景观公正的研究进展与多维评价方法 探究

随着社会发展,城镇化进入转型时期,关于城市发展中社会公正的讨论越来越多,从景观视角来保障社会公正是风景园林师当下的责任。景观公正是指对于绿地资源的合理分配、使用、管理和运营,不论使用者的社会地位高低,让他们平等地享有景观权利与担负景观义务,其核心是景观层面上的平等正义。梳理了国内外景观公正的发展与研究进展,厘清景观公正的定义与内涵,总结景观公正的分配公正、过程公正和互动公正3个维度的应用场景与评价方法,对未来景观公正的建设内容提出了展望和建议。

Stochastic model for BOD and DO in streams when the velocity is random and distance‐dependent

The stochastic model studied in this paper is a random differential equation of the form X(t) = A(t) X(t) = Y(t), t ≥ 0, with initial conditions X₀ = X(0). X(t) is a vector with biochemical oxygen demand (BOD) and dissolved oxygen (DO) at a distance t downstream from the pollution source for components. The velocity of the stream is incorporated into the vector A(t) and is random and distance dependent. The inhomogeneous term Y(t) and the initial conditions are random vectors. Therefore, this model contains random initial conditions, random coefficients and random inhomogeneous terms. Simulated trajectories of the BOD and DO are computed.     

On the malleability of ideology: Motivated construals of color blindness.

The authors propose that the content of certain sociopolitical ideologies can be shaped by individuals in ways that satisfy their social motivations. This notion was tested in the context of color-blind ideology. Color blindness, when construed as a principle of distributive justice, is an egalitarian stance concerned with reducing discrepancies between groups' outcomes; as a principle of procedural justice, however, color blindness can function as a legitimizing ideology that entrenches existing inequalities. In Study 1, White people high in antiegalitarian sentiment were found to shift their construal of color blindness from a distributive to a procedural principle when exposed to intergroup threat. In Studies 2, 3A, and 3B, the authors used manipulations and a measure of threat to show that antiegalitarian White people endorse color blindness to legitimize the racial status quo. In Study 3B, participants' endorsement of color-blind ideology was mediated by increases in their preference for equal treatment (i.e., procedural justice) as a response to threat. In the Discussion section, the authors examine implications of the present perspective for understanding the manner in which individuals compete over the meaning of crucial ideologies.

往复式单螺杆销钉挤出机典型螺纹元件混合性能研究

使用Polyflow有限元软件对往复式单螺杆销钉挤出机（简称Buss机）的三类典型螺纹元件内物料流动和混合过程进行了数值模拟。流场分析中使用了网格重叠技术。在得到流场速度分布后,基于粒子轨迹跟踪技术计算了物料微元在螺纹元件内的流动轨迹,并分析了Buss机螺纹元件内物料的动态混合过程。以分布混合指数和分隔比例为指标定量地对比了螺纹元件的分布和分散混合性能,在此基础上分析了加工条件、物料特性及销钉布置对Buss机混合性能的影响。数值模拟结果与前人研究有较好的吻合性。

The dynamics of Swedish national and regional house price movement

In this study, the recent persistent growth of regional house price pattern in Sweden is explained by the fundamental variables and the regional distributive perspective on household income and wealth are indicated to be important to understand the different level and development of regional housing market. We also discuss the long running relationship between house prices and migration flows and highlight its critical role on house price analyses.
