Effects of landforms on the erosion rate in a small watershed by the Cs tracing method

It's very important to analyze and evaluate quantitatively the effects of landforms on soil erosion for the prevention and treatment of soil loss in a small watershed. The objective of this study was to evaluate the effects of landform factors on erosion rate by the ¹³⁷Cs tracing method in a small watershed in the Purple Hilly Area of China. The erosion rates under different slope lengths, slope gradients and slope aspects were estimated in Xiangshuitan watershed in the Purple Hilly Area in Sichuan Basin by the ¹³⁷Cs tracing method. The results showed that the erosion rate decreased exponentially with downslope distance, and it increased with increasing slope gradient during the scope of 5°-16°. The slope aspect had great impact on the erosion rate, and the hillside on the sunny slope had larger erosion rate than that on the shady slope, particularly for the farmland.

Conceptualizing and incorporating social sustainability in the business world

One of the most important challenges faced by business managers today is the integration of sustainability into their core functions. The contemporary enterprise is forced to leap forward from the mere adoption of green practices toward rethinking, redesigning, and redeveloping business practices in a more sustainable way. Most of the initiatives in this attempt have so far emphasized primarily the economic and environmental aspects of sustainable development and overlooked the social dimension of sustainability. As more organizations commit to sustainability, there is an increasing concern to incorporate social sustainability throughout their business operations. To conceptualize and integrate the notion, some organizations use preexisting indicators to demonstrate the value and impact of sustainability, while others look beyond the measurement of impacts by constructing their own system of indicators. This paper draws on a comprehensive literature review to determine a broadly acceptable framework of social sustainability indicators to be conceptualized and integrated into the business world. Findings suggest that economic and environmental sustainability can be driven together with core social factors including fairness and equality, poverty, health, education, delinquencies, demography, culture, and employee engagement within an organization. These results offer insight into the emerging phenomenon of formulating sustainable business strategies for organizations based on social indicators to attain the ultimate sustainable outcomes. This study is among the first to identify social sustainability indicators from societal and corporate perspectives. It offers a comprehensive social sustainability framework that may be adopted by organizations in the business world.     

渤海无机氮水质稳定性预测

近年来,渤海水环境污染日趋严重,无机氮是主要的污染因子,对无机氮水质稳定性的预测可为渤海水质站位优化和污染治理提供依据。本文以2002~2013年夏季无机氮趋势性监测数据为基础,用IDW和回归分析方法对无机氮各类水质发生概率进行预测,并计算2014~2016年无机氮水质稳定性概率,将渤海无机氮水质稳定性划分为高稳定性区域、中稳定性区域和低稳定性区域,为渤海无机氮监测站位布设和污染控制提供依据。

The Tasman Spirit oil spill: implications for regulatory change in Pakistan

An oil spill in July 2003 from the tanker Tasman Spirit attracted considerable public and media attention in Pakistan. This paper focuses on the experience of a developing country such as Pakistan in dealing with a major oil spill and its impact on bringing about change in the national regulatory framework. A major outcome has been the ratification of the International Convention on Civil Liability for Oil Pollution Damage 1992, which came into force in March 2006 in Pakistan. The convention provides a compensation mechanism for victims incurring oil pollution damages from maritime casualties involving oil laden ships. Several additional changes are still required to improve the country's ability to cope with marine oil spills. These include the development of a comprehensive domestic regulatory framework, implementation of an effective contingency plan, and capacity building of all relevant agencies.
