Preschool Interventions for Self-Regulation: A Global Meta-Analytic Synthesis
No full textThe preschool years are a critical period for developing self-regulation in children. These skills predict future prosocial behavior, peer acceptance, and conflict management. They also form a key foundation for long-term academic success and mental health. Many interventions aim to build these skills. However, their effectiveness varies greatly across different cultures and socioeconomic settings. A comprehensive validation is still lacking. This study uses quantitative methods to synthesize global evidence. It examines how social-emotional learning (SEL) interventions affect the self-regulation of preschool children. The goal is to assess the overall impact of these interventions. It also identifies key influencing factors. These factors include intervention intensity, staff qualifications, family socioeconomic status, and cultural orientation. This meta-analysis followed the PRISMA 2020 and MOOSE guidelines. It included 9 intervention studies published between 2010 and 2024 from 2 international databases. These studies involved over 3,700 preschool children. The primary analysis used the Paule-Mandel random-effects model. Other methods were also used to ensure robustness. The combined effect size was Hedges’g = 0.48. This indicates a moderate- to-large positive effect of SEL interventions on self-regulation. Further analysis revealed key findings. Higher intervention intensity led to better outcomes. Teacher-led implementation was effective. Family involvement played a positive role. Interventions in collectivist cultural contexts showed stronger effects. Notably, interventions had a compensatory effect for children from low socioeconomic backgrounds. For children from high socioeconomic status families, the interventions provided an enrichment effect. The results confirm that structured SEL interventions effectively improve self-regulation in preschoolers. Beyond traditional SEL frameworks, this study proposes an integrated model. This model combines ecological, developmental, and neurocultural perspectives. It also suggests a four-level implementation strategy. The strategy covers curriculum design, teacher development, digital family engagement, and policy coordination. The study has limitations. Measurement tools were heterogeneous. Non-Western samples were underrepresented. Individual-level data were missing. Future research should use multi-modal assessments and adaptive designs. System-level simulations could also improve precision and generalizability. In conclusion, this study supports social-emotional education in early childhood. It also aids efforts to include SEL in the global education and development agenda
Location Is Back: The Influence of COVID-19 on Chinese Cities and Urban Governance
No full textThis article explores the short-term and (potential) long-term influences of COVID-19 on urban China and its governance, which was characterised by increasing mobilities and delocalised societies before the outbreak. Through the analysis of 18 observation reports in 16 cities, it is revealed that the outbreak enables the government to (re-)build a location-based urban management system with the participation of residents facing the pandemic as an external threat. A paradoxical combination of low physical mobility and high information mobility occurs. The location-based lifestyle and governance pattern has been “normalised” rather than just being a temporary response to the pandemic. The re-localisation in urban China differs from the localism in western societies as it results from the combination of the state-power-based governmental action and citizens’ participation aimed at regaining location-based ontological security. The normalisation of the re-localisation tendency may bring about fundamental changes to urban China, even “after” the pandemic
Communities in Transitions: Reflection on the Impact of the Outbreak of COVID-19 on Urban China
No full text“Community”, as a basic category of urban socio-space, has undergone evolution within academic, policy, and day-to-day life contexts in China. Through years of transitions, a kind of dual community emerged in Chinese cities before the epidemic. It encompassed a “conceptual community” based on the concept of (social) co-governance and an “experiential community” based on citizens’ daily living. The disparity between the two had given rise to a paradoxical situation in local community governance practices. The outbreak of COVID-19 brought fundamental changes to the transition process. Through the analysis of 21 recording reports during the outbreak period, we found that to contain the pandemic, the community epidemic prevention measures necessitated both these communities to overlap within a brief time frame. This led to reinforced community boundaries, the coexistence of multiple actors, the reconstruction of a sense of security-based belongingness, and the reformulation of the governance symbolic system that temporarily resolved the paradoxical governance practices. What happened under the preface of co-governance logic during the outbreak period was the coverage and shaping of the conceptual community over the experiential community, which may continue during the post-epidemic era. This study offers a relatively new approach and valuable insights into examining the long-lasting impact of the epidemic on urban social space and sustainable development in the post-epidemic era
Has Urban Cycling Improved in Hong Kong? : A Sociopolitical Analysis of Cycling Advocacy Activists’ Contributions and Dilemmas
No full textIn recent years, bicycles, as a mode of urban transportation, have become increasingly visible in the political agenda and the public debate in Hong Kong, a traditionally ‘non-cycling’ city (Zhao 2010). Although the trans-portation issue as a whole, and the urban cycling issue in particular, is traditionally a ‘public’ area in which the government plays a key role, a significant change that recently occurred is that some non- governmental actors increasingly enjoyed active and influential roles in bringing changes to the issue. This article concerns one category of emerging non-governmental actors in Hong Kong-cycling advocacy activists—to explore how they bring changes to both the cycling issue and the power relations surrounding it through interactions with other actors, especially state agencies. Besides, we will also reveal and discuss the real and poten-tial dilemmas they face.</p
The Governance Challenge within Socio-Technical Transition Processes: Public Bicycles and Smartphone-Based Bicycles in Guangzhou, China
No full textIn urban China, utilitarian cycling plays a significant role in achieving sustainable mobility. Within this context, different kinds of sharing-bicycle programs equipped with new technologies/devices emerge and extend. By comparing two generations of them in Guangzhou (China), this paper explores how new technologies impact existing modes of mobility governance. First, the technical innovations, e.g., app-based bicycle locks and micro-GPS equipment, contribute to liberating emerging private companies from existing governmental regulations based on land control. Second, the adoption of these innovations not only contributes to the accumulation of cultural and symbolic capitals based on a fashionable lifestyle but also links bicycles to personal point-to-point travel data that could be translated to economic capital. Third, the discrepancy between the dispositions of the government and private companies regarding the innovations opens an opportunity for the quick extension of sharing bicycles, which brings both positive and negative consequences on citizens’ daily travel and life. The absence of other civic actors in the decision-making process accelerates the negative consequences caused by the profit-driven fast extension of sharing bicycles and the governmental top-down governing logic. These findings provide academia with implications for understanding the impact of innovations on achieving sustainable mobility

Dancing with shackles? : The sociopolitical opportunities, achievements, and dilemmas of cycling activism in Guangzhou, China
No full textOver the last decade, urban cycling has re-emerged as a popular mode of transportation in Chinese cities. This article examines how grassroots activism contributed to this cycling renaissance by considering the case of Guangzhou. In the wake of rapid economic development, the Chinese government modified its transportation policies such that cycling was revived, with Guangzhou playing a role in the "rise, fall, and re-emergence" of China as a "cycling kingdom". We contend that these sociopolitical circumstances of economic development and political opening up provided a structural opportunity for cycling activists, who gained public visibility and institutional recognition through their strategic interaction with both governmental and nongovernmental actors. In addition, activists empowered themselves by accumulating and transforming their social capital. Their example resonated with other marginal organizations and the resulting alliances enhanced the legitimacy of cycling as a movement. Finally, we identify the dilemmas and limitations of cycling activism in urban China due to the closure of local governance channels and the perception that cycling issues are "nonurgent"

No full textMulti-dimensional impact of COVID-19 on active mobility in urban China: a scoping review of empirical knowledge
No full textActive mobility, such as cycling and walking, is assuming a growing significance in the daily lives of urban residents in China due to its positive impact on health and the environment. The impact of the COVID-19 epidemic has elicited significant changes in behaviors, perceptions, and intellectual viewpoints in this domain, potentially altering residents’ physical activities in the long-term. This scoping review seeks to delve into the multi-dimensional influence of the epidemic on active mobility in urban China. A thorough investigation of English and Chinese studies up to January 2024 was conducted, drawing from articles in Web of Science and the Chinese National Knowledge Infrastructure. Only empirical studies providing knowledge into this subject were selected in the review, which comprised 20 studies in total. This review indicates that the influence of COVID-19 on active urban mobility in China has exhibited contradictory outcomes in terms of behavior. Besides, the experiences during the epidemic have significantly shaped citizens’ attitudes and understanding of active mobility. The repercussions of the epidemic and the ensuing restrictions exacerbate the existing challenges faced by women, particularly those who are married, the older adult, and individuals with low incomes. The results exhibit both resemblances and idiosyncrasies when juxtaposed with prior research conducted in different nations. This analysis also offers valuable insights for improving active mobility across individual, organizational, and socio-political realms. The current state of empirical understanding in this field underscores the need for further research endeavors employing diverse methodological approaches and increased emphasis on the transformations anticipated in the post-epidemic era
Fabrication and Thermal Stability Characterization of Ru Electrode Used for High Power Contact RF MEMS Switch
No full textThis paper presents the fabrication and thermal stability of the Ru electrode used for high power Ru-Au contact RF MEMS switch with microspring contact design. Here we develop a new process with bilayer lift-off and strain release layer to get the 3000 angstrom Ti/Au/Ru electrode with excellent smooth edge for high power handling and low loss. Furthermore, the thermal test at 400 degrees C, 500 degrees C and 600 degrees C over 1 hour has been done. Investigation of the surface with SEM and EDX shows that the electrode has a good thermal stability at 400 degrees C, which is proper for high power handling.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000327183000069&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Engineering, BiomedicalEngineering, Electrical & ElectronicNanoscience & NanotechnologyEICPCI-S(ISTP)
