企业融资决策由于新会计准则而产生的影响因素分析

融资是企业筹集资金目前经常会运用的方式,企业融资就是指因为企业需要调整资本结构、生产经营管理、对外投资决策一系列活动希望通过金融机构和金融市场,运用适当的方式及手段获取所需资金的一种理财活动.企业获得资金转移信息的主要渠道是来自于会计领域,那么新企业会计准则制度的实施,必然有一些新的规定将对企业融资决策产生影响,此篇论文就将从这个角度探讨.     

酸沉降影响稻米品质的新发现

酸沉降影响了稻米质量和口感.酸雨时空分布从宏观上概括了稻米品质的地理分布.酸雨决定了酶活性相关金属离子的丰缺,继而影响淀粉合成关键酶的活性,最终影响淀粉合成质量.温度变化是表象,降雨pH值变化是条件,酶活性相关金属离子丰缺是根本,实质是酶活性相关金属离子或激活或抑制了支链淀粉合成关键酶的活性.提出了改善粮食作物质量的化控创新技术路线.     

南京江北核心区气候环境宜居性评价

气候环境条件是影响宜居的一个重要因素。运用多层次评价模型,从气象灾害、大气环境、人体健康及生态气象等4个层面筛选出20项指标,构建区域气候环境宜居性的评价体系,基于层次分析法(AHP)确定各指标的权重,并以南京江北核心区为例,对其宜居水平进行评价。结果表明:在青奥生态建设期间(2011—2014年),研究区的宜居水平整体呈上升趋势,属于宜居范畴,接近非常宜居的标准。这反映青奥会期间的环境整治与灾害防治工作初见成效,对江北核心区的宜居性起正效应作用。     

湿地受损遥感识别方法及其在天津滨海新区的应用

城市化进程的加快及对湿地资源的不合理开发利用造成湿地严重受损,开展湿地资源的时空变化监测对于湿地的合理开发和可持续发展具有重要作用。基于多时期土地利用数据和长时间序列的Landsat影像数据,利用马尔科夫转移矩阵和GIS空间分析法分析湿地类型受损状况,利用趋势分析法分析长时间序列和不同阶段的湿地植被、水体和土壤湿度要素受损状况,构建了湿地受损遥感识别方法,综合湿地类型和湿地要素受损状况,分析湿地受损模式,并在天津滨海新区进行案例研究。结果显示:滨海新区湿地类型受损主要分为3个时期(1980s—2000年、2000—2009年、2009—2015年),期间湿地经历了从受损到恢复的过程,1980s—2015年滨海新区湿地面积增加了41.40 km ²;1984—2015年湿地要素均呈退化趋势,植被、水体和土壤显著退化的面积分别为364.66、221.28和253.94 km ²。在不同时间段内,影响湿地面积受损的主导因素不同,3个时期滨海新区湿地受损分别是植被、水体和植被占主要地位。     

Sustainable coastal communities in the age of coastal storms: Reconceptualising coastal planning as ‘new’ naval architecture

Hurricanes devastated the Gulf coast of the USA in 2005. Hurricane Katrina, in particular, highlighted the compelling need to build more sustainable and hazard-resilient communities. Much can be learned from recovery efforts to rebuild the Gulf coast. Personal observations and interviews with planners, academics and others involved in recovery efforts inform this analysis, which focuses on New Orleans. A conceptual framework is developed and principles and operational imperatives outlined to guide action for building sustainable, hazard-resilient communities. Such communities will remain elusive unless ‘business as usual’ is confronted by a transformational process of developmental planning. Sustainable, hazard-resilient coastal communities are founded upon robust ‘critical infrastructure’ that is secured by planning and decision-making processes that enable coastal communities to build ‘layers of resilience’ to overcome ‘waves of adversity’. Planners need to take on a redefined role—as ‘new naval architects’—to design and build communities that are ‘sea-worthy’ in this age of coastal storms.

Advancing urban ecosystem governance in New York City: Shifting towards a unified perspective for conservation management

New York City’s extensive municipal park system is home to forests, wetlands, and grasslands that provide important ecological and social benefits to the city’s population. While efforts and programs exist to restore and protect these spaces, management recommendations are complex due to variable conditions in urban natural areas. To advance the management of urban natural areas, the first comprehensive ecological assessment was conducted through a collaborative effort across 4000 ha of natural areas within New York City parkland. Field and spatial data were collected and analyzed to identify the extent of forests, the types of forests, and their conditions. This approach will help guide decision-making and prioritization of natural area management at the regional level by developing unique quantitative targets for urban forests. This project serves as an example of collaboration between private and public institutions advancing the governance of urban natural areas to achieve citywide conservation and policy goals.     

Global Trend of Low-carbon Economy and China's Responses

Based on the analysis on the global economic crisis,climate change crisis and their mutual underlying reasons,the authors believe that low-carbon economy has become an inevitable choice to break through the dual crises,coordinate the economic development,and protect the global climate.The global trend of low-carbon economy finds expression in Green Recovery currently,while,in a long run,it will give rise to a new pattern of world competition in politics,economy,technology,trade and finance.The impact of the...     

Continuity,social change and Katrina

For some time, disaster researchers have looked for social change and mostly found continuity. This paper argues that shifting the focus from investigating social change to documenting continuity may enhance the understanding and planning of post‐disaster situations especially in industrialised societies like the United States. Drawing from qualitative data from post‐Katrina New Orleans, it proposes using the concept of continuity as an analytical device both to identify the axes of continuity and evaluate the likelihood and possible dimensions of social change. The analysis of long‐term recovery plans, along with field observations and interviews with evacuees, suggest that despite the well‐documented emergence of conflict in post‐Katrina New Orleans, the likelihood of social change appears limited.
