Rethinking development as structural transformation
Problematic internet use and aggression in Chinese middle school students
Introduction: Problematic internet use (PIU) has become a prevalent concern worldwide and is associated with increased aggression. However, the underlying effect of PIU on aggression remains unclear. In this study, we aimed to investigate the potential influence of reality social connectedness (RSC) on the relationship between PIU and aggression. Methods: We used cross-sectional data from a large survey conducted among middle school students in f…
Navigating Development Cooperation for Structural Transformation
Psychiatric disorder, traumatic experience and social deprivation in distinct subtypes of suicide attempt
These differences of attempted suicide appeared to result from the distinct social factors in China and the UK. Weakened social bonds could be a new intervention target for Chinese young men attempted suicide, whereas chaotic lifestyles for that of British young men attempted suicide
The mediation role of low social-connectedness in association of internet gaming disorder and anger among adolescents
The effect of IGD contribution to anger might be not only directly accomplished by IGD itself, and also influenced by indirectly mediation of low social-connectedness with reality, especially in the negative dimension
The Measurement‐Impact Gap
The role of Development Finance Institutions (DFIs) in achieving the Sustainable Development Goals (SDGs) is a topic of growing scholarly importance. While existing literature has mapped the thematic scope of this field, a critical diagnosis of its intellectual structure and inherent biases is missing. This study addresses that gap by using a bibliometric analysis of 271 articles from the Web of Science database not simply to describe the literat…
The mediating role of social connectedness and negative cognitive emotion regulation in the association between problematic Internet use and depression among adolescents
Introduction: While the relationship between adolescent problematic Internet use (PIU) and depression has been extensively researched, few studies have investigated the role and mechanisms of social connectedness (SC) in this context. This study aimed to investigate the mediating effect of social connectedness (SC) and cognitive emotion regulation (CER) in the relationship between PIU and depression. Methods: We conducted a cross-sectional study …
Post-Occupancy Evaluation of the Improved Old Residential Neighborhood Satisfaction Using Principal Component Analysis
Recently, many Chinese cities have initiated improvement projects aimed at enhancing living conditions in older residential neighborhoods. Urban improvement should be closely linked to the needs of occupants to determine “what to improve”. Governmental initiatives and the various stakeholders involved in the project influence the impact of improvement efforts. The objectives of the study are essential to identify the factors influencing occupants…
The attitudes of nonpsychiatric nurses towards mental disorders in China
High education level, long residence in urban, personal care experience and the psychiatric clinical practice were associated with the discrimination of nonpsychiatric nurses towards mental disorders. Further exploring practical strategies to optimize the psychiatric clinical practice experience of nonpsychiatric nurses could help improve their attitudes towards mental disorders
Suicidal ideation and suicide attempts among students aged 12 to 24 after the lifting of Covid-19 restrictions in China
Suicidal ideation and suicide attempts remain prevalent among young people in China. The potential associated factors identified in our study may be useful for targeting appropriate psychosocial interventions and developing mental health policies

Does digital economy agglomeration promote green economy efficiency? A spatial spillover and spatial heterogeneity perspective
The combined impact of social networks and connectedness on anxiety, stress, and depression during Covid-19 quarantine
Introduction: The COVID-19 pandemic and associated quarantine measures have precipitated a surge in mental health disorders, particularly depression and anxiety. Government policies and restrictions on physical activity have contributed to this phenomenon, as well as diminished subjective social connectedness and exacerbated objective social isolation. As two dimensions of social isolation, it is worth noting that subjectively perceived social co…
Differences among fathers, mothers, and teachers in symptom assessment of ADHD patients
Results concluded that fathers did not appear to be an appropriate candidate for evaluation. When using the SNAP-V for assessment, it should be comprehensively considered from both the scorer and symptom dimensions
Spatial Difference and Convergence of Ecological Common Prosperity
Analyzing the spatial difference and convergence of ecological common prosperity (ECP) in the Yellow River Basin (YRB) will be beneficial for the environmental governance and multi-regional economic coordination. Based on the panel data of 97 cities in the YRB from 2003 to 2019, this paper measured and analyzed the index of ECP, the Gini coefficient of ECP, and the convergence of ECP. The results indicate that the ECP of YRB shows a steady growth…

Peer effects in local government decision-making
Effect of Repeated Home Quarantine on Anxiety, Depression, and PTSD Symptoms in a Chinese Population During the Covid-19 Pandemic
Increasing quarantine times was associated with moderate to severe depression symptoms, but not with an increase in symptoms of anxiety or PTSD
Covid-19 Information Overload, Negative Emotions and Posttraumatic Stress Disorder
COVID-19 information overload, anxiety, depression, and PTSD are negative psychological states, and each variable is closely linked with the others, suggesting the need for potential psychological interventions at specific times. Practical public training, such as crisis coping and information filtering, is essential. Regulation of technology companies is also essential
Differential Effects of Anxiety on Internet Gaming Disorder
Anxiety was a predictor of IGD, with statistically significant group differences in total anxiety, as well as the dimensions of physiological anxiety, social correlation, and sensitivity. The timely assessment of anxiety in children and adolescents, training social skills, and facilitating effective integration into society could be effective ways of reducing the incidence and impact of IGD
Individual difference in perceptions of social structure
This study examined the extent to which social standing based on reputation (i.e., popularity), affective regard (i.e., peer acceptance and peer rejection), and affiliation‐network centrality (i.e., degree, betweenness, and closeness centrality), in addition to gender and grade in school, predicted children's accuracy in detecting affiliation patterns within peer networks. Third through fifth‐grade students ( n = 400) were from three semi‐rural e…
Long-term finance provision
Despite its practical significance in promoting long-term economic growth, long-term finance is often in short supply, especially in developing countries. Governments in both developed and developing countries have established national development banks (NDBs) to provide much-needed long-term loans. We have built the first database on NDBs worldwide to systematically examine whether NDBs lend longer than commercial banks in deciding the maturity …
Transformation Towards Renewable Energy Systems
Our paper seeks to evaluate the role of development financing institutions (DFIs) in fostering renewable energy transformations. Whereas the conventional approach to renewable energy finance emphasizes the bankability of individual projects, we advance an alternative approach for the role of DFIs in overcoming system-level constraints to enhance renewable energy transformations. We identify four constraints, namely, the incumbent entrenchment of …
Functional Connectivity of Nucleus Accumbens and Medial Prefrontal Cortex With Other Brain Regions During Early-Abstinence Is Associated With Alcohol Dependence and Relapse
Background: Alcohol dependence (AD) is a chronic recurrent brain disease that causes a heavy disease burden worldwide, partly due to high relapse rates after detoxification. Verified biomarkers are not available for AD and its relapse, although the nucleus accumbens (NAc) and medial prefrontal cortex (mPFC) may play important roles in the mechanism of addiction. This study investigated AD- and relapse-associated functional connectivity (FC) of th…
What are public development banks and development financing institutions ? ——qualification criteria, stylized facts and development trends
Public development banks and development financing institutions are experiencing renaissance worldwide, but systematic academic research is patchy. The bottleneck mainly boils down to the lack of data, which has constrained the meaningful research on the rationales of establishing PDBs and DFIs and reasons for their successes and failures. To fill the gap, we aim to answer the fundamental question of “what PDBs and DFIs are” by proposing five qua…
Matching Risks with Instruments in Development Banks
This paper explores how development banks should deploy appropriate financial instruments to encourage real economic risk-taking while minimizing financial engineering risks. We distinguish real economic risks from financial engineering or intermediary risks and argue that using complex financial instruments to leverage additional private financing may undermine policy steer and lead to too much risk being taken by development banks. We then expl…
China's Development Finance
This article explores the implications of China's rise for global reporting and monitoring systems (RMSs) in the field of development cooperation. Beyond its fast?growing – albeit still modest – foreign aid, China has emerged in the last decade as a globally pre?eminent source of development finance. While China's endeavours are comparable to previous rising powers that strived to build linkages into global commodity chains and to participate in …
Scales of Power in Water Governance in China
Theories that explain the governance of water, such as integrated river basin management and multilevel water governance, point to scalar configurations of power as critical determinants of success (or failure). This article explains how the scalar configurations of power in water governance mirror those of the Chinese State, and influence water governance in powerful ways. We use the case of the Yangtze River and Shanghai, a megacity in the Yang…

Should National Development Banks be Subject to Basel III
We address the question: What are the potential impacts of Basel III capital framework for National Development Banks (NDBs) upon their ability to fulfil their developmental mandate? We compare three large NDBs’ experiences with Basel III implementation: Brazilian Development Bank, China Development Bank and Germany’s KfW. We find that the biggest constraint from Basel III comes less from its levels of comprehensiveness and complexity and more fr…
Exploring China’s Impacts on Development Thinking and Policies
In this article, we explore the impacts, actual and potential, of China’s development experiences upon development thinking and policies elsewhere. New Structural Economics, a theoretical innovation by Professor Justin Yifu Lin drawing on a longer tradition of pragmatic ‘learning by doing’ development strategies, provides a framework in which three agendas stand out: structural transformation as a policy priority; the return of industrial policy;…

Mental health and psychosocial problems among Chinese left-behind children
A flying goose chase
This paper examines whether rising wages have driven Chinese manufacturers to make foreign direct investment abroad to reduce the costs of production. We match the Chinese Ministry of Commerce’s register of Overseas Direct Investments with China’s Industrial Enterprise Survey data from 2011 to 2013 and annual average wage data for prefecture-level cities. Although high-income developed economies are the preferred destinations for Chinese manufact…
The Association Between Medication Adherence and Disease Stability in Patients with Severe Mental Disorders and Area Variation
Item Response Models in Psychometrika and Psychometric Textbooks
Item response theory modeling articles from 83 years of Psychometrika are sorted based on the taxonomy by Thissen and Steinberg (1986). Results from 377 research and review articles indicate that the usual unidimensional parametric item response theory models for dichotomous items were employed in 51 per cent of the articles. The usual unidimensional parametric item response theory models for polytomous items were employed in 21 per cent of the a…
Understanding the Power Interactions between Villages and the State
Chinese villages have been historically regarded as autonomous areas without officials from the state. Since the founding of modern China in 1949, the two forces of state and villages that once co-existed and had no influence on each other have produced ever closer relations or even conflicts. The state power has accelerated the process of infiltration into villages in the last decade. Through the observation and research of sand mining in Beicun…
