they can achieve. However, the effect of the resilient wheels on vehicle dynamics has not been adequately studied. An effort is presented in this paper, trying to bridge this gap. To simulate interactions between vehicle and track, the resilient wheel is modelled as a multi-rigid body system consisting of a rigid wheel core and a rigid rim between which a rubber layer is inserted. The rubber layer is regarded as three-directional spring-damper units, allowing the rim and core to have relative motions, so that the flexibility of the resilient wheel provided by the rubber layer is fully simulated. Then, the dynamics of a vehicle-track coupling system integrated with this resilient wheel model is simulated and compared with in-situ measurement. The simulation results show that, compared with a conventional solid wheel, the vertical vibration of the wheel core is much reduced in the frequency range of 70–300 Hz while the lateral vibration is much reduced in the frequency range of 90–300 Hz. The paper continues with the recommendation of the radial and axial stiffnesses, two key parameters of the resilient wheel, aiming to lower the wheel-rail contact force and carbody vibration.
Modeling the degeneration of the collagen architecture in a microstructural model of the human cornea
Authors: Pandolfi Anna , De Bellis Maria Laura , Gizzi Alessio , Vasta Marcello
Published: May 2022

We propose an enriched micromechanical model of the collagenous reinforcement of the eye stromal tissue. As a departure from an over-simplified model proposed a few years back, where collagen and chemical bonds were modeled as linear-elastic trusses, here we describe the chemical bonds by means of a more realistic generalized Lennard-Jones potential. In keeping with the original model, we disregard the multi-layer nature of the cornea and the continuum nature of the filling elastin matrix. The under-constrained locally orthogonal network of collagen fibrils is stabilized by crosslinks that provide the rigidity of the system and confer the ability to sustain the action of the intraocular pressure. In Ariza-Gracia et al., it has been shown that the weakening and the bulging of the cornea due to ectasia can be ascribed to the reduction of the density of the chemical bonds. The introduction of a pseudo-chemical potential supplies a more realistic model: any mechanical, enzymatic, or chemical cause of the degradation of the tissue observed in ectasia can be effectively introduced in a multi-physic potential, disregarding the adoption of phenomenological models. In numerical calculations, the high non-linearity of the model is suitably controlled by adopting a robust explicit solver based on dynamic relaxation.

Authors: Gilliland Samuel , Alber Sarah , Tregear Hans , Hennigan Andrew , Weitzel Nathaen
Published: May 2022

This year marked a number of milestones in critical care. As vaccines for the SARS-CoV-2 virus became widely available and were confirmed to be exceptionally effective against severe illness and hospitalization, we were then faced with new variants and the resource-intense responses necessary to combat them. Despite challenges new and old, we have persevered and continued to provide excellent care to our patients while pushing the boundaries of clinical research. This article is a collection of studies published in 2021 relevant to critical care, with a specific focus on cardiothoracic critical care. To ignore the impact of the COVID-19 pandemic would do a disservice to our colleagues, many of whom have made incredible breakthroughs in novel therapies to the coronavirus, and yet we present additional themes of delirium, acute kidney injury, lung transplant, advances in ECMO as well as biomarkers of sepsis.

Published: May 2022

The Expert Panel for Cosmetic Ingredient Safety (Panel) reviewed the safety of 12 Rosa canina-derived ingredients, which are reported to function as skin conditioning agents, fragrance ingredients, cosmetic astringents, anti-acne agents, abrasives, humectants, and exfoliants in cosmetic products. Because final product formulations may contain multiple botanicals, each containing the same constituents of concern, formulators are advised to be aware of these constituents and to avoid reaching cumulative levels that may be hazardous to consumers. The Panel reviewed relevant data relating to the safety of these ingredients and concluded that these ingredients are safe in the present practices of use and concentration described in this safety assessment when formulated to be non-irritating and non-sensitizing.
Glocalization in Service Cultures: Tensions in Customers’ Service Expectations and Experiences
Authors: Helkkula Anu , Arnould Eric , Chen An
Published: May 2022

In the global world, service cultures interact. The co-shaping interaction of local and global service cultures is a form of glocalization. In China, interaction between traditional Chinese medicine (TCM) and Western medicine (WM) has produced glocalized versions of both services. Through analysis of customers’ experience of healthcare service in southwestern China, this paper addresses two research questions: What distinctive cultural resources do informants associate with WM and TCM? And how do tensions emerge in the contrast between customers’ expected and experienced cultural resources in glocalized healthcare service? The resource integration construct provides theoretical language to analyze customers’ service experiences in glocalized service cultures. One theoretical contribution resulting from this analysis is showing that culturally specific resources embedded in service systems emerge phenomenologically through resource integration in customers’ experiences. A second theoretical contribution resulting from this analysis is demonstrating how the mix of culturally specific resources from two glocalized services causes tensions and effects how experience is interpreted and valued. The article’s managerial contribution is a four-step culture-comparative resource framework. The framework can help managers identify tensions in customer expectations and experiences in glocalized service and identify needed changes to facilitate customers’ positive service experiences.
Experimental and numerical study on the low-velocity impact response of thermoplastic composite corrugated sandwich panels
Authors: Pan Xin , Chen Liming , Liu Houchang , Qin Weiming , Du Bing , Li Weiguo
Published: May 2022

Composite corrugated sandwich structures have a wide range of applications in aerospace field, and the loss of structural load carrying capacity due to low-velocity impact damage has become one of the main threats in practical applications. In this study, the impact resistance of corrugated sandwich panels prepared from thermoplastic composites (TPC) under low-velocity impact loading was investigated. Through a series of drop-weight experiments and finite element simulations, the impact response process and damage morphology of the thermoplastic composite sandwich panels were obtained, and the effects of different impact energy and different core arrangements on the energy absorption performance of the structure were explored. Finally, a parametric analysis of the perpendicularly-arranged double-layered corrugated sandwich panel was carried out. The results show that thermoplastic composite sandwich panels exhibit an overall collapse response rather than localised damage, and the structure maintains good integrity and stability. The perpendicularly-arranged sandwich panels rely on the orthogonal configuration characteristics to provide optimum impact load carrying capacity, their impact resistance can be further improved by increasing the thickness of top face-sheet and reducing the thickness of the middle face-sheet at the same time. This provides a basis for promoting the application of TPC in engineering and the design of sandwich structures.
A GAVeCeLT bundle for central venous catheterization in neonates and children: A prospective clinical study on 729 cases
Authors: Pittiruti Mauro , Celentano Davide , Barone Giovanni , D’Andrea Vito , Annetta Maria Giuseppina , Conti Giorgio
Published: May 2022

Background:

In the pediatric patient, central venous catheterization may be associated with relevant complications. Though, most of them may be prevented by a wise choice of materials, methods, and techniques. Evidence-based insertion bundles for central venous catheterization have been developed in the adult patient, but not in neonates and children.

Methods:

The Italian Group for Long Term Venous Access Devices (GAVeCeLT) has developed an insertion bundle for central venous catheterization in neonates, infants, and children, which includes seven evidence-based strategies: (1) preprocedural ultrasound evaluation, (2) appropriate aseptic technique, (3) ultrasound guided venipuncture, (4) intraprocedural tip location by non-radiological methods, (5) proper choice of the exit site by tunneling, (6) sutureless securement, and (7) protection of the exit site using glue and transparent membranes. The effectiveness and safety of this bundle has been tested in a prospective study.

Results:

All neonates, infants and children requiring a non-emergency central line (except for umbilical venous catheters and epicutaneo-cava catheters) were included in the study. Out of 729 central line insertions, there were no immediate complications (no pneumothorax, no arterial puncture, no malposition); the incidence of early and late complications (local ecchymosis, dislodgment, local pain, exit site infection) was 3.7%; in the first 2 weeks after insertion, no catheter-related bacterial infection or catheter-related thrombosis was recorded.

Conclusion:

The results of this prospective study strongly validate the hypothesis that an insertion bundle is highly effective in optimizing the safety of the maneuver, reducing immediate, early, and late complications.
“Music is…”?! Significations attributed by middle school students to the notion of music
Authors: Reis Leandro Augusto dos , Oliveira Francismara Neves de
Published: May 2022

This article presents the data of the significations attributed by students from the eighth year of Middle School to the notion of Music. Anchored in the Piagetian clinical–critical method and in the contribution of Genetic Epistemology, the research was carried out in a public school in the city of Londrina, Paraná, with the participation of 12 students. The results indicate that the notions of music are linked to the understanding of the social reality constructed by the participants. For this reason, by considering such constructive processes, through which social reality can be constantly signified by students, we aim to create opportunities for musical-pedagogical actions that favor the expansion of the idea of music and its domains.
Trends in adolescent psychosomatic complaints: a quantile regression analysis of Swedish HBSC data 1985–2017
Authors: Högberg Björn , Strandh Mattias , Johansson Klara , Petersen Solveig
Published: May 2022

Background and aims:

According to recent criticism, survey-based measures of adolescent psychosomatic complaints have poor content validity insofar as they conflate trivial with severe complaints. It is argued that this means that estimates of prevalence and trends in complaints may reflect trivial complaints that are not indicators of health problems. In this study, two observable implications of this criticism were investigated: (a) that self-reported psychosomatic complaints should have a bimodal distribution; and (b) that the increase in complaints over time should be of approximately equal size throughout the distribution of complaints.

Methods:

Three decades (1985/1986–2017/2018) of repeated cross-sectional data from the Swedish Health Behaviour in School-aged Children survey were used. Psychosomatic complaints were measured using the screening instrument Health Behaviour in School-aged Children symptom checklist. Histograms, bar charts and quantile regression models were used for the analysis.

Results and conclusions:

With regard to the first implication, the results showed that the distribution of complaints was not bimodal and that there were no clusters of respondents. This suggests that binary categorisations of students can be reductive and conceal important variations across students. With regard to the second implication, the results showed that the increase in complaints was greatest among students who report frequent and co-occurring complaints. This suggests that reports of increasing complaints in adolescents cannot be explained as being primarily due to a greater inclination to report trivial complaints. It is concluded that any conflation of trivial and more severe complaints in surveys of psychosomatic complaints is not reflected in population-based estimates.
Nonlinear integrated control with friction estimation for automatic lane change on the highways
Authors: Sazgar Hadi , Khalaji Ali Keymasi
Published: May 2022

A vehicle is a highly nonlinear dynamical system with high degrees of freedom. There are also very strong couplings between the longitudinal and lateral dynamics. Therefore, the simultaneous longitudinal and lateral motion control in different road conditions is a challenging problem. This paper presents an integrated adaptive control for longitudinal and lateral vehicle guidance on the highways. The contribution of this work is the design of a robust integrated controller that can handle tyre-road friction changes with low computational cost The proposed controller can adapt to the variations of tyre and road specifications. The strength of this method is that without the use of complex models, the nonlinear tyre dynamic is considered in the design of the controller. Therefore, despite the consideration of a comprehensive nonlinear vehicle dynamic model and the ability to adapt to changes in tyre and road specifications, the computational cost of the algorithm is very small. Besides, due to the controller robustness, there are no concerns about uncertainties. To validate the proposed algorithm, a full vehicle model in CarSim software is used. In obtained results, it is assumed that the yaw rate, longitudinal and lateral acceleration signals are available and have noises. The estimation of longitudinal and lateral velocities and other vehicle states has been done using these signals. Results for different road conditions as well as various vehicle movement modes confirm that tracking of longitudinal and lateral positions has been carried out with high precision. Besides, the results show that the proposed integrated control guarantees the stability of the vehicle, it will manage the tyre-road friction changes well, and also it is resistant to unmodeled uncertainties.
Co-constructing participatory ethics to address hierarchy and inequality: Social work ethics in research practice
Authors: De Backer Mattias
Published: May 2022

Research on a sensitive and potentially stigmatising topic such as ‘radicalisation’ begs for a robust ethical framework. Ethical procedures, issuing from an institutional ethics commission, are not sufficient to manage these risks. Arguably, collaborative and participatory research is best suited to overcome the risks of doing research on such a sensitive topic as well as the hierarchy and inequality in the relationship between researchers, gatekeepers and participants. To co-construct a participatory ethical framework in this context, 22 social workers were asked about the core ethical values of their own professional context. In this paper, these social work ethics are brought in tension with the practice of doing research. The paper concludes with the insight that social work ethics are not transferrable to the research context in a straightforward manner. Hierarchy and inequality (as well as much frustration) will persist if only this strategy is adopted.
Rethinking revolutionary times
Authors: Balfour Lawrie
Published: May 2022

Massimiliano Tomba's Insurgent Universality is a stunning book. Conceptually, historically, and rhetorically innovative, it shows how popular challenges to conservative and liberal forms of state-centered politics outlive attempts to contain and repress them. Tomba's reading of revolutionary declarations and manifestos in France, Saint-Domingue, Russia, Mexico, and elsewhere recalls experimental democratic practices that can animate contemporary political thinking. After surveying some of Insurgent Universality's key contributions, I ask how Tomba's argument could be extended in relation to recent debates about the politics of memory and consider what possibilities its anti-statism forecloses. Finally, I explore what gets lost in formulations of modernity that do not come to terms with racialized forms of bondage and dispossession and invite Tomba to speculate about how radical theories of politics might navigate between romantic figurations of democratic excess, on one hand, and a tragic preoccupation with aftermaths, on the other.
A fault diagnosis method for underwater thruster based on RFR-SVM
Authors: Chu Zhenzhong , Li Zhiqiang , Gu Zhenhao , Chen Yunsai , Zhang Mingjun
Published: May 2022

A fault diagnosis method for underwater thruster based on Random Forest Regression (RFR) and Support Vector Machine (SVM) is proposed in this paper. Aiming at the problem of insufficient fault diagnosis accuracy caused by the extremely unbalanced scale of normal samples and fault samples, a data argumentation method of fault samples based on RFR is proposed. Considering the over-fitting phenomenon of machine learning in the case of small samples, tsfresh package, and kernel principal component analysis (KPCA) are used to extract features from thruster time series data, and then the SVM is used to train the thruster fault diagnosis model. Finally, the effectiveness of the proposed method is verified by experiment in a pool environment.
Centering Media Literacy and Cultural Tailoring: A Scoping Review of Interventions Used to Address Black Adolescent Intimate Partner Violence

Intimate partner violence (IPV) among Black adolescents is a critical public health issue, as they report higher levels of IPV perpetration and victimization than their counterparts from other racial groups. Although practitioners frequently implement educational programs to reduce and prevent adolescent relationship violence among adolescents, the extent to which these interventions have been culturally tailored to Black youth is unclear. The purpose of this scoping review is to investigate the nature and effects of cultural tailoring in IPV interventions delivered to Black adolescent populations as well as any critical media literacy (CML) content therein. We conducted searches of three databases for peer-reviewed research published in the United States between 2000 and 2020 that evaluated an IPV-focused educational intervention with a predominantly Black adolescent sample. A total of eight original studies met our inclusion criteria. Findings showed that five of the articles mentioned some level of cultural tailoring for the participants. However, the level and nature of that tailoring ranged widely with regard to curriculum development, staffing, and other program elements. No studies included any elements of CML education. Overall results indicate positive effects of IPV interventions on adolescents and reduced acceptance of violence in romantic relationships. This scoping review highlights a lack of clarity on methods used for cultural tailoring of curriculum based IPV interventions, vague application of social learning theoretical frameworks, and the potential benefits of CML content.

Autistic individuals are at an increased risk of experiencing victimisation. Previous reviews have focussed specific types of victimisation. Thus, a clearer picture considering the range of victimisation experiences autistic people face is required. This systematic review aims to identify the prevalence of victimisation in autistic individuals considering a variety of victimisation types (e.g., bulling, sexual victimisation, and crime) in both adults and children from clinical and community settings. Through systematic searches of relevant databases, 291 studies met the criteria for review. Of those, 34 studies met the inclusion criteria: a) quantitative studies, b) involving autistic individuals, c) reporting prevalence rates of victimisation. Meta-analysis found a pooled prevalence rate of victimisation of 44% in autistic individuals. Subgroup analysis examined moderating factors as high heterogeneity was present. This found the pooled prevalence rates for bullying to be 47%, 16% for child abuse, 40% for sexual victimisation, 13% for cyberbullying, and 84% for multiple forms of victimisation in autistic individuals, though heterogeneity remained. Correction for participants’ age, reporter used, and the population which the sample was recruited from did not reduce heterogeneity. Although heterogeneity impedes the definitive interpretation of the findings, this review illustrates the need for strategies and interventions to reduce the incidence of victimisation.

Reviews of intimate partner violence (IPV) have primarily focused on women and same-sex relationships, but little is known about the global epidemiology of IPV among people living with HIV/AIDS (PLWHA). This review employed meta-analytic approaches to determine the worldwide prevalence and factors related to different forms of IPV among PLWHA. Databases including PubMed, Cochrane review, EMBASE, Scopus, PsycINFO, CINAHL, ProQuest, and registers, were systematically reviewed until November 5, 2021. The meta-analysis was conducted using the metafor package in R software. The Newcastle Ottawa Scale and Cochrane Risk of Bias Tool version 1 were used to assess the study quality and risk of bias, respectively. A total of 49 published articles and 42,280 participants, were included in the meta-analysis. Over their lifetime, four in ten PLWHA have experienced some type of IPV. Over a quarter have experienced physical, emotional, or psychological IPV. One in five PLWHA experienced at least one form of IPV during the recall period of last year, with emotional IPV being the most prevalent. Rates of physical and any types of IPV differed substantially between IPV measurements. IPV rates also varied significantly by the study design, with physical (29%) and sexual (18%) IPV rates being more prevalent in cross-sectional studies. Public health measures are critical for preventing and combating IPV among PLWHA. Additional cross-national research using robust sampling methods is required to obtain more representative samples and thus a more reliable prevalence estimate of IPV prevalence.

Young children are at high risk of lead poisoning, which can damage early cognitive and behavioral development and have long-lasting impacts. Home environments are persistent sources of exposure for children in urban, low-income settings. Community–academic partnerships are essential for public health intervention strategies addressing residential household lead exposure, yet community organization staff and home visitors often experience strain and burnout. We describe Parenting and Lead Mitigation at Home, a multifaceted partnership project to (a) develop and implement a community-based, peer-delivered education program for parents of young children in neighborhoods at risk for home lead exposure and (b) support the home visitors delivering programming. We developed, delivered, and initially evaluated Lead 101, a lead-exposure prevention curriculum informed by the Community Organizing and Family Issues (COFI) model. The goals were to educate parents around lead exposure risks and empower parents to reduce their child’s risk. We developed a novel Reflective Practice pilot curriculum designed to provide emotional support to peer educators and community organization staff who delivered home-based programming. We trained 11 peer educators who delivered Lead 101 to 62 families. We pilot-tested the Reflective Practice curriculum with five community organization staff. The implementation process and pilot evaluation data suggest increased parent knowledge and self-efficacy regarding mitigation of home-based lead hazards, and high satisfaction with reflective practice. Using this model to develop multifaceted partnerships among universities, community-based organizations, and focal communities may facilitate community-engaged program development for families and systematic support for individuals working directly with families, thereby indirectly promoting child health and well-being.
El Cabal, Vacunas, y Donald Trump: An Analysis of Spanish-Language Disinformation Leading Up to the U.S. Capitol Insurrection

Published: May 2022

The January 6 Capitol insurrection highlighted the central role conspiracy and disinformation play in motivating political violence among the right wing in the United States. In this article, the spread of Spanish-language disinformation by right-wing media in the United States is explored from a cultural and intersectional perspective. We analyze the mythological and dramatic narratives in content from a Spanish-language conspiracy website posted between the 2020 election and the Capitol insurrection. These narratives are explored through the lens of the deep story, which is the epistemological basis of U.S. conservatism. We argue that the deep story and right-wing conspiracy culture are highly flexible and can appeal to certain non-White audiences online. We then interrogate right-wing U.S. Latina/o/x political identity through an intersectional analysis of the conspiracy culture exemplified in the disinformation from the website.
