Residual analysis for spatial point processes (with discussion)

Summary.  We define residuals for point process models fitted to spatial point pattern data, and we propose diagnostic plots based on them. The residuals apply to any point process model that has a conditional intensity; the model may exhibit spatial heterogeneity, interpoint interaction and dependence on spatial covariates. Some existing ad hoc methods for model checking (quadrat counts, scan statistic, kernel smoothed intensity and Berman's diagnostic) are recovered as special cases. Diagnostic tools are developed systematically, by using an analogy between our spatial residuals and the usual residuals for (non-spatial) generalized linear models. The conditional intensity λ plays the role of the mean response. This makes it possible to adapt existing knowledge about model validation for generalized linear models to the spatial point process context, giving recommendations for diagnostic plots. A plot of smoothed residuals against spatial location, or against a spatial covariate, is effective in diagnosing spatial trend or co-variate effects. Q – Q -plots of the residuals are effective in diagnosing interpoint interaction.     

海水淡化装置水流特性的三维数值模拟

运用计算流体力学方法，对多级闪发式海水淡化装置第一级的流动进行了三维数值模拟，分析了闪发室内的水流特性，并将有阻流板的与无阻流板的计算结果进行了比较，数值模拟结果表明，闪发室内存在着大尺度的环流和旋涡，且主导着闪发室内的流态，对闪发效率产生重要影响；阻流板确能很大地改变整个闪发室的水流特性，但目前的阻流板设置方式对提高闪发效率是不利的．     

Bias correction for parameter estimates of spatial point process models

When a spatial point process model is fitted to spatial point pattern data using standard software, the parameter estimates are typically biased. Contrary to folklore, the bias does not reflect weaknesses of the underlying mathematical methods, but is mainly due to the effects of discretization of the spatial domain. We investigate two approaches to correcting the bias: a Newton–Raphson-type correction and Richardson extrapolation. In simulation experiments, Richardson extrapolation performs best.     

一种疏水缔合聚合物快速溶解方法研究

研究了疏水缔合聚合物（AP–P4）经过拉伸装置后的溶解时间。结果表明，拉伸装置可以缩短疏水缔合聚合物的溶解时间；拉伸装置的最佳间距为200 μm，此时疏水缔合聚合物的溶解时间为25 min。经拉伸装置处理后的疏水缔合聚合物可以在30 min 内达到溶解；提高温度可以显著改善疏水缔合聚合物的溶解效果，缩短疏水缔合聚合物的溶解时间。     

Narratives from the neighbourhood: The discursive construction of integration problems in talkback radio1

This paper examines how speakers deploy narrative devices in talking about Sudanese refugees. Particularly, we show how narrative constructions form an important basis for the advancement of accounts about integration problems into the local polity. We analyse talkback ‘phone‐in’ calls to a local Adelaide radio station that provide callers an opportunity to give accounts of events and social phenomena that concern them in their local settings. Analysis shows that speakers regularly deployed narrative constructions, first‐hand ‘witnessing’ devices that functioned to legitimate accounts as veridical versions of events, and contrast devices to explicate the moral and behavioural aberrance of Sudanese refugees. The analysis illustrates how these discursive devices function rhetorically in interaction, in ways that differentiate Sudanese refugees as problematic. Through this analysis, we contend that narrative devices precipitate and bolster socio‐political policies that have serious, negative consequences for Sudanese refugees.     

指类句的修辞性嬗变

指类句可加以改造而获得特定修辞效果,"全都……,只有……"这一句式就是一例。此类修辞效果是通过"全都……"增强语句的语义信息到极致获得反衬,继而通过"只有……"突显例外现象实现的。指类句是对一类事物属性的隐性全称量化,同时又容忍例外现象。对指类句的元语用分析表明,在元语用层次,理解指类句的认知机制、指类句理解的心理逻辑和语言使用的会话修辞逻辑使得这种改造成为可能。
