Retraction: ‘Hepatitis B Virus Infection in Preconception Period Among Women of Reproductive Age in Rural China – A Nationwide Study’ by Qiongjie Zhou, Xiaotian Li, Qiaomei Wang, Haiping Shen, Yiping Zhang, Shikun Zhang, Ganesh AcharyaThe above manuscript, published online on 15 June 2017 in Wiley Online Library (http://wileyonlinelibrary.com), has been retracted by agreement between the authors, Cande V. Ananth, the Editor‐in‐Chief of Paediatric and Perinatal Epidemiology, and John Wiley & Sons Ltd. The retraction has been made at the request of the authors since the data collected from self‐report of the HBV vaccination remains unverified, and potentially subject to errors.ReferenceZhou Q, Li X, Wang Q, Shen H, Zhang Y, Zhang S, Acharya G.

Karst landforms are characterized by high permeability, shallow soils, and steep slopes. Currently, traditional village development in karst mountainous areas tends toward homogenization, always overlooking geological features in conservation efforts. This study, focusing on all 757 traditional villages in Guizhou province, employed Geographic Information System (GIS), Geodetector, and Analytic Hierarchy Process (AHP) to develop a spatially suitable evaluation model that integrates objective driver analysis with subjective weight validation. The aim is to reveal the mechanisms by which geographic and disaster factors influence village distribution. Key findings include the following: (1) Traditional villages exhibit a dual-core clustered pattern centered on “Qiandongnan–Anshun”, with Qiandongnan having the highest concentration. (2) The selected factors—altitude (A), slope (B), aspect (C), flood sensitivity (D), and landslide sensitivity (E)—show explanatory power ranked as A > D > E > C > B. Interaction between any two factors nonlinearly enhances explanatory power. (3) Spatial suitability evaluation identified four suitability categories. Highly suitable areas are mainly in Qiandongnan, while unsuitable zones—containing only 7.66% of villages—are concentrated on the western Guizhou plateau. These results can inform conservation planning and spatial remediation across different administrative levels, providing a foundation for future development.

China’s socialist workers’ housing occupies an uncertain position between everyday residential use and potential heritage conservation. This study examines long-term modifications to Soviet-style workers’ housing in Harbin’s Village of Powers (VoP), where original collective facilities have been adapted to changing household and economic needs. Drawing on historical drawings, available evidence of early occupancy, architectural surveys of 17 buildings with comparable spatial-area data, interviews, and on-site observations, this study compares reconstructed historical usage conditions with those documented in 2020–2021. It examines spatial redistribution, modification practices, and their social consequences. Building-level comparisons show that the proportion of private space increased by an average of 6.69 percentage points in nine dormitories, compared with 0.21 percentage points in eight family apartment buildings (two-sided exact permutation test, p = 0.00045). However, the difference in total usable floor-area growth was not statistically significant. The documented cases identify improving living conditions and pursuing economic opportunities as two recurring motivations for modification, while the social consequences varied. Some interventions restricted access to collective facilities and were associated with tensions over shared-space use, whereas certain commercial spaces accommodated social interaction under specific conditions. Situated within the transformation of China’s Danwei system, these findings reveal how everyday modifications reshape the relationship between private and collective space. They provide socio-spatial evidence for heritage-sensitive regeneration that considers historical spatial characteristics, contemporary living needs, and the interests of different users. Although the quantitative analysis covers 17 buildings with comparable historical and 2020–2021 spatial-area data, the study is confined to a single purposively selected case.
