Habitat use and activity patterns of urban-dwelling javelina

In Arizona, conflicts between homeowners and urban-dwelling javelina (Tayassu tajacu) continued to increase. Human-javelina conflicts often occurred when javelina responded to urban attractants and destroyed ornamental landscapes, injured pets, and frightened homeowners. This prompted initiation of a study during 1992–93 to develop recommendations to alleviate these conflicts. We captured, radio-collared, and located eight javelina from six herds to determine home ranges, habitat use, and activity patterns in Prescott, Arizona. Urban-dwelling javelina adjusted their home ranges, habitat use, and activity patterns to best use human-provided urban food, water, and cover resources. The most conspicuous of these adjustments was the increased nocturnal activity of urban-dwelling javelina to avoid human disturbances. Undeveloped land within or adjacent to Prescott provided javelina with daytime bedding areas and nighttime travel corridors. We determined that this issue was more a people problem than it was a javelina problem. Thus, strategies to resolve the conflicts must target homeowners.     

Application of Multivariate Analysis to Increase the Yield of Dry Cell Batteries

In an organization, the manufacturing process of a dry cell battery was suffering from the problem of frequent stoppages in the assembly line. The complete battery manufacturing operation is highly automated and mechanized. It was suspected that excessive variation in overall height of bobbin was the major reason for such stoppages. The bobbin, the inside part of a dry cell battery acting as cathode, is formed by the battery extrusion process. A planned experiment was carried out on the extrusion process that identified the setting of extrusion machines and the amount of water content in the cathode mixture as the parameters causing variation in the bobbin characteristics. The problem of frequent stoppages was eliminated when appropriate action was taken on these two parameters. Finally, multivariate and univariate control schemes were developed for online control of the bobbin characteristics.     

居延汉简中的统括性范围副词

居延汉简为屯戍记录,簿籍类文书占有很大的比重;与材料的性质相适应,居延汉简出现了很多统括性范围副词。这类副词共有20个,有的是承袭先秦汉语而来的,有的是汉代新产生的;其中"往往、大凡、最凡、与此、并"等统括性范围副词的用法较有特点。     

行政公诉的法理与制度建构——一个法律监督的视角

我国行政公诉不同于西方国家行政公诉的特点,我国行政公诉既是一种公力救济,又具有典型的监督属性,它始终以公权力监督为贯穿主线,体现为对行政权的直接监督、有限监督.从公共利益优先权和公力救济有限性的角度界定行政公诉的范围,将督促行政主体履行职责作为提起行政公诉的前置程序,以节省诉讼成本,提高监督效率.基于检察机关拥有特别的公权力,检察监督具有明显的司法性、专门性、专业性,以及为了防止行政公诉的恣意,诉讼中应当以检察机关负举证责任为原则,行政机关仅对其控制的行政信息情报、规范性文件以及公害案件涉及的高度专业性、技术性问题负责举证.

3D object recognition: Representation and matching

Three-dimensional object recognition entails a number of fundamental problems in computer vision: representation of a 3D object, identification of the object from its image, estimation of its position and orientation, and registration of multiple views of the object for automatic model construction. This paper surveys three of those topics, namely representation, matching, and pose estimation. It also presents an overview of the free-form surface matching problem, and describes COSMOS, our framework for representing and recognizing free-form objects. The COSMOS system recognizes arbitrarily curved 3D rigid objects from a single view using dense surface data. We present both the theoretical aspects and the experimental results of a prototype recognition system based on COSMOS.     

Distribution of the coates-diggle test statistic in case of replicated observations

A closed form expression for the distribution of a test statistic for comparing the spectral densities of stationary processes is given. This test statistic was introduced by COATES and DIGGLE ( 1986 ) for the unreplicated case and has been extended to the case of replicated observations by POTSCHER and RESCHENHOFER ( 1988 ). A simple method for computing approximate critical values in case of large numbers of replications is also provided. As a by-product an explicit expression for the distribution function of the range of independent variates each distributed as the logarithm of an F-variate i.e up to a factor of 2 each followin Fishers z-distriution is obtained     

Exponential family distribution with unknown truncation parameter: two sample problem

The uniformly most powerful unbiased tests are formulated for two sample problem of a given continuous distribution belonging to the exponential family with unknown scale and truncation parameters. The two-parameter exponential and Paretc distributions are considered in examples.     

Critical point and power calculations for the studentized range test for generally correlated means

The studentized range test is a widely applied statistical procedure to compare several normal means within the analysis of variance. However, up to now no general methodology is available to perform the all-pair comparisons precisely, such as the computation of p-values or quantiles in the simple unbalanced one-way layout. Instead, a variety of approximations have been proposed in the past. This article focuses on exact computations of simultaneous confidence intervals and exact sample size determinations for all-pair comparisons in the analysis of variance involving arbitrary variance-covariance matrices. General power expressions in closed form are developed and numerical issues concerning the arising multivariate central and noncentral t-distributions are discussed. An application to the usual fixed effects analysis of covariance illustrates the use of the obtained results.     

合并财务报表与母公司财务报表双重信息披露研究综述

在会计准则国际趋同的大背景下,各国(或地区)的定期财务报告披露却遵循着各不相同的披露制度.随着经济的发展,合并财务报表已逐渐取代母公司财务报表,成为投资者、公司管理层和监管者关注的重点.制度安排上的多样性凸显了各国经济社会环境对会计的影响,同时也引发了各国(或地区)对现行财务报告披露制度安排的思考.在对国内外现有相关研究进行分析和总结的基础上,通过对合并财务报表与母公司财务报表之间差异的比较研究、双重披露制下合并财务报袁与母公司财务报表的有用性研究、财务报告目标与财务报告披露制度等三个方面的探讨,发现合并财务报表与母公司财务报表双重信息披露的研究,仍有待于从报告主体多重化的角度对现行财务报告目标进行改进,对合并财务报表与母公司财务报表之间的分工与协作进行更广泛的研究,以提高双重信息披露整体有用性.
