Can Dance and Music Make the Transition to a Sustainable Society More Feasible?

Transition to sustainability is a process that requires change on all levels of society from the physical to the psychological. This review takes an interdisciplinary view of the landscapes of research that contribute to the development of pro-social behaviors that align with sustainability goals, or what we call ‘inner sustainability’. Engaging in musical and dance activities can make people feel trust and connectedness, promote prosocial behavior within a group, and also reduce prejudices between groups. Sustained engagement in these art forms brings change in a matter of seconds (such as hormonal changes and associated stress relief), months (such as improved emotional wellbeing and learning outcomes), and decades (such as structural changes to the brains of musicians and dancers and superior skills in expressing and understanding emotion). In this review, we bridge the often-separate domains of the arts and sciences by presenting evidence that suggests music and dance promote self-awareness, learning, care for others and wellbeing at individual and group levels. In doing so, we argue that artistic practices have a key role to play in leading the transformations necessary for a sustainable society. We require a movement of action that provides dance and music within a constructive framework for stimulating social sustainability.

Effect of thermal cycling on mechanical and microstructural properties of heat-treated Ti-6Al-4V alloy

Titanium (Ti-6Al-4V) is an α+β phase-field alloy utilized in many industries due to its high strength-to-weight ratio and near-net shaping capability. Solution treated & aging, and stress relief annealing processes were performed on the samples to increase the strength and % of elongation. The heat-treated samples then thermally cycled for 500 cycles, 1000 cycles, and 1500 cycles to evaluate the microhardness and tensile properties. The presence of martensite and α2 precipitates in the thermally cycled samples was confirmed by scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD). In this investigation, at 1000 thermal cycles, all specimens show improvement in both hardness and strength when compared within the cycles. Solution-treated and aging (STA), stress relief annealing (SRA), and without any heat-treatment (WHT) processes have their highest hardness values recorded for 1000 thermal cycles, and the values are 471 HV0.5, 381 HV0.5, and 374.6HV0.5, respectively. For the SRA process, ultimate tensile strength (UTS) of 925 MPa and yield strength (YS) of 896 MPa have resulted in 1000 cycles. Similarly, at 1000 thermal cycle WHT processed samples yielded UTS of 920 MPa and YS of 885 MPa. STA process samples that are heat-treated for 1000 thermal cycles have better strength properties than SRA and WHT and had a UTS of 1530MPa and YS of 1420MPa. From a ductility point of view, a maximum elongation of 29% for the STA process has resulted. Compared to forged titanium alloy (base metal), an increase of 31% elongation and 41% ultimate tensile strength for solution treated and aging process at 1000 cycles has resulted in this investigation.

What Really Matters: The Effect of Covid-19 on the Factors of Life Satisfaction

This article investigates the effect of the Covid-19 pandemic on the structure of factors of life satisfaction in the city of Usti nad Labem, Czech Republic. The dataset is based on a questionnaire survey conducted in Usti nad Labem, Czech Republic. Subsequent data analysis is conducted using ordinal logistic regression models. The results show that the emergence of the pandemic had a significant impact on life satisfaction factors. Firstly, the importance of family came to the fore: being in a relationship or being married proved to be a significant factor of life satisfaction during the pandemic but not before the pandemic. Secondly, a negative association between drinking alcohol and life satisfaction emerged during the pandemic. Alcohol probably started to be the tool for stress relief. Thirdly, sport became a significant positive factor of women’s life satisfaction. Sport most likely became an effective way of keeping oneself in balance. Results indicate that during a difficult time period there are different ways of how to deal with it. In this way doing sports and drinking alcohol seem to be substitute activities.

Effects of the Vibration Amplitude in Vibratory Stress Relief on the Fatigue Life of Structures

This research aims to investigate the effects of vibration amplitude in vibratory stress relief (VSR) on the fatigue strength of structures with residual stress. Experiments are carried out on specimens with residual stress generated by local heating. Flat specimens made of A36 steel are prepared to be suitable for setting up fatigue bending tests on a vibrating table. Several groups of samples are subjected to VSR at resonant frequencies with different acceleration amplitudes. The results show that VSR has an important influence on the residual stress and fatigue limit of steel specimens. The maximum residual stress in the samples is reduced about 73% when the amplitude of vibration acceleration is 57 m/s2. The VSR method can also improve the fatigue limit by up to 14% for steel samples with residual stress.

The Effects of Soundscapes in Relieving Stress in an Urban Park

Urban parks are important urban public spaces that guarantee people recreation, create positive emotions and relieve stress. Emerging research has shown that natural soundscapes are associated with restorative landscapes in urban parks. However, there is still a lack of knowledge on the use of physiological indexes to evaluate the effects of natural sounds versus human-based sounds on stress relief. In this study, the three physiological indexes of skin conductance level, heart rate and heart rate variability were collected in Fuzhou West Lake Park with the help of Ergo LAB data platform, and a soundscape perception evaluation questionnaire was used to assess the degree of soundscape perceptions in the sample sites. The differences in the stress relieving effects of different urban park environments were analysed by applying the median test, the Wilcoxon test was applied to analyse the effects of soundscapes and urban park environments on relieving stress, and regression analysis was used to identify the important factors of restorative soundscapes. The results found that urban park environments provide a certain degree of stress relief, but the stress relieving effects of different urban park environments vary and that natural spaces play an important role in relieving stress. Urban park soundscapes are key to restorative environmental design, with natural sounds such as birdsong and stream sound being important factors of restorative soundscapes.

The Effects of Leisure Life Satisfaction on Subjective Wellbeing under the COVID-19 Pandemic: The Mediating Role of Stress Relief

Under the continuous spread of COVID-19 infection, individuals are finding their own ways to manage their stress and subjective wellbeing. The main objective of this research is to test the role of leisure life satisfaction on one’s subjective wellbeing in the era of COVID-19 as mediated by stress relief. Individuals’ satisfaction with leisure life is hypothesized to both directly and indirectly affect their subjective wellbeing as mediated by relieved stress. The positive impact of stress relief on one’s subjective wellbeing is hypothesized to be moderated by the perceived seriousness of the COVID-19 pandemic. Data from a large-scale social survey in South Korea (N = 40,085) were used to test the hypotheses and the results confirmed them. Theoretical and managerial implications that stress the importance of the strategic management of one’s leisure life are discussed.

Mobile apps for health professionals experiencing stress and burnout: scoping review (Preprint)

BACKGROUND The COVID-19 pandemic has exacerbated the mental health crisis within the health workforce. There is evidence that mobile apps that promote psychosocial wellness may be an effective, low-cost, and widely accessible tool to reduce stress and burnout among HCPs. OBJECTIVE The objective of this scoping review is to explore whether there are mobile-based apps tailored to HCPs for stress and burnout relief during a crisis time and explore their characteristics and key features. METHODS The Google Play and Apple app stores were searched for wellness apps using the key words “relaxation” and “mental wellness”. The first 100 search results were assessed for eligibility. This was supplemented by an online search for burnout and stress relief apps for physicians and/or nurses. The apps were included if they focused on burnout and/or stress relief and demonstrated relevance to HCPs. More specifically, the app must be marketed to HCPs, recommended by health professional organizations, or was studied for efficacy among HCPs. The details of included apps were extracted on Microsoft Excel. RESULTS Most burnout and/or stress relief apps are targeted to the general population. Few apps (n=8) were specifically built for HCPs, but the pandemic crisis has encouraged existing apps to create specific content for this group (n=7). The features within apps relevant to HCPs were largely mindfulness/meditation (n=19) and wellness education (n=12), whereas community support (n=9) and access to psychological services (n=4) were less common. CONCLUSIONS Stress and burnout are widespread and severe among HCPs during the COVID-19 crisis. Mobile apps may be a feasible tool to offer wellness interventions, but most existing apps do not provide targeted content for HCPs. For those that do, they largely focus on individual-based activities, rather than external support.

Conserved and Diversified Mechanism of Autophagy between Plants and Animals upon Various Stresses

Autophagy is a highly conserved degradation mechanism in eukaryotes, executing the breakdown of unwanted cell components and subsequent recycling of cellular material for stress relief through vacuole-dependence in plants and yeast while it is lysosome-dependent in animal manner. Upon stress, different types of autophagy are stimulated to operate certain biological processes by employing specific selective autophagy receptors (SARs), which hijack the cargo proteins or organelles to the autophagy machinery for subsequent destruction in the vacuole/lysosome. Despite recent advances in autophagy, the conserved and diversified mechanism of autophagy in response to various stresses between plants and animals still remain a mystery. In this review, we intend to summarize and discuss the characterization of the SARs and their corresponding processes, expectantly advancing the scope and perspective of the evolutionary fate of autophagy between plants and animals.
