An urban eco-environmental sensitive areas assessment method based on variable weights combination
When assessing urban eco-environmental sensitive areas (Urban Eco-ESAs) by multi-criteria evaluation method, the widely used weighted linear combination method may inevitably lead to some factors of high sensitive value being neutralized by other factors of low sensitive value, resulting in the neglect of some eco-sensitive areas as a consequence, while on the other hand, Boolean OR combination method, which give a result of high sensitive value as long as any factor has the value of high sensitivity and thus ignore the mutual compensation mechanism among ecological factors, can lead to excessively wide ranges of the eco-sensitive areas. To overcome the defects of these two methods, the authors propose an Urban Eco-ESAs synthesized assessment method giving finely controlled priority to bottleneck factors, and relative model based on selective local encouraging variable weights combination. The method is able to increase the weights of some eco-bottleneck factors on the basis of a weight-changing function in synthesizing multiple factor assessments as long as their assessment values break the bottleneck threshold values, which can guarantee the eco-sensitive areas identified by bottleneck factors being embodied in the final result, while also retain the compensation effect of multiple ecological factors, which makes the results of the assessment more reasonable. In order to deliver this empirical research, Taogang Town in China, which is adjacent to Net lake wetland nature reserve area, has been used as an example to confirm the validity of the method and the model
The Relationship Between Political Skill And Employee Voice Behavior From An Impression Management Perspective
This research focused on the self-serving motivation of voice behavior from an impression management perspective, different from the previous studies on the altruistic motivation. The purpose of this study was to construct a multilevel theoretical model that proposed how political skill operates to exercise effects on employee voice behavior in the context of organizational politics climate from an impression management perspective. We hypothesized the positive relationship between political skill and employee voice behavior, and the mediating role of impression-management motives, and then examined the cross-level effects of organizational politics climate on the individual-level employee voice phenomenon. An evaluation of research limitations, suggestions for future research, contributions to the literature and practical implications were discussed finally
Poly[[(μ2-2-amino-4,5-dimethybenzenesulfonato-κ2 N:O)(μ2-2-methylpyrazine-κ2 N:N′)silver(I)] monohydrate]
In the title compound, {[Ag(C8H10NO3S)(C7H6N2)]·H2O}n, each AgI cation is four-coordinated by three N atoms from two different 2-methylpyrazine ligands and one –NH2 group of a 2-amino-4,5-dimethybenzenesulfonate ligand, and by one sulfonate O atom, in a distorted tetrahedral coordination geometry. The AgI centres are bridged by both types of ligands, forming a two-dimensional network. N—H⋯O hydrogen bonds and O⋯O interactions complete the structure

The cis-N4O2 donor set defines a distorted octahedral geometry. In the crystal structure, the complex and water molecules are linked by O—H⋯O hydrogen bonds
TM-NET: Deep Generative Networks for Textured Meshes
We introduce TM-NET, a novel deep generative model for synthesizing textured
meshes in a part-aware manner. Once trained, the network can generate novel
textured meshes from scratch or predict textures for a given 3D mesh, without
image guidance. Plausible and diverse textures can be generated for the same
mesh part, while texture compatibility between parts in the same shape is
achieved via conditional generation. Specifically, our method produces texture
maps for individual shape parts, each as a deformable box, leading to a natural
UV map with minimal distortion. The network separately embeds part geometry
(via a PartVAE) and part texture (via a TextureVAE) into their respective
latent spaces, so as to facilitate learning texture probability distributions
conditioned on geometry. We introduce a conditional autoregressive model for
texture generation, which can be conditioned on both part geometry and textures
already generated for other parts to achieve texture compatibility. To produce
high-frequency texture details, our TextureVAE operates in a high-dimensional
latent space via dictionary-based vector quantization. We also exploit
transparencies in the texture as an effective means to model complex shape
structures including topological details. Extensive experiments demonstrate the
plausibility, quality, and diversity of the textures and geometries generated
by our network, while avoiding inconsistency issues that are common to novel
view synthesis methods
