《毛泽东思想和中国特色社会主义理论体系概论》教学改革探讨

“概论”课理论性、现实性很强,在当前我国社会转型和改革攻坚深刻影响人们思想的形势下,如何讲好“概论”课对教师的教学理念、教学方法、技能和知识结构都提出了很高的要求.笔者在认真分析学生对思想政治理论课需求的基础上进行了一系列教学方法改革和实践：坚持理论联系实际,讲好讲活理论；采取互动教学方法,让学生更多的参与教学；灵活运用多媒体技术；通过实践教学促进课堂教学；举办多种专题讲座,拓展学生思维和视野.     

马克思自然生产力理论及其对我国生态文明建设的启示

马克思的自然生产力的思想和理论内容,主要是认为客观的自然界有一种自然力量对人类的生存和发展发生着直接或间接的影响。这些自然力量的总和就是自然生产力。文章对马克思的自然生产力理论作一个深入的挖掘、梳理,研究分析其深刻内涵和主要内容,并阐述其对我国当代社会主义生态文明建设的理论启示和现代实践价值。     

Describing Human–Wildlife Interaction from a European Perspective

European researchers from both the natural and social sciences show growing interest in studying interactions between society and wildlife. A wealth of theoretical frameworks, concepts, and methods are used, but an integration of perspectives is lacking. This research note summarizes results from two workshops that included 63 delegates from 25 European countries, as well as a follow-up survey of 41 respondents. Two main theoretical approaches to the study of human–wildlife interactions were identified. One approach focuses on the collective societal level relying on theories of governance, social representation, deliberative procedures, and commons theory. The other approach targets individuals or groups, and is based on theories such as the cognitive hierarchy, theory of reasoned action, and theory of planned behavior. Interdisciplinary collaboration is needed to identify the best options for wildlife conservation and management in a more politically integrated Europe.

Association between porpoise presence and fish choruses: implications for feeding strategies and ecosystem-based conservation of the East Asian finless porpoise

The associations between feeding activities and environmental variables inform animal feeding tactics that maximize energetic gains by minimizing energy costs while maximizing feeding success. Relevant studies in aquatic animals, particularly marine mammals, are scarce due to difficulties in the observation of feeding behaviors in aquatic environments. This data scarcity concurrently hinders ecosystem-based fishery management in the context of small toothed-cetacean conservation. In the present study, a passive acoustic monitoring station was deployed in an East Asian finless porpoise habitat in Laizhou Bay to investigate potential relationships between East Asian finless porpoises and their prey. The data revealed that porpoises were acoustically present nearly every day during the survey period. Porpoise detection rates differed between spring and autumn in concert with activities of fish choruses. During spring, fish choruses were present throughout the afternoon, and this was the time when porpoise vocalizations were the most frequently detected. During autumn, when fish choruses were absent, porpoise detection rates decreased, and diurnal patterns were not detected. The close association between fish choruses and finless porpoise activities implies an “eavesdropping” feeding strategy to maximize energetic gains, similar to other toothed cetaceans that are known to engage similar feeding strategies. Underwater noise pollution, particularly those masking fish choruses, could interrupt finless porpoises’ feeding success. Fisheries competing soniferous fishes with finless porpoise could impact finless porpoise viability through ecosystem disruption, in addition to fishing gear entanglement.

New Progression about Gravity Quantization in General Relativity Theory in Real Space-time

Professor Venzo de Sabbata,working at World Laboratory,Lausanne,Switzerland,and Department of Physics,University of Bologna and Ferrara,Italy,is a famous Italy Physicist in the world.He is engaged with a series of creating research works about gravity quantization of General Relativity Theory in the real space-time which attract the attentions of the world.This paper pays the attention to introduce the works of this field,containing mainly:1.quantizing the general relativity theory in the sense of Einstem-Cartan theory,i.e., general relativity adds the torsion,which means introducing spin into the theory of gravity.2. building a compact mathematical tool for research of gravity quantization,the geometric algebra in the real space-time--multivector algebra,i.e.,developing a spinor manifold in the real space-time.     

Density Functional Theory Compute on Electronegativities to Superconductivity of Oxides

In this article we have worked out the correlation between electronegativity and high temperature superconductivity for oxide. It is suggested the equalized electronegativity, X cq , can be used as a empirical criterion for superconductivities of oxides. For determining the X cq , a new formula for the calculation of X cq values has been obtained The X cq values of 230 oxide superconductors have been calculated. The result shows that the X cq values of all the oxide superconductors concentrate in a narrow range from 5.00 to 5.63 and that the oxides with values out side this region would be non-superconductive. This criterion can be applied to almost all the oxide superconductors. It is clearly that this result is able to benefit further inquiries about the mechanism of superconductivity.     

Multilevel Fuzzy Theory Evaluation of the Tourism Resources in the Three Gorges Reservoir

Complexity of mutual act and different sensation of different tourists are important factors influencing regional tourism resources evaluation. Fuzzy mathematic method can be used to up quantitative evaluation method on tourism resources evaluation. Taking Wushan Small Three Gorges as an example, the author carries out the evaluation of the tourism resources in the Three Gorges Reservoir. At the same time, the authors consider that five factors, such as improvement of the comunication of tourism resources, quickening the Steps of urbanization in reservior area, must be done well.
