一种一维距离像的识别算法

随着高分辨率雷达的发展,一维距离像识别已成为雷达目标识别的重要方法之一.为了消除一维距离像的平移,将一维距离像变换到频域,提取其频谱信息作为识别特征,并依据Fisher判据,将高维特征空间数据降到一维空间,提高了算法的实时性.仿真结果表明这是一种方便有效的识别方法.

Green decisions: demographics and consumer understanding of environmental labels

This research examined the demographic profiles of Australian green consumers in relation to their satisfaction of environmental labelling. It examined consumers’ understanding of labelling and empirically investigated the association of demographic profile of consumers with their attitudes towards such labels. The results indicated that some of the demographic variables were significant, which is largely consistent with earlier findings by other researchers in this area. Label dissatisfaction was higher in the older and middle age respondents. However, some respondents disagreed that labels were accurate while commenting that labels were easy to understand. The key issue arising from the findings is that in order to provide perception of accuracy in labels, it is an option to use Type I or Type III labelling on products. These labels are, arguably, more credible because they are endorsed by third party labelling experts. This would come at a cost and for green products that use third party labelling, they will also have to bear in mind to keep the prices competitive.

国际资本流动对我国就业影响的均衡分析

文章通过建立一个劳动力市场与资本市场的均衡模型,对国际资本不流动与国际资本不完全自由流动两种情况下的分析表明,国际资本流动加剧了国内劳动力市场的就业风险,并且国际资本流动对就业水平影响与本国资本市场的开放度有关,增加开放度有利于提高本国的就业水平.我国应在采取有效措施减小国内劳动者就业波动的同时,逐渐提高资本市场的开放度.     

全球化进程中世界就业若干特征分析

随着经济全球化的深度推进,世界就业呈现出一系列规律性特征。主要表现在就业方式、就业结构以及劳资关系的变革上。正确认识全球化进程中劳动就业的规律性特征,对于制定正确的对外开放以及就业战略具有重要的意义。     

浅析现金流量信息与会计收益信息

现金流量信息由于本身的客观性、可靠性,能够弥补传统会计收益评价指标的不足,提供更有价值更为相关的信息,直接反映企业的偿债能力、获利能力、财务弹性,进而判断企业的财务状况,评估企业经营绩效。但现金流量信息并不是万能的,传统的会计收益信息也有其可取之处。在动态中把握现金流量信息与会计收益信息的结合才是企业经营业绩评价指标的正确选择。     

Comparing Big Givers and Small Givers: Financial Correlates of Corporate Philanthropy

In a departure from the traditional studies of corporate philanthropy that focus on board composition, advertising, and social networks, the authors investigate the financial correlates of corporate philanthropy. The research design controls for firm size and industry while observing firms from a variety of industries. The sample contains matched pairs of generous and less generous corporate givers. The authors find, as hypothesized, a positive relationship between a firm's cash resources available and cash donations, but no significant relationship between corporate philanthropy and firm financial performance, regardless of whether corporate philanthropy is measured as cash payouts or the aggregate contributions that charities actually receive, and regardless of whether financial performance is gauged using accounting measures or market measures. Whereas the link between available resources and corporate philanthropy is well accepted in the literature on corporate social responsibility, it has been rarely tested and never so definitively found as in this research.
