经资料搜集与野外调研,对云南三江造山带西部重要断裂的位置、特征及南北连接,形成了一些新的认识.即：①怒江断裂在滇西北为高黎贡山变质基底杂岩与丙中洛地块、滇西南为潞西断块与保山地块的边界断裂,属三级构造单元的边界断裂;②班公错-东巧断裂进入云南后,北段、中段与位于高黎贡山主峰的向东倾斜的高黎贡山逆冲推覆断裂相连接,南段称为龙陵-瑞丽断裂;③高黎贡山断裂、龙陵-瑞丽断裂为腾冲造山带与三江造山带的边界断裂,属一级构造单元的边界断裂;④昌宁-孟连结合带东西两侧的双江-竹塘断裂、沧源断裂北延至滇西北后,分别与位于碧罗雪山西坡的福贡断裂、捧当断裂相连接;⑤迪麻洛-昌宁-孟连结合带为二级构造单元,东西两侧的二级构造单元分别为崇山-临沧地块、丙中洛-保山陆块.云南三江造山带西部划分为2个二级构造单元、7个三级构造单元.     

山东半岛海域成矿区带划分浅析

山东半岛海域成矿区带划分以往研究程度较低。该文利用海域重磁资料,在研究区梳理了渤海和黄海的重磁异常特征,渤海和北黄海呈负布格重力异常,南黄海北部与之相反;渤海为正磁异常,黄海与之相反。以重磁异常为基础,基于陆域构造单元划分,对海域构造单元划分至Ⅲ级10个构造单元,海域构造单元多为陆域向海域的延伸,仅渤中坳陷和北黄海盆地为独立的海域构造单元。参照陆域成矿区带划分,以构造单元边界为界线,海域成矿区带划分至Ⅳ级6个成矿区,各成矿区特征不同,坳陷构造单元内成矿区富集油气矿产,隆起构造单元内成矿区表现为埕宁隆起富集煤矿,胶北隆起富集金、菱镁矿、煤、灰岩矿,千里隆起富集岩金、蛇纹岩、石棉、花岗石矿。     

Mapping crime harm and priority locations in New Zealand: A comparison of spatial analysis methods

Despite progress being advanced with spatial approaches to crime and crime control, the geography of crime harm has to date received little attention. The recent development of “Crime Harm Indices”, which weight crimes by an estimate of the relative harm they cause, offers an opportunity to improve on volume based spatial analysis approaches to identify where crime harm concentrates.This study aims to address this issue via the use of a Crime Harm Index (CHI) developed for New Zealand. By contrast to localized ‘harm-spotting’ analysis, we apply a census unit based approach to identify, at a macro level, the neighborhoods and wider communities suffering the highest crime harm in New Zealand. This approach enables harm to be viewed not only as a total Index but as a rate controlled for population and allows for the identification of census based sociodemographic factors which predict harm. Specifically, this paper compares the CHI with the New Zealand Priority Locations Index (PLI), an existing census unit based crime analysis tool which combines crime and demographic variables to identify communities vulnerable to crime and disorder issues.In this study CHI and PLI scores were calculated for Census Area Units (normally containing 3000–5000 population) across New Zealand. Bivariate correlations and a general linear model were used to determine the relationships between the CHI and PLI and additional population related variables. The CHI and PLI were weakly correlated, with population size and urban/rural categorization also accounting for CHI variance. Mapping techniques are used to illustrate outlier locations where the CHI and PLI differ widely and to identify location features which may assist in explaining CHI/PLI differences.This work exemplifies a novel geographic approach to the problem of crime harm with implications for resource allocation at national through to local levels. Wider implications for the theory and practice of crime and crime harm control are discussed, along with limitations of the study and areas for further research.

The modifiable areal unit problem in hedonic house-price models

When geographically aggregated data are included in hedonic models, the resulting coefficients are biased by the spatial scale and spatial configuration of variable measurement. We explore the effects of this modifiable areal unit problem (MAUP) within the context of hedonic price models with an individual-level dependent variable. Specifically, we developed standard and spatial hedonic regression models in order to examine the effects of the MAUP on model fit and coefficient estimates. Our empirical analysis documents several significant scale and zoning effects in the hedonic modeling framework. First, neighborhood characteristics are clearly important in efforts to improve model fit—and they are more significant contributors in the standard model than in the spatial hedonic model. For aggregation scale, the model fit change of the standard model is relatively large, whereas the change is more modest for spatial models. The patterns of change in model fit for standard and spatial hedonic models clearly diverge from one another, implying the existence of a scale level showing a maximum functional range of the submarket on which scale dependencies are expected to have an impact. Regarding the zoning effect, the model fits for both standard and spatial hedonic models vary according to the submarket systems.

Full scale decay test of a tanker: field data and theoretical analysis

This paper presents results from a full scale decay test made with a tanker in a relatively protected area in the Brazilian coast. In at least two tests the environmental loads (wind, waves and current) were very small and the time history of the surge motion was well behaved, making it possible to check some proposed models for the damping in the hull and mooring lines. Field data seem to confirm that the damping is indeed of the fluid viscosity type and the theoretical models are able to recover roughly 75% of the observed damping, the energy dissipation in the mooring lines being, by far, the major contribution. The remaining 25% are likely due to non modeled effects, such as the environment influence, which although small and not measured certainly exists, and to the friction between the mooring lines and the seabed.
