In Eastern Dhaka, perennial flood remains a constant threat to people and livelihoods. Learning from the micro-level experiences of the poor in the peri-urban areas of Dhaka provides insights on the intersections between physical vulnerability, flood response strategies, and adaptive capacity. Through a convergent mixed method, this study examines the physical vulnerability of residential buildings, flood damages, and local physical responses in three neighborhoods of Eastern Dhaka. Results show that the level of damage to buildings is the most important predictor of physical vulnerability to floods. Buildings that are older than 20 years old and built with natural materials are likely to experience high flood damages compared to buildings that are less than 10 years and constructed with durable materials. The study concludes that in addition to socio-economic interventions, a targeted and people-centered flood management regime that pays attention to age, material composition, and structural quality of houses is necessary to build residents’ adaptive capacities and long-term resilience to flooding. This study contributes to the emerging work on grassroots responses to flood vulnerabilities with practical insights for urban planners and disaster management professionals on particular interventions needed to improve the performance of local responses to flood risks and vulnerabilities.

This paper analysed socio-spatial changes in old urban neighbourhoods (Danwei compounds) in Chinese cities as a result of two major national level reforms: the Reform and Opening Up and the Urban Housing reform in 1978 and 1997, respectively. Existing research indicates fundamental changes have taken place in the political, economic and social aspects of Danwei compounds. However, there is a paucity of research on micro-level changes. To understand how these reforms have affected the social-spatial schema of Danwei Compounds, the study utilised mapping, key person interviews and field observation in AMS compound, Hefei city of Anhui province. This paper compared the AMS Danwei Compound before and after the reforms in terms of public spaces, building features and compound management. The study found that the AMS Danwei Compound has experienced a significant reduction in public space, an increase in building density and a reconfiguration of compound management actors. The study suggests the need for local planning authorities and government to pay attention to planning and design of the old city core by emphasising improvement in public spaces, attention to compact design principles for urban neighbourhood planning, and establishment of local community management body.

Danwei compounds have experienced a steady decline since the 1997 Urban Housing System Reform. Existing research suggests that Danwei compounds, which were characteristically walled neighbourhoods of work and residence, have experienced socio-spatial changes in social structure, community management and spatial form. However, there is limited understanding of its current spatial function and relation to the city. This study analysed the spatial distribution of Danwei compounds, their spatial features and accessibility to selected public facilities in comparison with non-Danwei residential sites in the old town of Hefei city. ArcGIS was used to analyse building density, plot ratio of the residential sites and their accessibility to public facilities. Further quantitative analysis was done using binary logistic regression and descriptive statistics to identify spatial features of the residential sites. The results show that even though the urban land reforms have led to a steady rise in non-Danwei residential sites, Danwei compounds predominate the urban spatial structure. Comparatively, Danwei compounds have lower plot ratios with higher levels of accessibility to commercial centres and hospitals but poor accessibility to schools. The paper suggests the need for local planning officials to support the revitalisation of old residential compounds through integrated and community-centred spatial planning.

No previous reports on lymph-node metastasis (LNM) from superficial squamous cell carcinoma of the esophagus have proposed definite criteria for additional treatment after endoscopic mucosal resection (EMR). We investigated the association between histopathological factors and LNM in 464 consecutive patients with superficial squamous cell carcinoma of the esophagus who had undergone a radical esophagectomy with lymph-node dissection (14 ‘M1' lesions: intraepithelial tumors, 36 ‘M2' lesions: tumors invading the lamina propria, 50 ‘M3' lesions: tumors in contact with or invading the muscularis mucosa, 32 ‘SM1' lesions: tumors invading the most superficial 1/3 of the submucosa and 332 ‘SM2/3' lesions: tumors invading deeper than SM1 level). Histopathological factors including invasion depth, size, lymphatic invasion (LY), venous invasion, tumor differentiation, growth pattern, degree of nuclear atypia and histological grade were assessed for their association with LNM in 82 M3 or SM1 lesions to determine which patients need additional treatment after EMR. LNM was found in 0.0, 5.6, 18.0, 53.1 and 53.9% of the M1, M2, M3, SM1 and SM2/3 lesions, respectively. A univariate analysis showed that each of the following histopathological factors had a significant influence on LNM: invasion depth (M3 vs SM1), LY, venous invasion and histological grade. Invasion depth and LY were significantly associated with LNM in a multivariate analysis. Four out of 38 patients (10.3%) with M3 lesions without LY had LNM, whereas five out of 12 patients (41.7%) with M3 lesions and LY had LNM. Only patients with M1/2 lesions are good candidates for EMR. Invading the muscularis mucosa (M3) is a high-risk condition for LNM the same as submucosal invasion, but M3 lesions without LY can be followed up after EMR without any additional treatment.
