A New Mathematical Approach in Environmental and Life Sciences: Gene–Environment Networks and Their Dynamics

An important research area in life sciences is devoted to modeling, prediction, and dynamics of gene-expression patterns. As clearly understood in these days, this enterprise cannot become satisfactory without acknowledging the role of the environment. To a representation of past, present, and most likely future states, we also encounter measurement errors and uncertainties. This paper surveys and improves recent advances in understanding the foundations and interdisciplinary implications of the newly introduced gene–environment networks, and it integrates the important theme of carbon dioxide emission reduction into the networks and dynamics. We also introduce some operational and managerial issues of practical working and decision making, expressed in terms of sliding windows, quadrants (modules) of parametric effects, and navigating (controlling) between such effects and directing them. Given data from DNA microarray experiments and environmental records, we extract nonlinear ordinary differential equations that contain parameters that have to be determined. For this, we employ modern (Chebychevian) approximation and (generalized semi-infinite) optimization. After this is provided, time- discretized dynamical systems are studied. A combinatorial algorithm with polyhedra sequences allows to detect the region of parametric stability. Finally, we analyze the topological landscape of gene–environment networks with its structural (in)stability. By embedding as a module and investigating CO₂ emission control and figuring out game theoretical aspects, we conclude. This pioneering work is theoretically elaborated, practically devoted to health care, medicine, education, living conditions, and environmental protection, and it invites the readers to future research.      

模糊矩阵法在校园声环境质量评价中的应用

由于噪声及其感受主体均具有不确定性的特点,拟采用模糊综合评价方法对声环境质量进行评价,从而使评价结果更具客观性和合理性。本文通过对S大学声环境质量的现状监测并结合在校师生主观感受调查结果,运用模糊矩阵法对校园声环境质量进行综合评价,并对校园声环境质量与教学生活的适宜度进行了分析论证。     

辐射环境监测优化布点的特征分析方法

介绍了特征分析方法的基本原理及其MATLAB语言实现过程,并将特征分析法、传统布点法,以及BP人工神经网络法对同一地区辐射环境监测优化布点的核素含量均值作了比较,结果表明,用特征分析法优选出的采样点位,其核素含量均值对传统布点法的相对偏差均为负值,且＜10%,即便与BP法相比,也不失其优越性,表明用特征分析法监测一个地区环境辐射平均水平的优化布点是十分理想的.

Policy for management of water resources in Greece

The quantities of water are not distributed uniformly in space and time. Greece compared to some other Mediterranean countries is found in advantageous position regarding the availability of water resources. However, there are regions with great in quantity water reserves and others with intense deficiencies. The management of water resources in Greece is concentrated in the systematic spatiotemporal monitoring and forecast of two basic multidimensional parameters, the availability of water resources and the water demand, as well as, in the implementation of necessary measures for the satisfaction of needs, regarding the fields of economy and environment. This work describes and analyses the existing status of water resources in Greece, as well as, the framework of applied policy. Furthermore, measures and actions for the management of water resources are proposed.     

A note on attitudes and knowledge concerning environmental issues in Sweden

As part of a larger research effort, the empirical basis for this note is responses to four out of many questions in a mailed survey, which primarily focused on national environmental objectives in Sweden. The results show that out of eight broad areas for use of tax money, five-including environment-are rated as important by over 90% of the respondents. Respondents appear to be less willing to discriminate between different issues covered by national environmental objectives, as all of these are rated as important by more than 80% of the respondents. The function of the ozone layer is an example of an environmental issue where the knowledge among people is relatively high, while this is not the case when it comes to the amount of pesticides used in agriculture. The results also show less support for actions at the individual level to improve the environment, as compared to support for actions taken by society at large through, e.g., technological improvement or policy intervention.     

Biodiversity Offsets: Two New Zealand Case Studies and an Assessment Framework

Biodiversity offsets are increasingly being used for securing biodiversity conservation outcomes as part of sustainable economic development to compensate for the residual unavoidable impacts of projects. Two recent New Zealand examples of biodiversity offsets are reviewed—while both are positive for biodiversity conservation, the process by which they were developed and approved was based more on the precautionary principal than on any formal framework. Based on this review and the broader offset literature, an environmental framework for developing and approving biodiversity offsets, comprising six principles, is outlined: (1) biodiversity offsets should only be used as part of an hierarchy of actions that first seeks to avoid impacts and then minimizes the impacts that do occur; (2) a guarantee is provided that the offset proposed will occur; (3) biodiversity offsets are inappropriate for certain ecosystem (or habitat) types because of their rarity or the presence of threatened species within them; (4) offsets most often involve the creation of new habitat, but can include protection of existing habitat where there is currently no protection; (5) a clear currency is required that allows transparent quantification of values to be lost and gained in order to ensure ecological equivalency between cleared and offset areas; (6) offsets must take into account both the uncertainty involved in obtaining the desired outcome for the offset area and the time-lag that is involved in reaching that point.
