Vibration characteristics of channel steel-concrete composite girders: An experimental and numerical analysis
Authors: Zhang Xun , Liu Ziqi , Kong Derui , Chen Tao , Zhang Jinrui
Published: March 2022

The broad application of steel and steel-concrete bridges has caused significant vibration and noise problems. Although the channel steel-concrete composite girder is a commonly used bridge type, the vibration transmission performance and structural optimization design (concrete deck, stiffeners, transverse connection components, etc.) from the perspective of vibration control have not been well studied. In this paper, experimental and numerical approaches are combined to investigate the dynamic properties of a steel-channel girder in the audible frequency range (20–2000 Hz). A steel-channel girder is tested via hammering. The effects of damping, stiffeners, and a concrete deck on structural vibration are evaluated using the finite element method. The experimental results indicate negligible differences in the vibration responses on a single plate, but large differences at different sections. The results are influenced by the effects of the distance and transmission path. The numerical results reveal that increasing the damping and stiffness (e.g., setting stiffeners) are both effective in reducing vibrations. Furthermore, increasing the stiffness has a more prominent effect on structural vibrations and their frequency dependence, whereas increasing the damping ratio can stably reduce structural vibrations. The simulation results indicate that installing a concrete deck is the most effective approach to vibration reduction, as it can decrease overall vibration by more than 10 dB. Vertical web stiffeners have stronger effects on vibration reduction than other stiffening countermeasures (e.g., transverse connection components and longitudinal bottom plate stiffeners).
Moving sonic geographies: realising the Eerie countryside in music and sound
Authors: Holloway Julian
Published: March 2022

This paper investigates how sound produces and transforms space and place as it moves and travels. In charting the movement of sound from field recording to music studio, and from rehearsal to performance space, this paper examines the aesthetic and affective geographies that are developed and the consequences of this travel. This argument is illustrated through the example of an artistic project that sought to explore the anti- or non-idyllic practice and experience of the British countryside in sonic and musical form. The notion that there are stranger and eerie, less bucolic, and more unnerving, versions of rurality formed the artistic impulse for this project. The paper explores the creative, emotional, and technical labour involved in translating this idea into sound and music. Through inspecting the processes of achieving this project, and the geographies it generated, the paper argues that it was in the translation and movement of sound through space and through different places that the project was – sometimes unexpectedly – realised. Thus, sonic atmospheres and affective charges of the eerie rural emerged because of this movement-transformation as much it did from the different creative and technical practices, and active sonic-interventions, that sought to achieve it.
Walking with amal: the politics of the stranger

Little Amal is a giant puppet who walked across Europe in 2021 to highlight the plight of child refugees. This paper reflects on my experience of her visit to Oxford, UK, critically evaluating the political potential of the event through Amal’s status as stranger and arguing that the practice of walking with Amal provides new but qualified political potency.
Three decades of statistical pattern recognition paradigm for SHM of bridges
Authors: Figueiredo Eloi , Brownjohn James
Published: March 2022

Bridges play a crucial role in modern societies, regardless of their culture, geographical location, or economic development. The safest, economical, and most resilient bridges are those that are well managed and maintained. In the last three decades, structural health monitoring (SHM) has been a promising tool in management activities of bridges as potentially it permits one to perform condition assessment to reduce uncertainty in the planning and designing of maintenance activities as well as to increase the service performance and safety of operation. The general idea has been the transformation of massive data obtained from monitoring systems and numerical models into meaningful information. To deal with large amounts of data and perform the damage identification automatically, SHM has been cast in the context of the statistical pattern recognition (SPR) paradigm, where machine learning plays an important role. Meanwhile, recent technologies have unveiled alternative sensing opportunities and new perspectives to manage and observe the response of bridges, but it is widely recognized that bridge SHM is not yet fully capable of producing reliable global information on the presence of damage. While there have been multiple review studies published on SHM and vibration-based structural damage detection for wider scopes, there have not been so many reviews on SHM of bridges in the context of the SPR paradigm. Besides, some of those reviews become obsolete quite fast, and they are usually biased towards applications falling outside of bridge engineering. Therefore, the main goal of this article is to summarize the concept of SHM and point out key developments in research and applications of the SPR paradigm observed in bridges in the last three decades, including developments in sensing technology and data analysis, and to identify current and future trends to promote more coordinated and interdisciplinary research in the SHM of bridges.

Published: March 2022

(Genome-wide Association Studies) GWAS have identified ∼42 late-onset Alzheimer’s disease (LOAD)-associated loci, each of which contains multiple single nucleotide polymorphisms (SNPs) in linkage disequilibrium (LD) and most of these SNPs are in the non-coding region of human genome. However, how these SNPs regulate risk gene expression remains unknown. In this work, by using a set of novel techniques, we identified 6 functional SNPs (fSNPs) rs9271198, rs9271200, rs9281945, rs9271243, and rs9271247 on the LOAD-associated HLA-DRB1/DQA1 locus and 42 proteins specifically binding to five of these 6 fSNPs. As a proof of evidence, we verified the allele-specific binding of GATA2 and GATA3, ELAVL1 and HNRNPA0, ILF2 and ILF3, NFIB and NFIC, as well as CUX1 to these five fSNPs, respectively. Moreover, we demonstrate that all these nine proteins regulate the expression of both HLA-DQA1 and HLA-DRB1 in human microglial cells. The contribution of HLA class II to the susceptibility of LOAD is discussed.
Design of the Optical Dual-Band Filter for Emission of Dual Fluorescein Through the Irradiation of Single Optical Source
Authors: Kwon So Yoon , Yoon Ki-Cheol , Kim Kwang Gi
Published: March 2022

In this study, a dual-band band-pass filter (BPF) is designed to separate the dual-wavelength emissions of 5-aminolevulinic acid (5-ALA) and fluorescence sodium (yellow dye). The dual-band BPF was investigated experimentally to improve its accuracy, speed, and energy efficiency in clinical settings. The possibility of dual fluorescence emissions with a single irradiation is proposed, which saves energy by producing 2 fluorescence diagnostic effects using a single piece of equipment.

Published: March 2022

Panicum miliaceum L. is a medicinally effective plant used in indigenous system of medicine for a variety of ailments. However, there is no comprehensive study explaining its effectiveness in gastrointestinal tract, respiratory, and cardiovascular system ailments. This study was designed to validate the pharmacological basis for the folkloric use of Panicum miliaceum L. in diarrhea, asthma, and hypertension. Panicum miliaceum extract was analyzed to detect the presence of bioactive compounds by HPLC. The isolated rabbit jejunum, trachea, and aorta were used for in vitro experiments using tissue bath assembly coupled with Power Lab data acquisition system to explore their relative effects. In-vivo experiments were performed for anti-diarrheal activity. HPLC analysis revealed the presence of gallic acid, butylated hydroxytoluene, catechin, and quercetin. Concentration dependent activities were observed by relaxing K+ (low) induced contractions having spasmolytic effect with EC50 = .358 ± .052, bronchodilator (EC50 = 2.483 ± .05793), and vasorelaxant (EC50 = .383 ± .063), probably due to the ATP dependent potassium channel activation. It was confirmed through pre-exposure of glibenclamide (specific ATP-dependent K+ channel blocker) having similarities with cromakalim. Pm.Cr revealed its antidiarrheal via in vivo experiments on rats. This study indicates that Panicum miliaceum has antidiarrheal, spasmolytic, bronchodilator, and vasorelaxant activities probably due to the ATP dependent K+ channel activation.
Potential Effects of Boldine on Oxidative Stress, Apoptosis, and Inflammatory Changes Induced by the Methylprednisolone Hepatotoxicity in Male Wistar Rats
Authors: Shuker Esraa , Farhood Manal , Al-Qudaihi Ghofran , Fouad Dalia
Published: March 2022

Background

Synthetic glucocorticoid therapeutic agent methylprednisolone (MPL), when used for an extended period of time at high dose, promotes the development of reactive oxygen species (ROS)-induced liver toxicity. This study investigated the role of boldine, a natural antioxidant with anti-apoptotic and anti-inflammatory properties, against MPL-induced hepatoxicity in male Wistar rats.

Methods

120 rats were divided into eight equal groups: G1 (control), G2, 3, and 4 (rats orally administered 5, 10, and 50 mg boldine/kg b.w./day; respectively, for 28 days), G5 (rats intramuscularly injected with 100 mg MPL/kg b.w. only on the last three days), G6, 7, and 8 (rats administered boldine + MPL). After the last MPL injection, rats were sacrificed at intervals of 1, 24, and 48 h.

Results

There was a significant decrease in WBCs, RBCs count, and HGB levels, as well as an increase in PLT count, ALT, AST, TG, and LDL levels, and a decrease in HDL level in serum. Oxidative stress markers levels increased at all times, and gene expression of antioxidant enzymes increased at 24h. Immunohistochemical analysis revealed that cytochrome c levels significantly increased after MPL treatment. The COMET assay revealed detectable DNA lesions. There was no immune reactivity of IL-6 expressions as an inflammatory response marker.

Conclusions

Oral administration of boldine has a modulatory protective, antioxidant, and anti-apoptotic effect against free radicals.
Newspapers as tools to promote national agenda: How Chinese Communist Party newspapers frame images of the South China Sea disputes for national and international audiences
Authors: Zhu Runping , Krever Richard
Published: March 2022

Using both quantitative and qualitative content analysis, this study investigates how two Chinese Communist Party newspapers frame the same story to international and national audiences. The empirical findings illustrate how propaganda techniques originally developed and applied in Western and democratic countries have been adopted and refined by newspapers in a state-run Communist press environment to create frames that best align with the cultural and political predispositions of domestic and international readers. The findings suggest Chinese authorities understand Western communication theory and appreciate how that theory can be applied to disseminate messages to both foreign and domestic audiences.

Authors: Lo Julia Wing Ka , Ma Joyce Lai Chong , Wong Mooly Mei Ching , Yau-Ng Monica Lai Tuen
Published: March 2022

The suspension of social services in Hong Kong during the COVID-19 pandemic increased the caregiver strain for families of adolescent children with intellectual disabilities, possibly aggravating their family relationships. This article reports on an online Multi-Family Group (MFG) conducted during the pandemic for Hong Kong Chinese families of adolescents affected by mild-to-moderate intellectual disabilities. A thematic analysis of the experiences of the participating service users revealed three positive effects of the intervention model: improved family relationships, mutual helpful influences occurring among families, and a new understanding of family members with intellectual disabilities. The therapeutic group process used to promote family development is illustrated by a group vignette. The challenges and the practical considerations for conducting an MFG online are discussed.
Live Fences as Refuges of Wild and Useful Plant Diversity: Their Drivers and Structure in Five Elevation Contrast Sites of Veracruz, Mexico
Authors: Zamora Pedraza Gregoria , Avendaño-Reyes Sergio , Coates Rosamond , Gómez Díaz Jorge Antonio , Lascurain Maite , García-Guzmán Graciela , López-Acosta Juan Carlos
Published: March 2022

Background and Research

One noteworthy element found throughout the tropical anthropogenic mosaic is the live fence, which is established within agricultural matrices and its structure within the landscape retains ecological processes, but few are recognized as elements of biological and cultural conservation.

Methods

In this study, we have researched plant diversity and anthropic management of live fences in five sites surrounded by contrasting vegetation references: Tropical evergreen forest; tropical deciduous forest; cloud forest; and pine–oak and pine forests. We recorded the type of management by interviews with peasants. We established thirty 2 × 50 m transects within each site and sampled two strata: trees and saplings. Also, we documented seed dispersal mechanism, life form, local use, and origin of each species. Importance Value Index and diversity metrics were estimated for each site.

Results

253 plant species were registered (181 genera/74 families). While fences associated with the tropical deciduous forest showed the greatest species richness (109 species), the pine forest fences showed the lowest richness (21 species). Zoochory was the main type of seed dispersal mechanism.

Conclusions

Independent to the site and the altitude, the configuration of living fences is structured by three processes: the selection of the initial trees, the availability of the arrival of zoochory species, and the tolerance of the owners for the plant species.

Implications for Conservation

Based on our results, live fences can be considered important tools for landscape management in Mexico.

Progressive damage in pretensioned and reinforced concrete plates against repeated impacts
Authors: Kumar Vimal , Iqbal Mohd. Ashraf , Mittal Achal Kumar
Published: March 2022

This study is planned to explore the performance of pretensioned concrete (PC) plates under multiple impacts. A detailed investigation has been carried out on pretensioned concrete plates (0.8 × 0.8 m2) against drop impact. The plates prepared using Mix-40 and Mix-60 grade concrete have been induced with two different levels of initial prestress, that is, 1/10 and 1/5 (i.e. level-1 and level-2) times the strength of the concrete. The PC plates have been impacted by a falling impactor (2382 N) dropped from 0.5 m height. The response of those plates has been obtained and compared with the reference RC plates. The post-impact performance of the damaged plates has been further discovered by subsequently dropping the impactor multiple times from the identical height. The FE simulations of the problem have been carried out using Johnson-Holmquist-2 and metal-plasticity constitutive models for concrete and steel, respectively. The models have been initially verified with the experimental results available in literature, and subsequently the simulations for drop impact have been carried out. The simulation results are also compared with the results of drop impact experimentations performed. In general, both the pretensioned and reinforced concrete have witnessed flexural cracks at the beginning, such that pretensioned concrete witnessed lesser cracks compared to reinforced concrete. As the number of drops increased, one major splitting crack developed only in pretensioned concrete, whereas the reinforced concrete exhibited additional punching cracks. For a given concrete grade, the pretensioned concrete level-2 witnessed the smallest damage, minimal cracks, and also minimal spalling followed by the pretensioned concrete level-1 and reinforced concrete. The reinforced concrete absorbed the minimal impact energy followed by the pretensioned concrete level-1 and level-2 under the multiple impacts. The FE simulations predicted the impact force and reaction within 11.9 and 9.9% variation, respectively, with the corresponding experimental results.

Study Design

Retrospective multicenter cohort study

Objectives

We aimed to clarify the efficacy of multimodal intraoperative neuromonitoring (IONM), especially in transcranial electrical stimulation of motor-evoked potentials (TES-MEPs) with spinal cord-evoked potentials after transcranial stimulation of the brain (D-wave) in the detection of reversible spinal cord injury in high-risk spinal surgery.

Methods

We reviewed 1310 patients who underwent TES-MEPs during spinal surgery at 14 spine centers. We compared the monitoring results of TES-MEPs with D-wave vs TES-MEPs without D-wave in high-risk spinal surgery.

Results

There were 40 cases that used TES-MEPs with D-wave and 1270 cases that used TES-MEPs without D-wave. Before patients were matched, there were significant differences between groups in terms of sex and spinal disease category. Although there was no significant difference in the rescue rate between TES-MEPs with D-wave (2.0%) and TES-MEPs (2.5%), the false-positivity rate was significantly lower (0%) in the TES-MEPs-with-D-wave group. Using a one-to-one propensity score-matched analysis, 40 pairs of patients from the two groups were selected. Baseline characteristics did not significantly differ between the matched groups. In the score-matched analysis, one case (2.5%) in both groups was a case of rescue ( P = 1), five (12.5%) cases in the TES-MEPs group were false positives, and there were no false positives in the TES-MEPs-with-D-wave group ( P = .02).

Conclusions

TES-MEPs with D-wave in high-risk spine surgeries did not affect rescue case rates. However, it helped reduce the false-positivity rate.
Impact of Earnings Management on Profitability of Commercial Banks: Evidence from India
Authors: Mangala Deepa , Singla Neha
Published: March 2022

This article assesses the impact of earnings management on bank’s current and future financial performance. A bank-specific model, invented by Beatty et al. (2002, Accounting Review, vol. 77, pp. 547–570) and modified by Mangala and Singla (2021; Vision: The Journal of Business Perspective, vol. 25, pp. 159–167), is applied to measure earnings management. Cross-sectional regression is applied to analyse the impact of earnings management on the financial performance of banks for a time period of 7 years (from 2012–2013 to 2018–2019.). The results exhibit that Indian banks actively manage earnings. Earnings management reduces current year’s return on equity, return on assets and net interest margin. Current year’s earnings management also negatively influences following 2 years’ return on equity and net interest margin. Thus, earnings management has major negative implications on banks’ financial performance, not only in the year of earnings management but also in the years to come. In order to curtail earnings management, while examining the financial statements, auditors should be vigilant, and the Reserve Bank of India (the apex regulator) should take punitive actions against such malpractices.
Omeprazole-induced galactorrhea in kidney transplant patients—a case report
Authors: Dorji Choki , Robin Farruk Ahammed , Na-Bangchang Kesara
Published: March 2022

Background

Omeprazole belongs to the pharmacological classifications of proton pump inhibitors and is a widely used medicine. All proton pump inhibitors have a common mechanism of action and are prodrugs that require activation in an acidic environment. Omeprazole is extensively metabolized in the liver by cytochrome 2C19 and cytochrome 3A4, which are responsible for drug interactions. Omeprazole-induced galactorrhea is a rare adverse event of drug metabolism and is often underreported.

Case presentation

This is a case of a 26-year-old unmarried Asian (Bhutanese) female who underwent kidney transplant and was administered standard antirejection medication (tacrolimus, prednisolone, and leflunomide) along with an antihypertensive agent. She came to the emergency department with complaints of nausea, vomiting, abdominal pain, chronic gastritis, anemia, hypertension, and loss of appetite. The tacrolimus trough level was in the subtherapeutic range at admission. The tacrolimus dose was adjusted, and oral omeprazole was administered. After 3 days, she experienced milk production from her left breast, which according to the patient was her second incidence after omeprazole ingestion.

Conclusion

Causality assessment using Naranjo’s algorithm and recovering from galactorrhea after stopping omeprazole and omeprazole rechallenge with the reappearance of galactorrhea confirmed omeprazole as the causative agent. Tacrolimus interferes with omeprazole metabolism and increases tacrolimus levels in the blood. Caution needs to be taken when omeprazole is administered with other drugs that interfere with metabolizing enzymes.
An unusual complex suicide involving a chainsaw and a hanging: a case report
Authors: Gualco Barbara , Angelino Amalia , Rensi Regina , Manetti Gloria , Focardi Martina
Published: March 2022

Background

Suicides or suicidal attempts with power tools such as band or circular saws are rarely encountered in forensic medicine practice; in the forensic literature, only a few cases have been reported. We present the case of a “combined suicide” (self-injurious actions using different methods and involving various bodily sites) carried out with uncommon deadly methods: chainsaw and hanging.

Case presentation

A 58-year-old Caucasian man was found dead by his wife, hanging from the basement ceiling of the cellar in which he lived. During the investigation of the crime scene, external examination revealed a wide incised wound in the umbilical area showing the muscular and adipose tissues below. On inspection of the garden around the courtyard, the police found a chainsaw with blood spatter on both the blade and the handle. The blade appeared to be compatible with the abdominal injuries.

Conclusions

Since the corpse presented this incised wound, it was crucial to establish the manner and the causes of death, as well as to exclude any third-party involvement. In this case, the presence of multiple injuries, potentially lethal, required a differential diagnosis between suicide or homicide. A detailed post-mortem examination, in association with a precise study of the circumstantial data, led the authors to assume that they were dealing with a “complex suicide.”
Spatially explicit estimation of soil organic carbon stock of an estuarine mangrove wetland of eastern India using elemental analysis and very-fine resolution satellite data
Authors: Datta Debajit , Bairagi Madhumita , Dey Mansa , Pal Argha Pratim , Gayen Jibananda
Published: March 2022

Background

This study estimated the total soil organic C (SOC) stock of the wetland influence zone of Bichitrapur mangroves in eastern India in a spatially explicit manner. Both spatial and vertical distribution of SOC densities with respect to land use/land cover (LULC) pattern were assessed. Subsequently, some site-specific management strategies were forwarded towards enhancement of C sequestration potential.

Methods

The changing patterns of LULC within the wetland influence zone of the site were analyzed using Landsat TM (30 m) and Pleiades-1A (2 m) imageries from 1988 to 2018. Point-specific SOC measurement was done using samples taken from four core-depth intervals (viz. D1: 0–20 cm, D2: 20–40 cm, D3: 40–70 cm, D4: 70–100 cm) at 89 locations belonging to different LULC categories. Spatial interpolation was applied on this point-based data to produce SOC density and stock models as a whole and at all core-depths. Relationships between SOC density, core-depth and present LULC were evaluated through multivariate statistical analyses.

Results

The LULC transformations during last three decades suggested the gradual growth of mangrove plantations as well as agricultural and aquacultural activities. Most amount of SOC was concentrated in D1 (37.17%) followed by D3 (26.51%), while D4 had the lowest (10.87%). The highest mean SOC density was observed in the dense mangrove patches (248.92 Mg ha−1) and the lowest mean was in the Casuarina plantations (2.78 Mg ha−1). Here, Spline method emerged as the best-fit interpolation technique to model SOC data (R2 = 0.74) and estimated total SOC stock of the entire wetland influence zone as 169,569.40 Mg and the grand mean as 125.56 Mg ha−1. Overall, LULC was inferred as a major determinant of SOC dynamics with a statistically significant effect (p < 0.001), whereas no such inference could be drawn for soil core-depth.

Conclusions

The C sequestration potential of sites such as the present one could be increased with appropriate zone-wise plantation strategies, restriction on the land conversion to aquaculture and promotion of ecotourism. Periodic monitoring through integration of geospatial techniques and elemental analyses would be immensely beneficial in this regard.

Arts-based co-production in participatory research: harnessing creativity in the tension between process and product
Authors: Phillips Louise , Christensen-Strynø Maria Bee , Frølunde Lisbeth
Published: March 2022

Background:

In participatory research approaches, co-researchers and university researchers aim to co-produce and disseminate knowledge across difference in order to contribute to social and practice change as well as research. The approaches often employ arts-based research methods to elicit experiential, embodied, affective, aesthetic ways of knowing. The use of arts-based research in co-production in participatory research is embedded in a contested discursive terrain. Here, it is embroiled in political struggles for legitimacy revolving around what counts as knowledge and whose knowledge counts.

Aims and objectives:

The aim is to present and illustrate the use of a theoretical framework for analysing the complexities of co-production in the nexus between arts and research – with a focus on the overarching tension between cultivating the collaborative, creative process and producing specific research results. The article maps out the contested discursive terrain of arts-based co-production, and illustrates the use of the theoretical framework in analysis of a participatory research project about dance for people with Parkinson’s disease and their spouses.

Methods:

The theoretical framework combines Bakhtin’s theory of dialogue, Foucault’s theory of power/knowledge and discourse, Wetherell’s theory of affect and emotion, and work in arts-based research on embodied, affective, aesthetic knowing.

Results:

The analysis shows how arts-based processes of co-production elicit embodied, emotional, aesthetic knowing and with what consequences for the research-based knowledge and other outputs generated.

Discussion and conclusions:

Trying to contribute to both research and practice entails navigating in a discursive terrain in which criteria for judging results, outputs and impact are often defined across conflicting discourses.
Macroeconomic equilibriums, crises and fiscal policy
Authors: Andersson Fredrik N.G.
Published: March 2022

Macroeconomic crises are common as well as economically, socially and politically costly. Fiscal policy plays an important role in alleviating the costs of the crisis. However, recent experiences suggest that the public finances are often unprepared for a crisis. Deficits and debt levels prior to the crisis are commonly too high, limiting the government’s ability to support the economy through the crisis and the recovery phase. In this article, I argue that theoretical macroeconomic models’ underlying assumption of a stable long-run equilibrium may partially explain why governments fail to prepare the public finances for a future crisis. In the standard equilibrium models, crises are seen as one-off events caused by external factors, which creates a false impression of long-run economic stability. The models thus indirectly indicate that there is no need to prepare for a potential crisis. Using forecast data, I demonstrate how the equilibrium perspective dominates macroeconomic thinking and how it contributes to too-high debt ratios prior to a crisis. I end the article by discussing how to design fiscal policy rules based on a crisis rather than an equilibrium perspective.
Family sociology as a theoretical enterprise? A personal reflection
Authors: Ribbens McCarthy Jane
Published: March 2022

David Morgan’s contributions to family sociology started from a direct engagement with theoretical perspectives, but his 1996 publication, Family Connections, took his family sociology in a new, somewhat ‘fuzzy’ direction. Two key motifs for his later work are the emphasis on ‘family’ as an adjective, and its fruitfulness when conjoined with the doing of ‘practices’. Yet his 1996 text also identified key theoretical themes he considered important for family sociology to retain. I trace some of the theoretical concerns that he carried forward in his later work, while drawing attention to some aspects that invite further development, including the significance of everyday family meanings, the challenge of considering ‘family practices’ beyond affluent Minority worlds, and the need to critique the ‘individual’ along with the ‘family’. I offer this discussion on the basis that family sociology is a central issue for sociology in general as a theoretical enterprise.
The precariousness of asylum-seekers’ care and support: informal care within and because of the immigration process
Authors: Herz Marcus , Andreasson Jesper , Andréasson Frida
Published: March 2022

Using ethnographic data, this article aims to analyse the provision of informal care by asylum-seekers in Sweden and how this intersects with the(ir) asylum process. The article argues that asylum-seekers are framed by the Swedish welfare system and immigration authorities as ungrievable and deportable, which not only impedes their access to formal care systems and values, but also creates a strong need for informal care. Further, it is suggested that the informal care provided by asylum-seekers should be included in current debate on informal care and its impact on people’s lives.
Perceptions of safety and experiences of gender-based violence at UK music festivals
Authors: Bows Hannah , King Hannah , Measham Fiona
Published: March 2022

Crime and safety at UK music festivals is a subject of growing concern for festival management, police and festival-goers, bolstered by increasing media coverage of incidents of sexual harassment and sexual assault. To date, however, there has been limited evidence regarding festival-goers’ experiences and perspectives concerning safety, particularly in relation to gender-based violence at music festivals. Using data from a mixed methods pilot study, this article presents the findings of a self-selecting survey of 450 festival-goers which asked respondents about their perceptions of safety and experiences of different crime and harms including gender-based violence at UK music festivals. The findings reveal that most respondents report feeling safe at festivals, but various personal, social and environmental factors may increase or reduce these feelings of safety, and these are gendered. Similarly, although experiences of acquisitive crime, hate crime and stalking were low and broadly similar for women and men, a third of women experienced sexual harassment and 8% experienced sexual assault – significantly higher than the reported levels among male respondents. We argue that festivals must work proactively with key stakeholders and agencies, as well as artists and patrons, to develop clear policies and initiatives to prevent sexual violence.

Published: March 2022

Introduction: The present systematic review aimed to compile the information available in the literature having to do with sport psychology regarding futsal and soccer players, in order to identify which psychological constructs are being investigated in these athletes and by means of which instruments and analysis techniques. Method: The search was carried out in the APA (PsycINFO), EBSCO (SportDiscus), PubMed, Web of Science, Scielo, Science Direct, Scopus, BVS and EMBASE databases, with the following descriptors: psychological construct; psychological factor; psychological variable; psychological phenomenon; soccer; futsal and athlete, in English, Spanish and Portuguese. Results: Initially, 66 studies met the established eligibility criteria. Of these, 46 studies were conducted with soccer players, 19 with futsal players and one with athletes who participate in both sports. The psychological constructs most studied in the soccer modality were anxiety, stress, motivation, coping, motivational climate, depression, self-efficacy and group cohesion. With regard to the futsal modality, the most studied psychological constructs were group cohesion, perfectionism, motivation, athlete satisfaction, leadership style, perceived parenting styles and burnout. Conclusions: Group cohesion was associated with several other psychological aspects of an individual nature, with cohesion being the construct of both modalities which is of the greatest interest to researchers possibly because it is a collective modality. It can be established that important psychological factors have not been studied in soccer and futsal modalities, especially among female athletes. Therefore, it is recommended that the research carried out with male athletes be extended to include female populations.

Electoral volatility is understood in the literature as a sign of political instability, weakening social cohesion and the declining influences of existing political parties which threatens the healthy functioning of representative democracy. In this paper, using the Pedersen Index we measure electoral volatility in Hungary at the settlement level between the last three parliamentary elections (2010, 2014 and 2018), with special attention to the geographical aspects of the phenomenon. According to our preliminary assumptions those social groups switch their votes frequently who are marginalised, therefore, the level of volatility may reflect peripheriality. Our results show that high volatility can be detected in the two opposite sides of the settlement hierarchy in Hungary: in bigger cities and smaller villages, but for very different reasons. This study gives evidence that electoral volatility can also be considered as a possible indicator in the delimitation and classification of peripheral areas and settlements. The paper aimed to contribute to the understanding of cleavage formation at the regional level by adding a spatial perspective while connecting the socioeconomic profile of the voting population and electoral volatility.

Dissecting cellulitis of the scalp is a rare inflammatory disorder of unknown etiology. It is clinically characterized by the formation of painful suppurative chronic nodules and abscesses, which are connected by fistulae that, although they can be cured, as a consequence leave patients with irreversible alopecia. Currently, there are only a few cases reported in the literature. Here we present the case of a 45-year-old patient with dissecting cellulitis of the scalp, focusing on the histopathological findings and clinicopathologic correlation.

Introduction: While upper-class men had been taking care of themselves for centuries, this changed somewhat in the first half of the 20th century. And by the 1980s the cult of the body and the metrosexual man had emerged, with a marked upsurge in male cosmetic treatments. There was also an increased demand for treatment of wrinkles such as glabellar lines or nasolabial folds.

The mathematical model of combustion for a reactive gas suspension of coal dust in a propane-air mixture is developed. The parametric study of the problem is carried out. The observed burning velocity of the propane-air mixture with an admixture of coal particles is determined. Dependences of the observed burning velocity of the propane-air gas suspension on the equivalence ratio and on the radius of the particles are obtained. It is shown that, the observed burning velocity decreases with an increase in the radius of the particles. On the contrary, with an increase in the radius of the particle, the observed burning velocity increases for high-propane mixtures. Moreover, in the case of high-propane mixtures, the observed burning velocity of the gas suspension can be increased by reducing the mass of the particles. The observed burning velocity for a propane-air mixture with particles is significantly less than that for a mixture without particles.

This paper investigates a problem of optimal design of a multi-walled cylindrical shell under axial compressive loads. The multi-walled shell consists of two load-carrying layers connected by a set of composite walls. The main structural element of the load-carrying layer is a monolayer comprising parallel-laid fibers that are interconnected by a polymer binder – a matrix. The wall represents a unidirectional composite made from the same material as the load- carrying layers. Both strength and stability constraints are taken into account during mathematical modeling. The critical load corresponding to a general form of buckling is determined by a classical formula for an orthotropic shell with “reduced” stiffnesses. The critical load corresponding to a local form of buckling is calculated using the well-known formula for a smooth orthotropic plate. The target function is the mass of the structure. The solution to the problem of optimal design of a multi-walled structure is proved to be unique. The conditions ensuring the existence of the problem solution are formulated. The example of evaluating the efficiency of reinforcing elements in a shell structure is given. The presented research results can find application in design problems for modern composite structures in rocket and space industry.

This paper deals with a problem of a laminar steady-state flow of a non-Newtonian incompressible fluid in a pipe with a sudden expansion. The flow is described by a system of dimensionless equations in terms of stream function and vorticity in a cylindrical coordinate system: an equation of vorticity transfer and Poisson's equation for stream function. Rheological properties of the medium are defined by the Ostwald-de Waele model. The problem is solved numerically. The false transient method is applied to obtain a steady-state solution to the problem. The equations are discretized in accordance with the finite-difference method based on the alternating direction scheme. The final system of equations is solved by the tridiagonal matrix algorithm. Flow structures of Newtonian, pseudoplastic, and dilatant fluids are found to include twodimensional flow zones before and after expansion plane. A recirculation region occurs in the inner corner. To assess the effect of the Reynolds number, expansion ratio, and power-law index on the lengths of the two-dimensional flow zones and recirculation region, the graphs are plotted over a wide range of variation in the parameters. Local pressure losses are presented as functions of the governing parameters of the problem.

Aluminum alloys are widely used in industry due to such parameters as low cost, high corrosion resistance, low density, and good weldability. In this regard, new aluminum alloys with improved strength and operational properties are needed. At present, it is important to increase strength properties of aluminum alloys by introducing into their melt high-melting high-modulus nano- and microparticles that can significantly refine the grain structure and contribute to the stress-strain state. As a rule, in works on the introduction of pre-synthesized refractory dispersed particles into aluminum melts, non-metallic materials, such as oxides, nitrides, carbides, and intermetallic compounds, are used. However, the effect of high-melting tungsten particles on the structure and physical and mechanical properties of aluminum alloys has been insufficiently studied. The paper investigates the effect of tungsten nanoparticles on the structure and mechanical properties of an AA5056 alloy. The structures of the AA5056-W composite and initial alloy are studied by means of optical and scanning electron microscopy. Introduction of 0.5 wt% tungsten nanoparticles does not modify the structure of the aluminum alloy, but due to dispersed hardening, it increases the hardness, yield stress, ultimate strength, and maximum deformation before metal matrix destruction.

A mathematical model of a spectral problem containing a small parameter at the higher derivatives is investigated by an asymptotic method. The expected solution and its geometric parameters are presented as formal asymptotic decompositions. As a result, the original highorder differential task is reduced to a sequence of lower order tasks. Next, the zero approximation problem under the main boundary conditions is solved, the execution of which leads to a system of linear algebraic equations containing a spectral parameter. Equating to the zero of the determinant of the resulting system gives transcendent equations for eigenvalues. The asymptotic genesis of emerging transcendental equations allows asymptotic analysis to be applied to these equations. It helps to reveal the components of the equation that make the major contribution to the spectrum formation. Graphical solutions are used as leading considerations in this analysis. As a result of the asymptotic simulation, approximate formulas for the eigenvalues of the spectral problem have been obtained.
