陕西洋县朱鹮河流栖息地生境修复 研究

河流是朱鹮重要栖息地之一,在朱鹮逐渐转移至低 海拔区域生存的趋势下,提高河流栖息地生境质量是当前朱鹮 保护的重要内容之一。利用数据收集、现场调研、ArcGIS等 分析方法对近年来河流栖息地生态变化过程进行分析,分别从 栖息地适宜性、景观格局指数及生境质量3个方面探讨朱鹮河 流栖息地质量的状况,从中找出朱鹮河流栖息地生境的具体问 题。从不同河流生境尺度,探讨朱鹮河流栖息地的修复方法。     

湖滨带农村常住居民支浜生态修复需求与支付意愿——以太湖竺山湾地区为例

提升居民参与水平,加快支浜生态修复是改善湖滨带缓冲功能和太湖水环境治理的重要需求。对太湖竺山湾地区204户农村常住居民的调查发现:1)感觉2014年支浜水质比2004年"非常差"或"非常好"的居民比例大幅降低,表明太湖湖滨带水质恶化得到初步控制但总体改善不明显;2)80.88%的湖滨带农村常住居民对支浜生态修复工程具有支付意愿,其中62.4%愿意一次性支付,户均支付意愿163元,27.9%愿意按年支付,户均支付意愿136元/年,9.7%愿意按月支付,户均支付意愿24元/月;3)Logistic分析表明,受教育水平对湖滨带农村常住居民支浜生态修复工程支付意愿具有显著正向影响;4)在经济相对发达的太湖流域,农村水环境治理社会基础较好,生态建设资金有保障、工程运行监管等政策设计中应重视并充分发挥当地常住居民的作用。     

Projected Country Image: An Investigation of Provinces/Cities’ Logos

Place image studies can be divided into two broad categories: perceived image and projected image. The former category has been receiving a lot of attention for more than four decades, while projected place image has not received an adequate consideration. In this study, the projected image of a country (i.e. Vietnam) is investigated using new image representatives: provinces/cities’ logos. Both the cognitive and affective aspects of the image are examined, and the interpretable pictorial attributes are compared with the intentional textual projections. The findings provide practical implications for the projection of the country's image in the future. It also introduces a theoretical contribution to enrich the projected place image literature.     

基于投影寻踪分类模型的中国区域创新能力评价研究

区域创新能力评价对于政府决策和企业投资环境选择具有重要的实践意义.本文基于2003-2006年的全国29个省市自治区的截面数据,利用投影寻踪分类模型对我国区域创新能力进行了评价,并按综合创新能力大小,将全国分为三类地区.实证结果显示,江苏和广东是创新能力最强的两个省份,而宁夏则是创新能力最弱的地区,且陕西和海南是创新能力提升最快的两个省份,而河北和青海则是创新能力下降最快的两个地区.     

The Accounting Profession: Substantive Change and/or Image Management

The accounting profession’s image and reputation is built upon the members of the profession acting with the “highest sense of integrity” in “the public interest” (AICPA, 2003, www.aicpa.org/about). The Enron debacle initiated the latest crisis facing the profession regarding its image and reputation. The American Institute of Certified Public Accountants (AICPA) is the largest professional body representing the accounting profession and the one to which regulators have looked in establishing and upholding professional standards relating to the public practice of accounting and auditing. One of the AICPA’s responsibilities is to “promote public awareness and confidence in the integrity, objectivity, competence and professionalism of CPAs ....” (AICPA, 2003, www.aicpa.org/about). We analyze the public statements issued by the AICPA (i.e., press releases, speeches of officers, testimony, published articles) during this ethical and identity crisis beginning with the AICPA’s first public statement on the Enron debacle (AIPCA 2001) and concluding with the AICPA recognizing the need for a “new accounting culture” (Melancon 2002). In order to better understand the public discourse, we use image restoration theory (Benoit, 1995), because it provides a typology of strategies for dealing with the public face of crises. We identify the three most common strategies the AICPA employs during this period. Proposals for taking corrective action represent the most commonly employed strategy, but the analysis also indicates an attempt to evade responsibility by claiming defeasibility and to reduce the offensiveness of the situation by employing a bolstering strategy. A second analysis using DICTION, a software package useful in revealing latent dimensions in a text, indicates that early statements tend to use language related to accomplishing specific action while the later statements tend more toward general language that relates to peoples’ everyday lives. The findings raise questions as to substantive nature of the changes proposed by the AICPA, and thus, the extent to which the public interest is being served by them.     

LUCC of large opencast mines in loess area during ecological restoration： a case study of Pingshuo Mine

1. Introduction Studies on land eco-recovery and ecology re- construction emerged in1960s in the world, but it didn't begin until 1980s in China. Actually, the stud- ies on land recovery and ecological reconstruction began in China in 1990s. Many large progresses have been made in the study on the theory of eco- logical recovery of disused land in recent 10 years [1-3]. According to the characters of terrene and min- eral resources, the research areas of ecological re- covery consist of: (1) …     

基于遗传投影寻踪模型的高校人力资源管理综合评价

针对高校人力资源管理评价指标的不相容性问题,提出了高校人力资源管理综合评价的遗传投影寻踪方法。该方法可以依据样本自身的数据特性寻求最佳投影方向,利用最佳投影方向可判断各计价指标对综合评价目标的贡献大小和方向。通过最佳投影方向,与评价指标的线形投影得到投影指标值,通过这一指标来对样本进行统一评价和分类。运用该模型对3所高校人力资源管理状况进行了综合评价,得出评价等级,为高校人力资源管理提供可量化并带有预测性的科学评价方法。
