区域管制扇区复杂性指标构建及分析

运用协方差矩阵和系统聚类法对区域管制扇区复杂性指标间关系进行研究。基于对区域管制扇区结构和流量分布特征的分析,构建7个复杂性指标。以国内37个区域管制扇区数据为样本,结合可视化协方差矩阵阐明复杂性指标相关性。研究表明,区域各扇区面积相差悬殊（变异系数194.75%）,但流量在不同路径的分布均匀程度比较一致（变异系数9.02%）;扇区范围越大,往往流量在各路径上的分布越均匀（相关系数0.54~0.59）,但扇区流量反而越低（相关系数-0.06~-0.13）;以并类距离0.70为界,扇区复杂性指标分为静态和动态两类,且静态指标共性强于动态指标。

A New Random Forest Applied to Heavy Metal Risk Assessment

As soil heavy metal pollution is increasing year by year, the risk assessment of soil heavy metal pollution is gradually gaining attention. Soil heavy metal datasets are usually imbalanced datasets in which most of the samples are safe samples that are not contaminated with heavy metals. Random Forest (RF) has strong generalization ability and is not easy to overfit. In this paper, we improve the Bagging algorithm and simple voting method of RF. A W-RF algorithm based on adaptive Bagging and weighted voting is proposed to improve the classification performance of RF on imbalanced datasets. Adaptive Bagging enables trees in RF to learn information from the positive samples, and weighted voting method enables trees with superior performance to have higher voting weights. Experiments were conducted using G-mean, recall and F1-score to set weights, and the results obtained were better than RF. Risk assessment experiments were conducted using W-RF on the heavy metal dataset from agricultural fields around Wuhan. The experimental results show that the RW-RF algorithm, which use recall to calculate the classifier weights, has the best classification performance. At the end of this paper, we optimized the hyperparameters of the RW-RF algorithm by a Bayesian optimization algorithm. We use G-mean as the objective function to obtain the optimal hyperparameter combination within the number of iterations.     

GENETIC ALGORITHMS: A Search Technique Applied to Behavior Analysis

Abstract

Genetic algorithms are powerful generalized search techniques. This paper shows that genetic algorithms can solve a difficult class of problems in general systems theory quickly and efficiently. Genetic algorithms appear to be ideally suited to solving the combinatorially complex problem of behavior analysis. The search space of behavior analysis experiences exponential growth as a function of the number of variables. The genetic algorithm converges after considering a small percentage of these potential solutions. The number of solutions that need to be examined by the genetic algorithm seems to be a polynomial function of the number of variables and, in fact, the growth appears to be linear

Corporate E-Cruiting: The Construction of Work in Fortune 500 Recruiting Web Sites

Corporate recruitment efforts have evolved from traditional newspaper want ads to highly sophisticated, rhetorically powerful recruiting Web sites or "career sites." This e-cruiting phenomenon offers a unique opportunity not only to examine organizations' persuasive attempts to recruit potential applicants online, but also to uncover contemporary corporate representations of the meaning(s) of work. Using a random sample of recruitment Web sites of Fortune 500 companies, we employ content analysis and rhetorical criticism to catalogue content types, identify persuasive structure, and analyze rhetorical themes in representations of work. The investigation reveals that career sites are not merely places to post job openings, but reflect corporations' attempt to sell a glorified image of work, one which positions workers as powerful actors and employers as kind benefactors. In view of current reports on working conditions, we argue these glorified representations reflect a rhetoric of idealization and discuss potential consequences of such a strategy.
