岩石边坡工程块体系统稳定性预测、监测与控制

根据工程地质的岩体结构控制观点及“突破”观点，岩石边坡工程的稳定性往往由其中的块体分布及其稳定状态所控制，因此，及时确定与实时控制这些块体系统的稳定性就十分重要。为此，以某大型岩石高边坡为例，在分析该高边坡的工程地质条件，尤其是结构面分布特征基础上，首先，采用块体理论分析了该复杂岩石边坡工程块体系统的分布规律，找出了控制该大型边坡稳定性的关键块体的位置、规模及开挖后的稳定性系数，并据此指导优化岩石边坡稳定性的监测布置与加固控制；其次，根据监测信息对块体系统加固前后的受力及稳定性动态进行了分析。

Participation in a decentralised housing allowance programme in a transition economy

When Russia's housing allowance programme, the country's first means‐tested programme, was introduced in 1994, it was truly innovative. However, there were difficulties from the start, many arising from the division of authority for setting programme parameters among different levels of government and the potential for variation in the treatment of similar households in different cities. In 1996, the programme's original simple basis for benefit determination was seriously impaired by the introduction of different principles for very low‐income households. Moreover, local governments have exhibited a willingness to vary benefits from year‐to‐year, depending on political and budgetary considerations. The analysis presented here documents the impact of these variations on participation rates in a sample of Russian cities. Large inequities are obviously present in the treatment of similar households from city to city. Indeed, it is questionable whether the programme as currently configured is fulfilling the social safety net function envisioned for it in the original legislation.

Venting a smoky fire in a hotel stairway

A fire started within a hotel staircase which smoke-logged the stairway. Smoke leaked on to adjoining lobbies which formed part of the escape routes for upper floor guests rendering them useless as a means of escape. Whilst the majority of guests were rescued from their bedroom windows by the fire brigade, one guest was overcome by smoke within the top floor lobby in attempting to escape. By calculating mass flow rates it has been possible to explain the observed movement of smoke and to demonstrate that with the venting of the stairway, there would have been very much less smoke logging of the lobbies with a resultant life and property saving.     

Settlement in Transition: a Transformation of a Village into a Small Town in Western Sudan

UN-Habitat projects Sub-Saharan Africa’s global share of the urban population to increase from 11.3% in 2010 to 20.2% by 2050. Yet little is documented about the underlying urbanization processes, particularly of emergence of small towns. This article uses household interviews, focus groups, observation, and secondary data to examine the spontaneous transformation of a western Sudanese village, Shubbola, into a small town. We use changes in building construction approach, materials, and style as an indicator of development and provide rare documentation of the process, the main actors, choices taken, timescales, and outcomes of the rapid urbanization of Shubbola between 2006 and 2013. Housing transformation was variable but involved a gradual process of replacing traditional non-durable building materials (wood and straw) with modern durable ones (sun- or fire-cured bricks, cement blocks, and metal roofs). Unlike traditional top-down models of urbanization generally driven by government investment, Shubbola epitomizes an organic, bottom-up process dependent on self-reliance and agriculture development fueled by remittances from urban-based relatives. While many small towns with similar origins fail to do so, Shubbola already provided important urban services to its inhabitants and surrounding rural areas. The study enhances understanding of small towns and underlying urbanization processes and their contribution to often neglected bottom-up, low-cost processes that do not fit traditional top-down models. It also contributes to literature and policy on sustainable cities and their role in sustainable development as encapsulated in UN Sustainable Development Goal 11. The study contributes to understanding the processes and implications of rapid urbanization in the Sudan and Africa and other world regions.
