Does process matter more for predicting trust in government? Participation, performance, and process, in local government in Japan
Authors: Goldfinch Shaun , Yamamoto Kiyoshi , Aoyagi Saizo
Published: May 2022

Trust in government and its antecedents and development remain leading policy and research concerns. Drawing on a broadly representative online survey of 3100 respondents in Japan, we examine measures of trust in three local government actors. We find political participation is not associated with trust in local government, contrary to our expectations. Civic participation is associated with trust in the mayor, but not councillors or administrators. Satisfaction with services provided by local government, and positive perceptions of policy process, are associated with trust, with interactions suggesting process is the stronger antecedent. To develop greater trust in local government, it is important that public sector actors exhibit respect for rights and follow procedure, laws, and regulations, as well as deliver positive outcomes.

Points for practitioners

Building trust in government remains a key concern for policy makers, as it is related to successful adoption of policies. Trust in local government in Japan is related to perceived performance and citizen satisfaction. Civic participation is also related to some forms of trust in government. However, possibly more important are citizen perceptions that policy processes respect rights, procedures, and laws. To increase trust in government, practitioners need to practice, and show that they practice, good processes in developing and delivering policy, and show that policy leads to better perceived outcomes.
Personal and environmental factors associated with self-reported resilience among social workers
Authors: Zychlinski Ester , Itzick Michal , Kagan Maya
Published: May 2022

Resilience is a very significant issue in the context of social work practice and therefore receives a great deal of research interest. However, certain factors and combinations of factors that could explain the variability in resilience among social workers have not yet received proper research attention. Therefore, this study aimed to investigate the contribution of several personal factors (gender and length of work experience) and environmental factors (subjection to client violence, social support, and social and economic exchange in the employee–organization relationship) to self-reported resilience among social workers in Israel. Structured questionnaires were administered to 346 social workers. The findings suggest that previous subjection to violence by clients was associated with lower levels of self-reported resilience. Perceived social support and social exchange were positively associated with self-reported resilience. However, gender, length of professional experience, and economic exchange were not significantly associated with self-reported resilience among social workers.
Raising the ‘environmental question’ in social work in Canada and Scotland
Authors: Wilson Tina E , Lynch Heather , Fisch Verena K
Published: May 2022

This article contributes a comparative review of social work in Canada and Scotland to international conversations about social work and the environment. The ‘environmental question’ of the 21st century is a radical challenge to social work developed in relation to the ‘social question’ of the 19th century. Work to begin to include the natural environment within high-income state social work can expect to encounter established infrastructures of thinking and doing that will be difficult to shift. We, therefore, compare guiding social work policy documents and identify points of tension that are likely to be shared across wealthy national contexts.
Feminisms in social work and social care: Backwards, forwards or something in between
Authors: Fawcett Barbara
Published: May 2022

The various feminisms create a complex and sometimes contradictory picture. Within social work and social care, there has been a mixed reception. However, it is maintained that a gendered analysis in a profession where women remain in the majority remains highly relevant. In particular, the continuing and increasing pay gap and the relatively low numbers of women in senior positions are used as markers. Similarly, comparisons between ‘choice’ feminism and current practices are appraised. It is argued that critical deconstructive analyses drawn from postmodern feminism remain significant in both naming and addressing pervasive gender inequalities in national and international arenas.
Impairing Social Connectedness: The Dangers of Treating Grief With Naltrexone
Authors: Thieleman Kara , Cacciatore Joanne , Thomas Shanéa
Published: May 2022

A study is currently underway in the United States using the opioid antagonist naltrexone to treat prolonged grief, which is conceptualized in the study’s proposal as an addiction disorder. The researchers’ stated intention is to use the pharmaceutical agent to disrupt the griever’s capacity to engage in social bonding to eliminate craving for the person who died. We believe this approach is misguided for a number of reasons. It demeans the importance of the relationship between the bereaved and the deceased loved one, further isolates grievers from the very social support networks that could help facilitate adaptation to bereavement, and could have a disproportionate negative impact on marginalized communities, who tend to rely more heavily on informal sources of support. We argue that social connection is at the very core of healing and that disregarding and interfering with this capacity could have widespread detrimental effects on grievers.
Collective regulation and the future of work in the digital economy: Insights from comparative employment relations
Authors: Doellgast Virginia , Wagner Ines
Published: May 2022

The impact of technological change on employment, inequality and job quality has attracted considerable analysis from both scholars and practitioners. However, less attention has been paid to how digital technologies are changing contemporary workplaces and how workers are responding to these changes. This article reviews recent research from the multidisciplinary comparative employment relations field, with a focus on institutional resilience or change associated with digitalization; and the strategic responses of unions and other worker representatives to these trends. We find that the insights of economists, sociologists and employment relations scholars are complementary, as each addresses a different dimension of technological change and associated worker outcomes. Comparative employment relations researchers are more likely to influence current debates where they both articulate the unique contribution of their multi-method and comparative research methods and aggregate findings beyond single or paired industry and national case studies.
Current state of cause of death determinations in Japan and the need to list the precise underlying cause of death
Authors: Inoue Ken , Abe Shuntaro , Fukunaga Tatsushige
Published: May 2022

When death is caused by a disease, the precise cause of the death must be determined to promote health and contribute to prevention efforts. The circumstances of death should also be clarified so that measures can be taken to prevent the recurrence. Statistics regarding the cause of death must be accurate, and such statistics are shaped by the determination of the cause of death. We examined the annual cause of death rankings and the mortality rate in Japan during the 25-year period 1993–2017. We identified improvements that are needed to provide more precision in the cause of death statistics, with a focus on variations in the rankings, and we describe the peculiar and vulnerable aspects of the Vital Statistics system in Japan; for example, at one time the national government advised physicians to not list “heart failure” as the terminal stage of a condition on a death certificate, and the “heart disease” mortality rate thus tended to decline in that period. The ranking of “heart disease” as a cause of death decreased, but its mortality rate subsequently increased again. In addition, the “pneumonia” mortality rate has remained high over the past few years, but it abruptly decreased in 2017, when “aspiration pneumonia” was separated as a cause from other pneumonias. The “senility” mortality rate has increased annually, and it is a leading cause of death. It is important that physicians understand the underlying causes of death and provide that without being influenced by the reporting customs of the times.
Animals for the mayor: Barcelona’s zoo in the making of local policies and national narratives (1957–73)
Authors: Carandell Baruzzi Miquel
Published: May 2022

From 1957 to 1973, Barcelona Zoo was transformed from a small-scale, antiquated establishment harboring very few animals, a place that was still in a poor condition following the Spanish Civil War, into a new, larger, modern, and internationally recognized institution that included up-to-date animal enclosures and that boasted one of the first dolphinariums in Europe, as well as a famous white gorilla as its icon. From its very beginning, this renovation involved an intense popularization campaign.

In this paper, by describing the public discourse generated throughout this transformation and by analyzing the roles played by Antoni Jonch, the director of the zoo at that time; Josep Maria de Porcioles, the then-mayor of Barcelona; and General Francisco Franco, the Spanish dictator who was head of state during this period, I will highlight how the context of the dictatorship not only authorized the new Barcelona Zoo but is, in fact, crucial to its understanding. The narratives that surrounded the renovation of the zoo focused on its civic and educational purpose, with a firm emphasis on modernity. The zoo was a modern space for learning about animals in order to become better people. These narratives were not only suitable to the policies, ideas, and aims of Porcioles’ City Council and Franco’s dictatorial regime; in fact, they completely matched them. Both local and national governments benefited from the restructuring of Barcelona Zoo and from its public discourse as a tool for social control and an instrument for their own propaganda, legitimation, and perpetuation.
Effect of pre-axial tensile tension, temperature, and hysteresis loss of natural rubber doped MWCNTs on the electrical properties for sensors applications
Authors: Aljuraide NI , Abd Elbary AM , Tammam MT
Published: May 2022

In view of its large application, one used natural rubber (NR). The effects of MWCNTs contents on electrical properties as well as the effect of both pre extension and mechanical hysteresis on the electrical properties of these composites were discussed. At low MWCNTs contents (≤6 phr), έ, σac, and σdc showed to have slight changes. Meanwhile, contents (≥9 phr) have significant increase as a result of its interfacial polarization. That is, the composite became conductive. Higher positive electrical conductivity coefficient (PTCC) intensity was detected for the 3phr sample. The effect of the electric field on the mechanical creep characteristics and its corresponding parameters were investigated. Conventional elastic modulus was found to increase with both MWCNTs concentration and the applied stress in all samples about six times its original value. Current creep curves were constructed and maximum piezoresistivity was found for sample 3phr with a negative effect on piezoresistivity, which can be employed as a pressure or force sensor. The parameters deduced from hysteresis loop such as the strain coefficient of conductivity, damage parameter, strain energy density, inelastic strain, elastic strain, and mismatch parameter are strongly dependent on both the MWCNTs concentration and the applied mechanical stress. The damage parameter increased to about 20 times with increasing the concentration, while the decreases with increasing number of hysteresis cycles. The activation energy decreased with the pre-axial tension, while no effect of electrical conductivity.
Joint probability distribution of air temperature and global solar radiation for outdoor design conditions based on copula approach
Authors: Jiao Zhichao , Emura Kazuo
Published: May 2022

In the common method of compiling outdoor design conditions by annual cumulative frequency of occurrence, the probability of simultaneous occurrence of the selected meteorological elements is not considered, which may lead to an overestimation of air-conditioning equipment capacity design. This paper aims at developing a novel approach for producing the outdoor design conditions, taking into consideration the dependency between the air temperature and global solar radiation, which have a strong influence on the HVAC capacity design. These two meteorological elements are analyzed for specific simultaneous occurrence probability based on the joint distribution. For this purpose, the copula approach which can describe the dependence between these two meteorological elements is used for modeling the joint distribution function. We investigated copula family selection for air temperature and global solar radiation at each hour of hourly weather data for 10 years from 2001 to 2010 in Osaka, Japan. The Joe-Frank copula has the best fitting results for the dependence between the air temperature and global solar radiation. According to the comparison of original exceeding probability and simultaneous occurrence probability, the results show that the design conditions based on the common method can significantly exceed that of the simultaneous occurrence probability method.

Practical Application: Outdoor design conditions are used in the building design stage to estimate building performance and select the appropriate air conditioning equipment capacity. Excessive air-conditioning capacity may lead to a large amount of unnecessary energy wastage. Insufficient capacity may lead to not meeting the desired indoor environment conditions of utilization in extreme weather conditions, especially for large office buildings. Therefore, this paper provides a new approach to generate more realistic meteorological conditions for air-conditioning design to improve building energy efficiency.
Reclaiming the human in machine cultures: Introduction
Authors: Natale Simone , Guzman Andrea L
Published: May 2022

The relationship between technology and culture has always been a contested issue in media and cultural studies. Ongoing advances in computing and Artificial Intelligence (AI), however, are posing new kinds of questions and challenges to the field. As many have argued, these technologies invite to rethink the relationship between technology and culture, positing the idea that not only humans, but also machines produce and construct ‘culture’. The goal of this themed issue is to consider notions such as ‘algorithmic culture’ and ‘machine culture’ from within the tradition of media and cultural studies, in order to move toward a conceptualization of culture in which machines are intertwined within human systems of meaning-making. In this introduction to the themed issue, we discuss why these emerging technologies and the human cultures forming around them are integral to the mission of media and cultural studies, and what the media and cultural studies tradition can bring into ongoing and future debates regarding the nexus of humans, machines, and culture.
“Riverboat Ron”: A Critical Reading of Ron Rivera, American Brownness & Latino Masculinities in the NFL
Authors: Moraga Jorge E.
Published: May 2022

Ron Rivera, after eight and a half years as the only Latino Head Coach employed by the NFL, was fired in 2019 by Carolina Panthers’ new ownership. Soon after, Rivera was hired as the new Head Coach of the then-Washington Reds*ins. Empowered to not only coach the team, he has been tasked to shake up the organization's cultural, gendered, and racialized leadership-status-quo. In doing so Coach Rivera threads new ground across the ever evolving color line in U.S. sports, particularly “the brown color line.” This essay explores the life, career, and ongoing-regionally based celebrity stardom of Ronald Eugene Rivera. I argue that Ron Rivera charts pathways forward amidst a U.S. socio-cultural-political climate rooted in anti-Native, anti-Black, anti-immigrant sentiment and a sporting industry embezzled in neoliberal racial politics. The essay theorizes “brownness” in sport from a “Latino masculinity” perspective to situate Rivera's struggles for (in)/(hyper)visibility and the complexed realities of the ongoing gendered color line in U.S. sport amid social pressure and protests for transformation and change.
Mind, body, and soul: The effects of bodily movement on listeners’ perceptions of choral performances
Authors: Langley David W
Published: May 2022

The purpose of this study was to examine what effect performer’s bodily movement may have on listeners’ (N = 103) perceptions of a choral ensemble performance. A 34-voice choir was audio/video recorded performing two different musical excerpts. Each excerpt was recorded twice, once with movement and once without movement, for a total of four audio/video recordings. Additionally, the audio from each of these recordings was isolated and used as a separate stimuli. Participants were presented each stimuli (movement/non-movement, audio only/audio + video), and asked to rate each for expressivity and style. The factor of audio/video was not found to have consistently significant differences in rating. However, there was a consistent interaction effect between these two stimuli, suggesting that both the visual and auditory differences when using movement conversely effected the listeners’ perception. College major did not prove to be a consistent indicator, but membership in a choral ensemble significantly impacted ratings. Implications may include a greater effect of movement when viewed by the listener than simply what can be perceived in the aural stimuli alone. Suggestions for further research include additional study between choral and instrumental music.

Nostalgia and political analysis: A perspective from the Israeli case
Authors: Yadgar Yaacov
Published: May 2022

I argue here for the relevance and importance of the study of nostalgia for political analysis. Focusing on the case of Israel, I propose that a study of nostalgia can yield, at least in the case at hand, insightful views of political reality that other approaches to the study of politics may fail to expose. Specifically, I focus on a nostalgia prevalent among the dominant Ashkenazi ethno-class, accompanied by a Mizrahi ‘counter’ nostalgia. I argue that these nostalgias tell us volumes – like other nostalgias can do – about the ways people and their socio-political groups understand their world and their place within it in the present and formulate their hopes for the future. In this, nostalgia proves to be an important part of the toolkit of the study of politics, alongside the study of political myth and symbols.
Prolonged disorders of consciousness: A response to a “critical evaluation of the new UK guidelines.”
Authors: Wade Derick T , Turner-Stokes Lynne , Playford E Diane , Allanson Judith , Pickard John
Published: May 2022

Background

In 2020, The London Royal College of Physicians published “Prolonged disorders of consciousness following sudden-onset brain injury: national clinical guidelines”. In 2021, in the journal Brain, Scolding et al. published “a critical evaluation of the new UK guidelines”. This evaluation focussed on one of the 73 recommendations in the National Clinical Guidelines. They also alleged that the guidelines were unethical.

Criticisms

They criticised our recommendation not to use activation protocols using fMRI, electroencephalography, or Positron Emission Tomography. They claim these tests can (a) detect ‘covert consciousness’, (b) add predictive value and (c) should be part of routine clinical care. They also suggest that our guideline was driven by cost considerations, leading to clinicians deciding to withdraw treatment at 72 h.

Evidence

Our detailed review of the evidence confirms the American Academy of Neurology Practise Guideline (2018) and the European Academy of Neurology Guideline (2020), which agree that insufficient evidence supports their approach.

Ethics

The ethical objections are based on unwarranted assumptions. Our guideline does not make any recommendations about management until at least four weeks have passed. We explicitly recommend that expert assessors undertake ongoing surveillance and monitoring; we do not suggest that patients be abandoned. Our recommendation will increase the cost We had ethicists in the working party.

Conclusion

We conclude the “critical evaluation” fails to provide evidence for their criticism and that the ethical objections arise from incorrect assumptions and unsupported interpretations of evidence and our guideline. The 2020 UK national guidelines remain valid.
Evaluating and understanding combination therapy decision drivers for the treatment of overactive bladder in the United States
Authors: Kraus Stephen R. , Li Junlong , Kristy Rita M. , Lockefeer Amy , Yang Hongbo , Zhou Mo , Walker David R.
Published: May 2022

Objective

To understand factors guiding overactive bladder (OAB) therapy selection and experience with combination therapy (antimuscarinics and beta-3 agonists).

Methods

Cross-sectional surveys of OAB patients and OAB-treating physicians in the USA were conducted. Patients receiving monotherapy with antimuscarinics were categorized by OAB treatment history: monotherapy only; third-line procedures (e.g., onabotulinumtoxinA injections) and combination therapy; third-line therapy only; and combination therapy only. The patient survey assessed therapy choice drivers and barriers, treatment satisfaction and sociodemographic/clinical characteristics. The physician survey assessed drivers of and barriers to OAB treatment choices.

Results

Of 200 patients, 86.5% reported involvement in treatment decision-making; doctor’s recommendation was the most frequently considered factor (84.4%). Most patients (71%) were unaware of combination therapy. The primary reason why those patients aware of combination therapy had not used it (N = 43/200; 21%) was physician recommendation of other treatments (69.8%). For physicians (N = 50), the most frequently considered factors when prescribing OAB treatment were effectiveness (92.0%) and side effects (84.0%); 70% prescribed combination therapy, primarily for symptom severity (82.9%). The main reasons for not prescribing combination therapy were cost/insurance coverage (80%) and lack of information (53.3%).

Conclusions

Shared decision-making guided treatment decisions; the main considerations were treatment safety and efficacy.
Desires, Fantasies and Hierarchies: Postcolonial Status Anxiety through Ontological Security
Authors: Bilgic Ali , Pilcher Jordan
Published: May 2022

Status-seeking practices of some states from the Global South have increasingly been studied in the status literature in International Relations. The existing debates, whilst developing significant advances recently, still fail to account for and theorise both status anxieties of postcolonial states and the intrinsic relation between them and existential anxieties. This article will address this gap through utilising an ontological security perspective on status-seeking. By focusing on subjectivities (not solely on identities as conventionally done in the status literature) and introducing subject production to the process of status-seeking, this article conceptualises status in relation to identity narratives of the subject to achieve ‘wholeness’ in hierarchical social orders. This novel post-structuralist understanding of status and status-seeking through the introduction of a Lacanian theorisation of ontological security offers an alternative perspective to approaches in status debates to understand status anxieties of postcolonial states better. The conceptual discussion will be illustrated through demonstrating Turkey’s status anxiety in relation to its paid-off debt to International Monetary Fund.
Exploring potential for occupational therapy practice models within areas of social deprivation: A qualitative inquiry within a community-centred food cooperative
Authors: Adams Richard , Atkin Helen , Lee Richard , Hackett Simon S , Hackett Katie L
Published: May 2022

Background

A health inequalities gap exists between wealthy and deprived areas. Community-level occupation-focused interventions may support citizens and address inequities within their environments. Since the global financial crash of 2008 and fiscal policy changes within the United Kingdom, there has been a rise in food insecurity. Community volunteer initiatives have responded by providing for their residents. The aim of this study was to explore how occupational therapists may be agents for social change through exploring perspectives of members and volunteers from a community food cooperative in an area of social deprivation.

Methods

Eight semi-structured interviews were conducted with cooperative members and volunteers within a food cooperative established to address food insecurity in a local community. Data were analysed using thematic analysis.

Results

We found three main themes: It’s Not a Foodbank, Shared Hardship and a cross-cutting theme of Community. The results suggest occupation-focused responses can support the development of community and collective occupations thereby contributing solutions to shared problems.

Conclusion

A community-centred, rights-based approach has supported local community need where socio-economic disadvantage and health inequalities were identified. Scope exists for occupational therapists to work genuinely with (not for) communities to address occupational injustice through collective occupation.
Disinformation and Echo Chambers: How Disinformation Circulates on Social Media Through Identity-Driven Controversies
Authors: Diaz Ruiz Carlos , Nilsson Tomas
Published: May 2022

This article investigates how disinformation circulates on social media as adversarial narratives embedded in identity-driven controversies. Empirically, the article reports on the flat Earth echo chamber on YouTube, a controversial group arguing that the earth is a plane, not a sphere. By analyzing how they weave their arguments, this study demonstrates that disinformation circulates through identity-based grievances. As grudges intensify, back-and-forth argumentation becomes a form of knowing that solidifies viewpoints. Moreover, the argument resists fact-checking because it stokes the contradictions of identity work through grievances (pathos) and group identification (ethos). The conceptual contribution proposes a two-phase framework for how disinformation circulates on social media. The first phase, “seeding,” is when malicious actors strategically insert deceptions by masquerading their legitimacy (e.g., fake news). The second phase, “echoing,” enlists participants to cocreate the contentious narratives that disseminate disinformation. A definition of disinformation is proposed: Disinformation is an adversarial campaign that weaponizes multiple rhetorical strategies and forms of knowing—including not only falsehoods but also truths, half-truths, and value-laden judgments—to exploit and amplify identity-driven controversies. Finally, the paper has implications for policy makers in handling the spread of disinformation on social media.
Attitudes of Palliative Care Practitioners Towards Enrolling Patients in Clinical Trials
Authors: Nagla Ahmed , Le Brian , White Clare , V Kiburg Katerina , Philip Jennifer
Published: May 2022

Background: Recruitment of participants for clinical trials remains a key consideration for investigators. This is particularly relevant in palliative care, where practitioners are sometimes reluctant to refer patients for consideration of enrolment. Reasons for this reluctance range from concerns about excessive burden to patients, through to debate about the appropriateness of undertaking trials in the palliative care setting. Aim: The aim of this study was (1) to explore palliative care practitioners’ attitudes and views of clinical trials, (2) to compare these findings with those of a similar survey undertaken more than a decade earlier, and (3) to explore predictors associated with key concepts of interest associated with clinical trials. Design: The palliative care clinician's attitudes to clinical research survey undertaken in 2007 formed the basis of a repeat survey conducted in 2019. Setting/Participants: Australian and New Zealand palliative care practitioners were surveyed. Results: Surveys were completed by 135 palliative care practitioners. Comparing results of the current study and those findings of more than a decade earlier revealed that attitudes have either not substantially changed or indeed in some areas have become less accepting of clinical trials. This is despite the dramatic increase in the volume of research carried out within palliative care over the last decade. Conclusion: Our survey suggests that the reasons for engagement in research are complex and likely to differ according to local conditions. Careful attention to understanding of the local environment and particularly the attitudes of local practitioners is likely to be essential to be successful in this endeavour.
Gender Typicality and Prestige of Occupational Aspirations in Adolescents: The Relevance of Agency and Communion
Authors: Korlat Selma , Schultes Marie-Therese , Schober Barbara , Spiel Christiane , Kollmayer Marlene
Published: May 2022

Occupational gender segregation is still a persistent problem in the labor market. This study investigates gender differences in gender typicality and prestige of occupational aspirations in early adolescence, as well as the role of agency and communion in these differences. In total, 2779 adolescents (age 11–15) reported their occupational aspirations, later coded for gender typicality and prestige. Participants also described themselves spontaneously with three attributes, then coded in terms of agency and communion. The results showed significant gender differences in a stereotypical direction for 40% of the occupations named, with boys expressing a clear preference for male-dominated and girls for female-dominated occupations. Conversely, the results revealed higher aspirations among girls regarding occupational prestige. Communion was found to be a significant mediator between gender and aspirations to typically feminine occupations, while agency mediated the relationship between gender and the prestige of aspirations. The findings’ implications for theory and practice are discussed.
Analytically predicting the burst pressure of composite rupture discs by considering nonlinear strain path
Authors: Mohebbi Morteza , Panahizadeh Valiollah , Hoseinpour Mohammad
Published: May 2022

The composite rupture discs are a safety device that burst at the specified pressure and prevent overpressure and damage to equipment by releasing the fluid at high flow rates. The burst pressure is determined by the bulge formed and then slotted sheet metal. In the hydraulic bulge-forming stage, the sheet is subject to biaxial stress, and after slotting, it is subject to uniaxial tensile stress. Due to the change in the loading type, the sheet has a nonlinear strain path during the bulge-forming and burst test after slotting. In the nonlinear strain paths, the equivalent failure strain changes according to the strain path. In this paper, based on the FEM simulation results and experimental tests, the relationship between plastic failure strain in uniaxial tensile state and the maximum pre-strain due to bulge forming is investigated. According to the results of this paper, when the sheet sufficiently forms under hydraulic pressure, the maximum strain in hydraulic bulge-forming and the equivalent failure strain after slotting are equal. Based on this result, analytical relations were developed to predict the burst pressure of composite rupture discs. This relation estimates the burst pressure of composite rupture discs with an average error of about 13%.
Accurate evaluation on residual stress considering solid-state phase transformation and initial stress in thick weld
Authors: Zhang Qingya , Wang Jiangchao
Published: May 2022

During the welding process of thick plates, it is difficult to evaluate the residual stress distribution in thick welds accurately because complicated residual stress is generated by multi-thermal cycles. In this study, a multi-pass butt joint was fabricated using Q690 high strength steel with the thickness of 75 mm, meanwhile experiments were carried out to characterize the microstructure and measure the through-thickness distribution of longitudinal residual stress in a butt-welded joint by the contour method. Then numerical methods were developed to predict the through-thickness distribution of residual stress in butt-welded joints. To evaluate residual stress accurately and efficiently, the effects of solid-state phase transformation (SSPT) and initial stress were taken into consideration, and the parallel computation technology and iterative substructure method were employed. The root-mean-square error (RMSE) was employed to evaluated the prediction accuracy of numerical methods between measurement and numerical results of residual stress. Through comparing the simulated results with experimental data, the validity of the developed numerical methods was verified. Numerical results indicate that the through-thickness distribution of residual stress in butt-welded joints is very complex and peak value of tensile stress can be found in the area adjacent to the heat-affected zone (HAZ). Moreover, the RMSE is significantly decreased from 307 to 8 when considering the effect of SSPT on residual stress in weld vicinity, and the RMSE is apparently decreased from 137 to 11 when considering the effect of initial stress on residual stress in base metal.
Characterization of adhesive curing reactions using rapid heat rheology
Authors: Glaser Sarah , Zarmandili Omid , Stammen Elisabeth , Dilger Klaus
Published: May 2022

Understanding the curing mechanisms of adhesives presents basic knowledge of planning adhesive application and bonding processes. The demand for short manufacturing cycle times drives the development of rapid curing adhesives. Furthermore, the processing parameters influence both: the process time and the adhesive properties. This motivates upgrading the boundary conditions of common rheometric measurement methodologies to reflect application process parameters. For this purpose, it is imperative to investigate the interaction of fast-curing adhesive, rheometric method and measuring device setup. Influences on the measurement accuracy caused by highly dynamic heating processes must be minimized or compensated for in the evaluation of the results. At the same time, knowledge must be acquired on how to determine the material-specific process limits. The resulting systematics for the development of fast-curing adhesives and for the planning of adhesive manufacturing processes will enable a significant industrial spread of fast curing with all its advantages. This paper provides a first step in this process by investigating the curing behavior of a thermal rapid curing one component polyurethane adhesive at heating rates of 50 and 100  K/min. The results for the evolution of the shear modulus are compared to the results from standard rheometric methods.
An experimental study on abnormal vibration of metro trains caused by out-of-round wheels
Authors: Wang Jintian , Ding Xin , Liu Zhendong , Teng Wanxiu , Liu Tao , Li Yongsheng
Published: May 2022

Out-of-round (OOR) wheel often happens to trains, which can cause abnormal vibration. To develop effective countermeasures to minimize the abnormal vibration, it is necessary to study how the wheel OOR wear affects the vehicle vibration. This paper performs an experimental study on the abnormal vibration characteristics of metro trains with out-of-round wheels. The vibration characteristics is identified by the general survey of wheel roughness from special tests. The statistic wheel wear values of all the vehicles in an operating metro lines are studied to investigate the relationship between the wheel wear and the operating mileage. Several re-profiling strategies are implemented to eliminate the abnormal vibration caused by wheel OOR. The results show that the root cause of the abnormal vibration and deterioration of ride comfort is the car-body flexible resonance excited by the wheel OOR wear. Wheel re-profiling is the most effective measure for reducing the vehicle abnormal vibration. By re-profiling all the wheels of a tested metro vehicle, the ride comfort can be improved by 35% ∼ 40% and the axle-box acceleration can be reduced by 40%.
Foreign medical graduates and American psychiatry
Authors: Hirshbein Laura
Published: May 2022

Graduates from foreign medical schools (FMGs) began to staff US state psychiatric hospitals after World War II, and became increasingly associated with the poor quality of those institutions. Public and professional commentary on FMGs criticized their skills and suitability for the US healthcare system in the 1970s, at the same time that state hospitals were under increasing attack. By the 1980s and 1990s, the association between international medical graduates (as they became known) and underserved populations became an argument in favour of easing restrictions on these graduates. The role of foreign-trained psychiatrists in the US public sector became a way for American psychiatry leaders to manage the problems of the seriously mentally ill, first with blame and then with neglect.
Vibration control of laminated composite cantilever beam operating in elevated thermal environments using fuzzy logic controller
Authors: Akumalla Ravi Kiran , Kallannavar Vinayak , Kattimani Subhaschandra
Published: May 2022

In the present study, vibration control of laminated composite cantilever beam operating in the elevated thermal environment is achieved using combined experimental and numerical techniques. The impact hammer test is performed on the glass-epoxy cantilever beam at different temperatures. Experimentally recorded impact hammer force signals and piezoelectric accelerometer time-domain signals are processed through a system identification toolbox in MATLAB to obtain transfer functions of the plant models. A robust fuzzy logic controller is developed to accomplish the effective vibration control of a cantilever composite beam operating at different temperatures. The fuzzy logic controller with two inputs and one output is designed using the 20 if-then rules. The results are presented in both frequency and time domain, keeping the vibration attenuation of the fundamental frequency as the point of interest. The results indicate the proposed fuzzy logic control strategy can attenuate the vibrations of a cantilever composite beam for a wide temperature range.
Variance partitioning in spatio-temporal disease mapping models
Authors: Franco-Villoria Maria , Ventrucci Massimo , Rue Håvard
Published: May 2022

Bayesian disease mapping, yet if undeniably useful to describe variation in risk over time and space, comes with the hurdle of prior elicitation on hard-to-interpret random effect precision parameters. We introduce a reparametrized version of the popular spatio-temporal interaction models, based on Kronecker product intrinsic Gaussian Markov random fields, that we name the variance partitioning model. The variance partitioning model includes a mixing parameter that balances the contribution of the main and interaction effects to the total (generalized) variance and enhances interpretability. The use of a penalized complexity prior on the mixing parameter aids in coding prior information in an intuitive way. We illustrate the advantages of the variance partitioning model using two case studies.

Background:

GV20 and Yintang are important targets in acupuncture treatment for depression. In this study, we examined the antidepressant effects of simultaneous acupuncture stimulation at GV20 and Yintang.

Methods:

We compared the antidepressant effects of manual acupuncture (MA) stimulation at GV20 and Yintang, compared to acupuncture stimulation at two control point locations on the back of the mice (overlying the spinal column) and imipramine administration in a forced swimming (FS)-induced mouse model of depression, and examined the mRNA and protein expression of neurotrophic factors, including nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin (NT)-3, and NT-4/5 in the brains by real-time polymerase chain reaction in two different experimental schedules – preventive (MA given alongside FS modelling) and therapeutic (MA given after FS-induced depression was already established).

Results:

MA at GV20 and Yintang significantly reduced the immobility time of mice with FS-induced depression in both preventive and therapeutic experimental designs, with effects that were comparable to those of imipramine administration. Immobility time following simultaneous acupuncture stimulation of the two control point locations overlying the spinal column was significantly suppressed only 2 weeks after the start of FS in the preventive effect experiment, and the suppressive effect was significantly lower than that of simultaneous acupuncture stimulation at GV20 and Yintang. In the therapeutic effect experiment, there was no change in the increase in immobility time after the end of FS. MA at GV20 and Yintang significantly increased the expression of BDNF and NT-3 in the preventive evaluation and NGF, BDNF, NT-3, and NT-4/5 in the therapeutic effect evaluation.

Conclusion:

Our findings suggest that simultaneous acupuncture stimulation at GV20 and Yintang is effective for the prevention and treatment of depression, and the effect likely involves modulation of the expression of multiple neurotrophic factors.
Street Mothers: How Might a Feminist Critique of Christology Impact the Christian Faith of Women on Council Estates in the United Kingdom?
Authors: Cowan Sophie
Published: May 2022

This article engages feminist critiques of Christology with the views of Christian women living on council estates in the United Kingdom. It explores some of the ways in which the faith of such women connects with and/or contradicts feminist and womanist understandings of Christ. It is demonstrated that Jesus has been thought of in terms of ‘Nan-Nan’, or as a ‘Street Mother’, and that women living in areas of economic deprivation, and elsewhere, might lay claim to such terminology as a way to further articulate identification with Christ, and in order to challenge traditionally androcentric Christology. A series of Christological questions are explored, for example, ‘Who is Jesus?’; ‘Do you think Jesus puts men in charge of women?’ and the anonymised answers are recorded at the beginning of each chapter. It is proposed that feminist Christology may enhance a sentiment already present among Christian women on estates, and, further to this, propel the pursuit of liberation from kyriarchal oppression. In this way, the Christian faith of women on estates is, and can become more and more so, an act of insubordination in the face of oppression of many kinds. Not least, it contributes a fresh and important Christological perspective.
Conceptual framework for the ethical climate in health professionals

Published: May 2022

The ethical climate is the perception of health professionals about the work environment, meaning the reflection on care practices and ethical-related decisions. There are extensive studies in the international literature about the ethical climate, but there are still theoretical gaps about it in health services. In this reflection article, the objective was to explore conceptual components about the ethical climate, proposing new elements of analysis of the construct. The starting point was the accumulated knowledge itself, the possibilities for expansion, and the conceptual progress emerging from contributions from studies on nursing ethics. It was understandable that the ethical climate is considered in its procedural model and cyclically, being articulated with organizational elements, as established in the literature, and, expanding the concept, with the worker’s health and the ethical expressiveness at work. Regarding this last contribution, the suggestion is to think about the potential for work to allow, limit, or favor professionals to express their ethical and esthetic values in the most daily decisions and relationships, in care, management, and education. The conceptual framework of this study progressed by addressing the ethical climate as a process articulating several concepts and elements regarding the organizational aspect, ethics, and the workers’ well-being.
Culturally Responsive Leadership for Latinx Immigrant Students: Advocacy in a U.S.–Mexico Border Alternative School
Authors: Crawford Emily R. , Aguayo David , Valle Fernando
Published: May 2022

Educators on the U.S.–Mexico border work with students’ intricate lived experiences while striving to provide them with an equitable education. For Latinx immigrant students, school discipline is a significant component of the broader educational experience. Nonconformity to US schooling norms and policies may lead to students being sent to alternative schools. In this paper, we explore how educators in an alternative school in Texas on the U.S.–Mexico border enacted advocacy for students. Our research questions ask (1) what relationships or traits facilitate or constrain leaders’ advocacy to assist Latinx immigrant students in obtaining a quality education? and (2) what policies and structures facilitate or constrain leaders’ advocacy to assist Latinx immigrant students in obtaining a quality education? Research for this paper comes from an embedded case study, focusing on one principal and six other educators in one K-12 borderland alternative school in Texas. Culturally responsive school leadership (CRSL) practice frames the work conceptually. Study results reveal the principal and her staff experienced challenges but worked within the realities of the border, utilized critical discretion and courage in response to policy, and strengthened family and community relationships to reduce social and educational barriers for transnational students and families. The study demonstrates that increased professional responsibility among all organizational members is key for the safety, well-being, and inclusion of all students. Schools must develop individual capacity to participate in leadership processes to confront the numerous challenges that limit immigrant students’ equal educational access.
