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.     

光源、性别及光处理时间对草地贪夜蛾趋光行为的影响

为研发高效、精准的监测防控设备,利用八臂行为选择装置系统测定不同光源、性别和光处理时间下草地贪夜蛾Spodoptera frugiperda的趋光行为。结果显示,在紫外光（波长365 nm）、紫光（波长420～430 nm）、蓝光（波长465～475 nm）、绿光（波长525～535 nm）、黄光（波长585～595 nm）和红光（波长655～665 nm）6种波长光源下,草地贪夜蛾混合种群（雌雄成虫比为1∶1）对紫外光光源的趋光选择率最高,为25.61%,显著高于其他处理,其次为紫光和蓝光光源,趋光选择率分别为16.30%和8.82%,对红光的趋光选择率最低,为4.76%。在紫外光刺激下,草地贪夜蛾雌成虫的趋光选择率显著高于混合种群（雌雄成虫比为1∶1）,在红光刺激下,雄成虫的趋光选择率显著高于雌成虫。另外,在紫外光刺激下,光处理时间60 min草地贪夜蛾雌成虫的趋光选择率显著高于其他处理。表明光源与性别因素均影响草地贪夜蛾的趋光行为,光处理时间对草地贪夜蛾的趋光行为影响较小,且与光源及性别因素有关。     

影响猪采食行为的肠道微生物种类鉴别

动物主要通过采食来获取能量和所需营养物质,探索肠道菌群对猪采食行为的影响并研究其潜在的作用机制,可以为后续通过调控肠道菌群来改善猪采食提供理论基础。以210头商业杜洛克猪为研究对象,使用自动喂料器记录包括平均日采食时间(ADET)、平均日采食次数(ADEV)、平均日采食量(ADFI)等采食行为指标。140日龄时于肛门处收集粪便样品,通过16S rRNA基因V3-V4区测序获得试验猪肠道微生物结构与组成概况,采用Two-part模型以及共丰度组(CAGs)鉴别与猪采食行为相关的肠道微生物种类。结果显示：1)表型间相关性分析结果表明,ADET分别与ADEV(r=0.41,P<0.05)、RFI(r=0.32,P<0.05)呈显著正相关,ADFI分别与RFI(r=0.56,P<0.05)、平均日增重(ADG)(r=0.63,P<0.05)呈显著正相关,另外,RFI与背膘厚呈显著正相关(r=0.16,P<0.05)。2)CAGs分析中,主要包括瘤胃球菌科(Ruminococcaceae)、拟杆菌目(Bacteroidales)以及颤螺菌属(Oscillospira...

Enterprise Information Engineering Model and Its Integrated Support Environment

By analyzing the process of enterprise information engineering construction and intra relationship among information system requirement, business process modeling, application system constructing and project management, one of 4 meta model composed of requirement engineering, process engineering, application system engineering and support engineering is proposed for enterprise information engineering. The developments and applications of the business processes and its application systems are integrated into the same development space and application space. Basing on this, a prototype system composed of requirement modeling environment, business process modeling environment, application system modeling environment, and support engineering environment has been designed and built, which is used for supporting enterprise information engineering constructing. It is valued for the enterprise information engineering construction in our country.     

Slab Defect Diagnosis and Predicting System Based on Rough Set Theory

In accordance with the special characteristics of state medium-sized construction enterprises and their reform objects of "having a free hand and enlivening", the suitable objective model, the stock cooperative system for state medium-sized construction enterprises has been put forward in this paper by analyzing the system mechanism of stock cooperative system enterprises. Then the causes for it were expounded.     

Design on Enterprise Informationization Estimates the Model of Composite Index

This peper commentaried some of our country comparatively well-known enterprise informationization estimate theory,point out,there is existing the question of informationization estimates,that the achievement can't guarantee "appropriate informationization" establishing and enterprise informationization sustainable development,It propose the three-dimensional enterprise informationization estimate the theory and method,that includes information-based level,information-based quality and information-based development potentiality.
