Frontier spaces of vulnerability: Regional change,urbanization, drought and fire hazard in Santarém,Pará, Brazil

Fire hazard is a mounting concern in tropical rainforests of the Brazilian Amazon and has raised awareness within the science community of the links between agricultural fire use, drought and accidental fire. As a result, fire is being addressed as a crisis event with mitigation focused on those who light fires, particularly smallholder agriculturalists. Little attention is paid to the historical and ongoing ways in which Amazon landscapes and peoples have been made more susceptible to fire. Frontier regions of the Brazilian Amazon serve a variety of functions within the larger Brazilian society, including as extractive reserves for economic development, as social safety valves to reduce population pressures, and as areas to support urban regional integration. Each of these functions has impacted frontier environments in ways that create more flammable landscapes and/or shape the vulnerability of people to fire hazard. This paper uses a case study inthe Brazilian Lower Amazon to understand how vulnerability to fire hazard develops. It argues that if fire mitigation remains centered on fire as a crisis event, an understanding of what constitutes frontier spaces of vulnerability, both in landscape and in populations, will be limited.     

The University: An Agent of Social Change?

Can universities be agents of progressive social change? How would we know if a university was acting as an agent of social change? Drawing on four case studies, I raise a number of questions to problematize our understanding of the university as an agent of social change. I outline a number of contributing factors that appear to explain successful cases. I conclude by arguing the relevancy of these cases for larger, and more traditional, sociological projects.

地力山土族生计方式与家庭经济结构

地力山是甘南藏族自治州卓尼县杓哇土族乡的一个纯土族自然村。由于特定的历史、自然和社会原因,形成了以农为主牧业为辅的传统生计方式。随着时代的变化,兼事务工成为了传统生计方式的补充。在地力山土族家庭经济过程中,生计方式支配着资源要素的投入方向,而资源要素在不同方向上的配置最终构成其家庭经济的各个形态,形态之间以及具体形态内部存在的动态性,为其进一步调整提供了内在条件。

K_2PdX_4:Cu~(2+)超超精细参量研究

利用离子簇模型,建立了四角伸长八面体中3d9体系超超精细参量的微扰公式;在理论上得到了轨道混合系数、未配对自旋密度、平均共价因子等参量的关系,并应用于K2PdX4(X=Cl,Br)中的四角[CuX4]2?中心,理论与实验比较符合。与文献[4]相比,该文在计算公式上有所简化,并且调节参量数目进一步地减少,因而具有较好的适用性。

债务融资、债务结构与公司过度投资行为——来自我国上市公司的经验证据

文章以我国A股市场上市公司为研究对象,实证研究了债务融资对过度投资行为的抑制作用.研究发现:我国上市公司普遍存在着严重的过度投资现象,债务融资及其构成特征整体上并未对公司的过度投资行为起到抑制作用.通过进一步按最终控制人性质分组检验发现,债务融资比例与银行借款在国有控股公司不但没起到抑制过度投资行为的作用,反而还恶化了公司的过度投资行为,债务融资比例与银行借款在非国有控股公司中起到了制约过度投资的作用,商业信用和长短期债务在国有与非国有控股公司中仍没起到制约公司过度投资行为的作用.     

葬礼:面对死亡的社会安排 ———城市环境下葬礼仪式浅析

通过实地观察和对殡仪馆工作人员的访谈，描绘了天津市城市内部现有的国家规范框架下葬礼仪式的具体过程以及附着在这个框架下的民间习俗的现状，试图通过对国家规范框架下的“正式”葬礼仪式及与其相对的“非正式”仪式——家庭告别仪式的程序形式的简略描述，展现在城市中普通个人的葬礼基于公共环境和家庭环境不同场景所采用的不同仪式过程。这是民间习俗对规范仪式的补充，同时也是“正式”规范对这种“非正式”实践的通融和消化。在描述现状之外，作者试图讨论蕴含在葬礼仪式中，不同死亡个体的葬礼仪式形式、规模及参与者等方面的区分所展现出的一种社会对死亡个体生前所处社会结构地位的认同，这种认同不仅反映了仪式所处社会背景的秩序和结构，也强化了这个社会的秩序和价值判断标准。     

Estimating household structure in ancient China by using historical data: a latent class analysis of partially missing patterns

Summary.  Social data often contain missing information. The problem is inevitably severe when analysing historical data. Conventionally, researchers analyse complete records only. Listwise deletion not only reduces the effective sample size but also may result in biased estimation, depending on the missingness mechanism. We analyse household types by using population registers from ancient China (618–907 AD) by comparing a simple classification, a latent class model of the complete data and a latent class model of the complete and partially missing data assuming four types of ignorable and non-ignorable missingness mechanisms. The findings show that either a frequency classification or a latent class analysis using the complete records only yielded biased estimates and incorrect conclusions in the presence of partially missing data of a non-ignorable mechanism. Although simply assuming ignorable or non-ignorable missing data produced consistently similarly higher estimates of the proportion of complex households, a specification of the relationship between the latent variable and the degree of missingness by a row effect uniform association model helped to capture the missingness mechanism better and improved the model fit.
