This article analyses differences in the attitudes related to climate change of young scholars in environmental science in Qingdao (China) and Hamburg (Germany). The main aim of the article is to evaluate the role of cultural differences for their explanation. We expect no significant differences in the attitudes related to the findings of climate research, since scientific principles are the joint basis of the scientific discourse wordwide. However, we expect that there are differences in the attitudes of the young scholars about the role of science, of the state and of the civil society for dealing with the challenge of climate change. We suggest that these can be explained with substantial cultural differences between both societies, with regard to the role of the state and the civil society for the solution of environmental problems. In order to evaluate these hypotheses, we have conducted a comparative survey among environmental science students in Qingdao (China) and Hamburg (Germany) about their attitudes towards climate change. The findings support our main hypotheses. The young scholars in Qingdao and Hamburg differ substantially in their views of the role of science in society and policymaking. Plausibly, these differences may mainly be explained with differences in the cultural ideas about the role of the state and of the civil society for the solution of environmental problems. Gradual differences in the share of young scholars who think that climate change has anthropogenic causes, may be explained with differences in the curriculum but also by cultural habits. This article makes a new contribution to the scientific debate by exploring the role of cultural differences for differences in the attitudes of young scholars in environmental science in connection with climate change and climate policy in different cultural contexts.

Principles to Support Modular Software Construction

引用

Journal of Computer Science & Technology 2017年第1期32卷 3-10页

作者： Jack B. dennis Department of Electrical Engineering and Computer Science Massachusetts Institute of Technology Cambridge MA 02139 U.S.A.

The construction of large software systems is always achieved through assembly of independently written components -- program modules. For these software components to work together, they must share a common set of data types and principles for representing structured data such as arrays of values and files. This common set of tools for creating and operating on data objects is provided by the infrastructure of the computer system： the hardware, operating system and runtime code. Because the nature and properties of these tools are crucial for correct operation of software components and their inter-operation, it is essential to have a precise specification that may be used for verifying correctness of application software on one hand, and to verify correctness of system behavior on the other. We call such a specification a program execution model （PXM）. It is evident that the properties of the PXM implemented by a computer system can have serious impact on the ability of application programmers to practice modular software construction. This paper discusses the concept of program execution models and presents a set of principles that a PXM must satisfy to provide a sound basis for modular software construction. Because parallel program execution on computer systems with many processing units is an essential part of contemporary computing environments, the expression of parallelism and modular software construction using components involving parallel operations is included in this treatment. The conclusion is that it is possible to build computer systems that implement a PXM within which any parallel program may be used, unmodified, as a component for building more substantial parallel programs.

?Ethene/norbornene copolymerization by the catalyst system [Me_2Si( 3- tertBuCp)(N tertBu)]TiCl_2/MAO was investigated in detail at 30 ℃, 60℃, and 90℃. A mass flow controller was used in this work to obtain kine tic data and investigate tempera ture's effects on activity, norbornene incorporation, copolymerization parameter , microstructure, glass transition temperature, and molar masses were described. H igh copolymerization values r_E and high alternation are determined. The n umber of isotactic alternating sequences is much higher than that of the syndiot actic alter nating sequences.

Investigations into the identification and control of outburst risk in Australian underground coal mines

引用

International Journal of Mining Science and Technology 2017年第5期27卷 749-753页

作者： dennis J.Black PacificMGM Bulli 2516Australia Department of Civil Mining and Environmental EngineeringUniversity of WollongongWollongong 2500Australia

Australian coal mines currently use gas content to assess outburst risk. The gas content threshold values for each mine are indirectly determined from measurement of gas volume liberated from 150 g coal samples during Q_3 residual gas content testing. It has been more than twenty years since this method, known as desorption rate index(DRI), was presented to the Australian coal industry, and in that time, there have been significant changes in mining conditions and the outburst threshold limits used at the benchmark Bulli seam mines. NSW Regulations list matters to be considered in developing control measures to manage the risk of gas outburst, and specifies that gas content, or DRI method, is used as the basis for determining outburst control zone. Whilst Queensland Regulations state that a coal or rock outburst is a high potential incident, there is no guidance provided to assist mine operators to define outburst prone conditions. A research project is planned at UOW to investigate the application of the DRI method and other potentially significant factors, such as gas pressure, coal toughness and permeability, which can be utilised by mine operators to assess outburst risk and determine appropriate outburst threshold limits and controls.
