Domestication theory in action: Indonesian Twitter corpus analysis during distance learning

This research aims at analyzing how COVID-19 discourse in the world of education unfolds in the Indonesian Twittersphere by separating public discourse in transition periods, large-scale social restrictions (PSBB), and imposition of emergency restrictions toward community activities (PPKM) and PPKM level 1 to 4. This research used qualitative approach and employed the Domestication Theory to provide a deeper understanding of how individuals integrate technology into their everyday lives. The dataset consisting of 3,196,627 tweets from two keywords and two hashtags was collected and analyzed using corpus linguistics techniques. This study found the emergence of the five main theme groups suggests that users have tried to make sense of and adapt to this new digital learning environment, while also expressing their frustrations and concerns. This highlights the importance of understanding how users domesticate technology and incorporate it into their social and cultural practices. The practical implications of this research include the need to address not only the technical aspects of online learning but also the psychological and social well-being of students, as they navigate this new learning environment.

Strobe training as a visual training method that improves performance in climbing

IntroductionStrobe training is a form of visual training where the athlete has to practice during intermittently dark conditions. Strobe training improves visual, perceptual, and cognitive skills, which will enhance athletic performance. Strobe training can influence multiple training components in climbing: psychological, tactical, physical, and technical training.Materials and methodsThe study was conducted on 17 elite climbers from Romania (10 male and 7 female), representing the entire National Youth Climbing Team. The research group was divided into a control group (n = 8) and an experimental group (n = 9). The used instruments were the Cognitrom battery (for cognitive skills, such as spatial skills and reactivity), the Witty SEM system (for motor-cognitive skills, such as cognitive agility, visual processing speed, and visual memory), and the International Rock Climbing Research Association (IRCRA) performance-related test battery for climbers (climbing-specific motor skills). The experimental group had 20 strobe training sessions, which took place during one calendar year, as an additional session to their climbing schedule done with their principal trainer. The strobe session was once a week, depending on the periodization of the macrocycle (preparatory, competitional, and transition periods). The control group and the experimental group had similar climbing training sessions during the 1-year macrocycle in terms of intensity and volume of their training.ResultsStrobe training improved on-sight performance (d = 0.38) and red-point performance (d = 0.36). Strobe training improved the majority of cognitive skills [all spatial skills (d = 1.27 for mental image transformation; d = 1.14 for spatial orientation; d = 1.59 for image generation) and simple reaction time (d = 0.99)]. Strobe training improved all motor-cognitive skills (d = 0.16 for visual memory; d = 1.96 for visual memory errors; d = 1.39 for visual processing speed; d = 1.94 for visual processing errors; d = 1.30 for cognitive agility). Strobe training improved many climbing-specific parameters (flexibility and upper body strength) (d = 0.44 and d = 0.47 for flexibility parameters; d = 0.50 to 0.73 for upper body strength parameters).DiscussionStrobe training is an effective training method for enhancing performance that should be used on more experienced climbers. It acts more on spatial skills, rather than on reactivity skills, developing the visual-motor coordination system. Strobe training has greater effects on climbers aged below 16 years, as youth athletes rely more on visual input compared to adults. The improvement in climbing-specific variables was due to the additional climbing session done weekly. Strobe training acts more on the cognitive component of training than on the motor component of training in climbing.

Relationships between moderate vigorous physical activity, motor- and health-related fitness and motor skills in children

Background: Childhood is an important transitional period for the development of healthy physical activity (PA) behaviours, so it is important to understand its impact on a healthy lifestyle.Aim: This study aimed to determine the influences of sex, socioeconomic status (SES) and body composition (BC) on the relationships between PA, motor skills, motor- and health-related physical fitness in 5–8-year-olds.Setting: Participants were a subsample consisting of 299 children (150 boys, 149 girls, mean age 6.83 ± 0.96 years) from the Exercise, Arterial Modulation and Nutrition in Youth South Africa study (ExAMIN Youth SA).Methods: Anthropometric measures, health-related physical fitness (HRPF), motor-related physical fitness (MRPF), objectively measured PA and demographic information were determined.Results: Only 66% achieved the recommended 60 min of daily moderate vigorous physical activity (MVPA) with 19% classified as having unhealthy body composition (11% overweight, 8% obese). Fat-free mass and SES revealed small-to-moderate influences on the relationship between MVPA, standing broad jump (SBJ; r = 0.32), predicted VO2max (r = 0.28) and beep levels (r = 0.22). For MRPF, the quality of running (r = 0.12) and balancing were associated with MVPA. Adjusting for sex, BC and SES in the relationship between PA with HRPF and MRPF, reductions in most correlations were observed.Conclusion: Moderate vigorous physical activity levels were positively associated with HRPF, MRPF and some motor skills in 5–8-year-olds. Socioeconomic status (lower parental income, employment and education negatively influenced the association between MVPA and fitness [beeps, SBJ, O2max]).Contribution: This study provides knowledge with regard to the use of accelerometer for baseline data for PA, MRPF, HRPF as well as motor skills in South African children.

Rapid Restratification Processes Control Mixed Layer Turbulence and Phytoplankton Growth in a Deep Convection Region

AbstractThe Gulf of Lion, Northwestern Mediterranean Sea, is one of few oceanic regions where deep convection occurs. We investigate the restratification following a convection event using measurements from an ocean glider equipped with turbulence microstructure sensors. This unique combination of instruments provides a high‐resolution description of the mixed layer with regard to turbulence, stratification and chlorophyll. We observe a rapid restratification process that proceeds over a timescale of days to one week. We find that restratification exerts a leading order control on surface mixed layer turbulence variability, as abrupt changes in turbulence dissipation rates are associated with the formation of near‐surface stratification. The near‐surface formation of stratification occurs through both the diurnal variability in surface buoyancy fluxes and through lateral advective processes. We conclude that daily near‐surface processes that influence stratification control mixed layer turbulence levels, and thus the phytoplankton response in the critical transition period to spring bloom.

ECMWF Ensemble Forecasts of Six Tropical Cyclones That Formed during a Long-Lasting Rossby Wave Breaking Event in the Western North Pacific

The ECMWF‘s ensemble (ECEPS) predictions are documented for the lifecycles of six tropical cyclones (TCs) that formed during a long-lasting Rossby wave breaking event in the western North Pacific. All six TC tracks started between 20° N and 25° N, and between 136° E and 160° E. All five typhoons recurved north of 30° N, and the three typhoons that did not make landfall had long tracks to 50° N and beyond. The ECEPS weighted mean vector motion track forecasts from pre-formation onward are quite accurate, with track forecast spreads that are primarily related to initial position uncertainties. The ECEPS intensity forecasts have been validated relative to the Joint Typhoon Warning Center (JTWC) Working Best Track (WBT) intensities (when available). The key results for Tokage (11 W) were the ECEPS forecasts of the intensification to a peak intensity of 100 kt, and then a rapid decay as a cold-core cyclone. For Hinnamnor (12 W), the key result was the ECEPS intensity forecasts during the post-extratropical transition period when Hinnamnor was rapidly translating poleward through the Japan Sea. For Muifa (14 W), the key advantage of the ECEPS was that intensity guidance was provided for longer periods than the JTWC 5-day forecast. The most intriguing aspect of the ECEPS forecasts for post-Merbok (15 W) was its prediction of a transition to an intense, warm-core vortex after Merbok had moved beyond 50° N and was headed toward the Aleutian Islands. The most disappointing result was that the ECEPS over-predicted the slow intensification rate of Nanmadol (16 W) until the time-to-typhoon (T2TY), but then failed to predict the large rapid intensification (RI) following the T2TY. The tentative conclusion is that the ECEPS model‘s physics are not capable of predicting the inner-core spin-up rates when a small inner-core vortex is undergoing large RI.

The changes in biethnic acceptance across daily settings and biethnic adolescents' psychological well-being during middle school transition.

Patterns of biethnic adolescents' perceived biethnic acceptance across families, peers, and school contexts were examined during the transition from elementary to middle school in South Korea. We also examined how the transition patterns were related to their psychological outcomes during this period. Utilizing 2-wave data (2017 and 2019) from the Panel Survey of Korean Multicultural Youth Adjustment, a latent transition analysis was conducted. Participants were biethnic adolescents who were in 5th or 6th grade at Wave 1 (N = 245; 51.02% female; Mage = 11.38). Their fathers were Korean, and mothers were immigrants from neighboring countries. Familial ethnic socialization, peer discrimination, and school multicultural climate scores were used as indicators of biethnic acceptance. Outcomes of self-esteem, depression, and biethnic affirmation were also examined. Latent profile and transition analyses yielded two groups (i.e., high acceptance and low acceptance) at each wave and four transition patterns (i.e., high-high, low-high, low-low, and high-low). Compared to high-high group, which was the most prevalent group, low-low and high-low groups reported lower self-esteem and ethnic affirmation, and greater depression at Wave 3. While for the majority of participants, their daily settings continued to be high in biethnic acceptance across the transition period, most at risk were those who perceived a decrease in biethnic acceptance in their daily settings. Results shed light on the need for support to maintain the context of high biethnic acceptance surrounding biethnic adolescents for their psychological well-being in school transitions.

Trajectories of mental health across the primary to secondary school transition

AbstractBackgroundAdolescence is a period of profound developmental change during which the prevalence of mental health problems starts to increase. It also typically coincides with a school transition. Understanding mental health trajectories through school transition is important to inform interventions to support young people's mental health during this period.MethodsIn a longitudinal study with three assessment points spaced six months apart spanning the transition from primary (T1 = end of primary school [Year 6]) to secondary school (T2 = beginning of the first year secondary school [Year 7]; T3 = end of first year of secondary school [Year 7]) we carried out a latent class growth analysis of symptoms of common mental health problems. Young people (mean age at baseline of 11.2 years, standard deviation 0.29; 46.8% female; 53.2% male) from South East England (n = 1861) were included. We modelled emotional problems, conduct problems, hyperactivity and peer problems in parallel over the transition period. Individual‐level variables: socioeconomic status (SES), special educational need(s) (SEN), gender, negative life events (NLEs) and being worried about transition were tested as predictors of trajectory class membership using multinomial logistic regression.ResultsA model with four trajectory classes provided the best fit to the data: ‘persistently elevated’ mental health problems, ‘emotional and peer problems’, ‘hyperactivity and conduct problems’ and ‘persistently low’ mental health problems. Class membership was differentially predicted by the individual‐level variables.ConclusionsYoung people from low SES backgrounds, those with SEN and those who have experienced two or more NLEs are more likely to exhibit trajectories with elevated mental health difficulties through the transition to secondary school. Young people who were worried about transition were more likely to belong to a trajectory class characterised by elevated emotional problems.

Beyond liberal justice? Decolonising Colombian transitional justice through victims’ participation and indigenous rights

ABSTRACT Transitional justice is a particular approach to justice for periods of transition to peace and democracy. It has been standardised in handbooks by profiling experts, often from the Global North, with meagre local participation in practice. It is criticised for having a liberal conception of justice that reproduces forms of structural discrimination against ethnic peoples. The Peace Agreement between Colombia and the FARC-EP signed in November 2016 addresses this criticism through a System for Truth, Reparation, and Guarantees of No-Repetition that includes a Special Jurisdiction for Peace (JEP) that must impose sanctions following a dialogical process with victims. The tribunal requires their participation to determine how perpetrators must repair the damages caused during the armed conflict. When victims belong to ethnic groups, their participation has influenced the tribunal to make decolonising decisions. In a ground-breaking process, the JEP incorporated indigenous perspectives into its justice procedures, acknowledging the role of the Territory to ethnic groups and officially recognising it as a living being that is a right-bearer that deserves reparations. This article analyses the achievements of such a process and underlines some challenges. From a practical perspective, it contributes to broader debates regarding indigenous rights and victims’ participation in transitional justice.

Decline of a national icon: Derogatory representations of the Romanian peasant in recent television programs

Intellectuals and artists have been crafting an image of the Romanian peasant as the building block of the nation since the second half of the 19th century. The process went hand in hand with the modernization of the elites, and the peasant was thus mainly ‘discovered’ within the cultural framework of Romanticism, as the ‘eternal autochthon’ (Mihăilescu,2017, p.173), creator of the specific Kultur of the Romanian people. However, dramatic social transformations such as the difficult transition period of the ʹ90s have shifted the focus from a complimentary representation of the peasant as the national foundation – and all the positive characteristics of his/her habitus in terms of material, spiritual and aesthetic values– to a rather alienated and anachronistic figure coming across as a burden that has to be carried into modernity by the enlightened social strata. This paper uses visual analysis, grounded in Barthesian semiotics, to explore the changes in modes of representation of the peasant in popular media from the depository of national values to a marginal lower class, striving to keep up with the urban lifestyle. Various portrayals of peasants in TV series and sketches, movies and memes point to the degradation of the peasant figure in the public imagination. Images of poverty, bad taste and a lack of hygiene seem to pollute the bodies, garments and home environments of the rural characters, with a toxic effect on their language and behaviour as well. Although there have always been derogatory images of the peasants in the discourse of the elites (Mihăilescu also coined the term ‘domestic primitive’ for the representation associated with the historical tendency to portray the peasants as a backward population incapable of progress), in recent times this tendency has prevailed, especially with the rural-themed successful TV series Las Fierbinți, for mainly ideological reasons which will be discussed. Thus, apart from deconstructing a national myth, I argue that the representation of contemporary peasants and their degenerating habitus also contributes to the polarization in the Romanian society.

Provenance signature and tectono–sedimentary setting of the Permian Shihezi formation (Ordos basin, China): Insights from geochemistry and detrital zircon U–Pb dating

During the depositional period of the Permian Shihezi Formation, the southern margin of the Ordos Basin was a key location for studying the tectonic movement of the North China Craton (NCC) and South China Blocks. The sedimentary environment was the first period of complete transition from marine to continental. However, the distribution of sediments controlled by a multi–provenance supply and the response of deposition to tectonics remain ambiguous, and the restoration of paleogeography remains in the qualitative stage, restricting the study of larger-scale tectono–sedimentary patterns. Based on field profiles and core observations, the paleocurrent direction, lithic fragments, heavy mineral assemblages, rare earth element distribution patterns, 11 detrital zircon U–Pb age datasets, and discrimination diagram of major and trace elements, the provenance signature and tectono–sedimentary setting were revealed. The results indicated that there are three main provenances in the southern margin of the Ordos Basin: North Qilian and western and eastern sections of the North Qinling Orogenic Belt. The tectonic setting of the North Qilian was a continental island arc, and the North Qinling was transformed from a passive to an active continental margin. Owing to the continued intense tectonic activities of the North Qilian, a braided river delta with a large sedimentary range developed in the west, and it was mixed with detrital sediments from the western section of the North Qinling with weak tectonic activity in the central. Affected by the uplift of the southern North China Craton, the sedimentary environment in the eastern range was unstable, and the thickness distribution of sandy sediments in the braided river delta was uneven. Refinement of provenance and deposition has important implications for the study of basin–mountain coupling relationships and paleogeographic reconstruction in the southern Ordos Basin and provides a basis for the study of collision evolution of the North and South China Blocks in the Permian.

For the greater good: modern China’s struggle on housing shortage

The examination of housing shortages in China presents a fascinating subject that is rarely directly addressed. This topic not only captures our interest due to the irony in a communist country but also in light of the profound transformation of Chinese society, evolving from an agrarian civilization to a modern industrialized state. The objective of this essay is to establish a comprehensive framework that encompasses economic, social, and architectural narratives as an integrated whole. This essay delves into the historical trajectory of housing shortages in modern China, tracing the evolution of this issue within Chinese society since the founding of the communist regime in 1949. Given China’s unique industrial and residential policy framework, housing provision is intrinsically linked to state-owned factories and residential certification, commonly referred to as hukou. As the political and economic foundations have shifted over time, so too has the root cause of housing shortages. In addition to general historical and theoretical research, we have undertaken an in-depth examination of Lanxi City, one of the industrial clusters established in China. The case study of Lanxi City involves a series of visits and interviews conducted within local factories and communities. Our analysis identifies two distinct phases in this evolution: the “fundamentalist communist era” and the transitional period toward a market economy. Each of these eras can be further subdivided into four distinct phases, providing a more nuanced perspective. Our findings reveal that various housing distribution mechanisms have contributed to the issue of housing shortages. During the first era, housing shortages were primarily a result of hukou restrictions, industrial disparities, sluggish construction processes, and corporate profit considerations. In the latter phase, spanning the 1980s and 1990s, housing shortages were exacerbated by escalating costs and a slow rate of housing unit replenishment. As the new millennium unfolded, real estate bubbles compounded the housing crisis, with older neighborhoods ill-suited for modern living. Our interviews and visits complemented our literature research, offering valuable insights into the systemic exploitation of specific groups in pursuit of broader goals, hence the title. This paper underscores the housing shortage in China as a consequence of economic disparities between urban and rural regions, as well as between the prosperous East coast and the underdeveloped West hinterland.

Insights from the 2nd China intelligent sleep staging competition.

Artificial intelligence (AI) is quickly advancing in the field of sleep medicine, which bodes well for the potential of actual clinical use. In this study, an analysis of the 2nd China Intelligent Sleep Staging Competition was conducted to gain insights into the general level and constraints of AI-assisted sleep staging in China. The outcomes of 10 teams from the children's track and 13 teams from the adult track were investigated in this study. The analysis included overall performance, differences between five different sleep stages, variations across subjects, and performance during stage transitions. The adult track's accuracy peaked at 80.46%, while the children's track's accuracy peaked at 88.96%. On average, accuracy rates stood at 71.43% for children and 68.40% for adults. All results were produced within a mere 5-min timeframe. The N1 stage was prone to misclassification as W, N2, and R stages. In the adult track, significant differences were apparent among subjects (p < 0.05), whereas in the children's track, such differences were not observed. Nonetheless, both tracks experienced a performance decline during stage transitions. The computational speed of AI is remarkably fast, simultaneously holding the potential to surpass the accuracy of physicians. Improving the machine learning model's classification of the N1 stage and transitional periods between stages, along with bolstering its robustness to individual subject variations, is imperative for maximizing its ability in assisting clinical scoring.

Calcareous nannofossil records and the migration of the Agulhas Return Current during the last 40 kyr

The Agulhas Return Current (ARC) transports warm tropical and subtropical waters eastward into the southern Indian Ocean. It plays a crucial role in the oceanographic connections between the Indian, Atlantic, and Southern oceans. Modern oceanographic observations show that the latitudinal position of the ARC varies interannually. However, its historical positional variations remain poorly understood. Calcareous nannofossils can be a good indicator of ancient current migration, although their record in the Southwest Indian Ocean is poorly studied. This research aims to understand the characteristics and downcore variation of the calcareous nannofossil assemblages and trace the record of the ancient ARC. To achieve these goals, this study analyzed pelagic sediments of multicore 34IV-SWIR-S021MC03, 34IV-SWIR-S032MC04, and 34IV-SWIR-S040MC05 from the Southwest Indian Ocean. A total of 13 nannofossil species have been identified. The assemblages belong to the subtropical convergence zone regime. They are characterized by warm and cold water species, dominated by Emiliania huxleyi, Calcidiscus leptoporus, Gephyrocapsa muellerae, and Florisphaera profunda. According to the AMS14C age model and phytoplankton ecological signatures, this study establishes a calcareous nannofossil indicator to trace the migration of the ancient ARC during the last 40 kyr. The result shows three periods of migration: 40–22 kyr, the ancient ARC was in the far north and was moving southward; 22–14 kyr, a transitional period, the ancient ARC was moving northward; 14–3 kyr, the ARC was moving southward. This further suggests that the migration of the ancient ARC is more complex than the two recognized phases, and there were essential turning points around the last glacial maximum period. It also acknowledges that the ancient ARC is sensitive to interglacial periods and can be influenced simultaneously by the Southern Hemisphere monsoon and westerly winds.

The MOSAiC Distributed Network: Observing the coupled Arctic system with multidisciplinary, coordinated platforms

Central Arctic properties and processes are important to the regional and global coupled climate system. The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) Distributed Network (DN) of autonomous ice-tethered systems aimed to bridge gaps in our understanding of temporal and spatial scales, in particular with respect to the resolution of Earth system models. By characterizing variability around local measurements made at a Central Observatory, the DN covers both the coupled system interactions involving the ocean-ice-atmosphere interfaces as well as three-dimensional processes in the ocean, sea ice, and atmosphere. The more than 200 autonomous instruments (“buoys”) were of varying complexity and set up at different sites mostly within 50 km of the Central Observatory. During an exemplary midwinter month, the DN observations captured the spatial variability of atmospheric processes on sub-monthly time scales, but less so for monthly means. They show significant variability in snow depth and ice thickness, and provide a temporally and spatially resolved characterization of ice motion and deformation, showing coherency at the DN scale but less at smaller spatial scales. Ocean data show the background gradient across the DN as well as spatially dependent time variability due to local mixed layer sub-mesoscale and mesoscale processes, influenced by a variable ice cover. The second case (May–June 2020) illustrates the utility of the DN during the absence of manually obtained data by providing continuity of physical and biological observations during this key transitional period. We show examples of synergies between the extensive MOSAiC remote sensing observations and numerical modeling, such as estimating the skill of ice drift forecasts and evaluating coupled system modeling. The MOSAiC DN has been proven to enable analysis of local to mesoscale processes in the coupled atmosphere-ice-ocean system and has the potential to improve model parameterizations of important, unresolved processes in the future.

Predicting calcium status in early lactation multiparous Holsteins using milk constituent analysis

Due to the unique challenges of supporting milk production, subclinical hypocalcemia (SCH) is common among early lacta­tion dairy cows. Though SCH immediately following parturi­tion may constitute normal adaptation to the transition period, there is growing evidence that cows with SCH beyond 4 days postpartum (DIM) have developed dyscalcemia, a pattern of calcium dysregulation that has been associated with negative health and production outcomes. Despite prevalence of dyscal­cemia ranging from 25% to 45%, identifying cows with dyscal­cemia remains a major challenge on commercial dairies. Our objective was to develop an algorithm for predicting dyscalce­mia status using Fourier-transform mid-infrared spectroscopic (FT MIR) analysis of milk samples at 3 and 4 DIM.

Exploring the Relationship between the Dynamics of the Urban–Rural Interface and Regional Development in a Post-Socialist Transition

This study offers, by an empirical analysis, another perspective on post-socialist development, highlighting the role of the urban–rural interface in regional dynamics. The current literature on the relationships between both issues is not too rich and our paper analyzes the relationships between core cities, their peri-urban areas, and their regions, through a comparative overview of their growth over the last three decades. Romania, as a special case study for a contradictory transition, due to the great step from a drastic dictatorial regime to a democracy and a market economy, is a good example to test these complex relationships. Considering the new development trend at the urban–rural interfaces, our key idea was to depict their contribution to regional development (NUTS 3) compared to city cores. The second question was how this differentiated contribution can be measured, using the simplest tool. The starting point was the fact that population dynamics reflect all changes in the city core and at the urban–rural interface, and less so at a regional level. Consequently, we selected the dynamics of the number of inhabitants for the first two, as well as the dynamics of GDP per capita at the regional level. We found higher and significant correlations between GDP per capita and urban–rural interfaces, but no significant correlations in the case of city cores. Our conclusion is that, in the transition period, the dynamics of urban–rural interfaces influenced more regional development dynamics, than those of city cores. This means that urban–rural interfaces amplify the development coming from cities, adding their own contribution and then dissipating it regionally. Future research should identify what the urban–rural interface offers to regions, in addition to the city core.

Competing forces: Subsistence strategies and human-carnivore interactions during the middle to Upper Palaeolithic transition in Northern Iberia

The comparative assessment of dietary choices as part of landscape use strategies deployed by Neanderthal and Anatomically Modern Human populations in Eurasia constitutes a fundamental avenue of Palaeolithic research. The increasing number of taphonomic assessments enables a better understanding of what remains were brought to sites by human hunters versus mammalian carnivores or raptors. A zooarchaeological approach can further elucidate the spatio-temporal dynamics of interaction between carnivores and human populations in terms of landscape use and prey choice during this transitional period. To achieve this objective, we conducted an examination of zooarchaeological and taphonomic data, carnivore indices, and other relevant variables across 36 Middle and Early Upper Palaeolithic sites in northern Iberia. These sites encompass 126 archaeological layers dating from 50,000 to 30,000 years ago. Our comprehensive bibliographic meta-analysis reveals that human occupations by both groups at sites across the region were punctuated by episodes influenced by carnivores. This observation implies that human occupations in northern Iberia during Marine Isotope Stage 3 were generally characterised by instability and limited to short periods, often seasonal in nature. From a zooarchaeological perspective, the combined assessment of taxonomic data, species richness and assemblage diversity highlights that the range and proportion of species acquired by these different human groups are similar, although Anatomically Modern Humans engaged in a sustained trend towards increasing dietary diversification even at sites with assemblages heavily dominated by one taxon.

New Directions in Geroscience: Integrating Social and Behavioral Drivers of Biological Aging.

The "geroscience hypothesis" posits that slowing the physiological processes of aging would lead to delayed disease onset and longer healthspan and lifespan. This shift from a focus on solely treating existing disease to slowing the aging process is a shift toward prevention, including a focus on risk factors found in the social environment. While geroscience traditionally has focused on the molecular and cellular drivers of biological aging, more fundamental causes of aging may be found in the social exposome - the complex array of human social environmental exposures that shape health and disease. The social exposome may interact with physiological processes to accelerate aging biology. In this commentary, we review the potential of these insights to shape the emerging field of translational geroscience. The articles in this special issue highlight how social stress and social determinants of health are associated with biomarkers of aging such as inflammation, epigenetic clocks, and telomeres, and spotlight promising interventions to mitigate stress-related inflammation. For geroscience to incorporate the social exposome into its translational agenda, studies are needed that elucidate and quantify the effects of social exposures on aging and that consider social exposures as intervention targets. The life course perspective allows us to measure both exposures and aging biology over time including sensitive periods of development and major social transitions. In addition, given rapid changes in the measurement of aging biology, which include machine learning techniques, multisystem phenotypes of aging are being developed to better reflect whole body aging, replacing reliance on single system biomarkers. In this expanded and more integrated field of translational geroscience, strategies targeting factors in the social exposome hold promise for achieving aging health equity and extending healthy longevity.

Emerging in‐migration of urban young adults engaging in rural tourism in China

AbstractDuring the rapid urbanisation of China in recent decades, a vast proportion of the labour force left rural hometowns to find employment in cities. In the context of rural revitalisation and tourism development in China, rural tourism is booming, bringing many tourism‐related jobs to the countryside. As a result, some young urban adults have moved to work in rural areas. Based on in‐depth interviews in Su village in Nanjing, China, this study seeks to investigate the motivations of those who choose to work in the countryside and the connections between this and stages in the life course of urbanites in the 90s generation, a cohort that is quite distinct from older cohorts. This study finds that the motivations of these younger workers range from career development and cost reduction to a preference for a rural lifestyle. Engaging in tourism‐related work in rural areas is associated with two life courses (work career and individual/family pathway). This study also finds that the cohort working rural tourism in rural areas is differentiated: while some pursue career development, others aim to escape certain pressures and obligations by ‘lying flat’ in the more congenial rural setting where living costs are lower than in cities. Pro‐tourism rural areas, with an acceptable distance from cities, become valuable places for these youth to resist or balance their life in front of increasingly competitive urban life during their adult transitional period.
