"全党办报、群众办报"话语的历史缘起与建构动力

在马克思主义新闻观中国化进程中,"全党办报、群众办报"的文本建构历经了孕育、萌芽、形成和发展等诸多阶段,期间不但伴随着"同人办报","精英办报(少数人办报)"等多重话语博弈与纠缠,而且还深度统摄着话语生产主体的价值诉求与新闻情怀,鲜活表征着时代背景因子与历史必然元素.

自我构念:文化的动力建构过程

对"自我"的研究一直是心理学领域的核心问题。而社会文化影响自我构念又是心理学研究自我的一个很重要的新的视角。尤其是近几年从文化的动力建构过程来研究自我构念,这对于以前静态的观点是一个很大的挑战。动力建构理论认为个体同时存在两种文化倾向的自我构念:集体主义自我构念和个体主义自我构念,在不同的启动情景下个体表现出不同的自我构念。由于东西方文化背景的不同,两种自我在个体中的表现程度不同,西方个体表现更多的个体主义,东方个体表现更多的集体主义。随着政治、经济、文化全球化的日益发展,两种倾向的自我构念也在不断地变化着。

内外协同与推拉并举:新时代党员干部党史学习教育的动力建构

新时代党史学习教育只有不断激发学习动力、构建长效机制,才能更好实现向常态化、长效化推进。学习动力对学习实践的影响是潜在的、长远的,动力不足会严重影响党员干部的学习心态和学习效果。中国共产党立足新时代党史学习教育实践,在把握党员干部党史学习“源动力”基础上,不断塑造“原动力”、优化“驱动力”,通过满足内需、增进外压、营造生态等方式促成由“要我学”向“我要学”的学习动机转变和系统动力建构,实现党员干部“学得好”的恒久效能,将中国共产党学习研究党史的作风传统巩固转化为党高质量、高水平建设的稳定机制。

论政府信任的结构:基于于镇的个案调查

政府信任结构主要由建构动力、建构策略和建构模式组成。政府信任的建构动力主要基于两点:一个是熟人社会,另一个是寻利动机。政府信任的建构策略包括了"情感—互动"、编织关系网、运用地方性知识三种。而政府信任的建构模式则主要考虑四种因素:一是纵向结构和横向结构;二是信任范围;三是强关系和弱关系;四是日常监控。

社会心态形成的心理机制及效应

作为一种最为宏观和复杂的社会心理现象,社会心态的形成机制异常复杂。社会心态具有共享现实性的特征。从动力建构理论出发提出社会心态的向上模型、向下模型和互动模型,并且对社会心态互动模型中的相关重要变量,如社会认同、情绪感染、去个人化与去个体化、关系化进行阐述,可以进一步探讨社会心态的内部机制。社会心态的形成过程会带来一定的社会心理效应,如汇聚效应、多数人与少数人效应、群体极化效应、群体参照效应和皮格马利翁效应。

The height-width ratio limited value for rubber bearing isolated structure computed by uniform design method

Rubber isolation is the most mature control technology in practical application, and is widely used by short rigid buildings. However, many high isolation buildings have been built around the world in recent years, which do not follow the existing criterions and codes. Many researchers began to research the special problems caused by larger height-width ratio isolation structures. The overturning effect of high height-width ratio structures with rubber bearing is firstly studied. Considering the main factors, such as the height-width ratio of structures, type of site, the designed basic acceleration of ground motion and the decouple factor in horizon, computing experiment is defined with the Uniform Design Method, which is also known as designing isolation structure. The forces of the bearing under edge of structures based on the position of the rubber bearing are calculated. The result indicates that the rubber bearings will lose its functionality under very high tension and compressing force of earthquake motion in horizon and vertical, when the height-width ratio is over a certain value. Thus, based on the calculation result of isolation structures defined in the uniform design method, regression analysis is conducted, and also the rubber edge force regression formula are gotten, which has higher correlation and smaller standard deviation. This formula can be used to roughly calculate whether the pull force occurs at the edge of the building. By the edge bearings of isolation structure minimum force formula, the height-width ratio limited value of the isolation structure is deducted when rubber bearing has minimum force of zero.

Modeling approaches to pressure balance dynamic system in shield tunneling

In order to deal with modeling problem of a pressure balance system with time-delay, nonlinear, time-varying and uncertain characteristics, an intelligent modeling procedure is proposed, which is based on artificial neural network(ANN) and input-output data of the system during shield tunneling and can overcome the precision problem in mechanistic modeling(MM) approach. The computational results show that the training algorithm with Gauss-Newton optimization has fast convergent speed. The experimental investigation indicates that, compared with mechanistic modeling approach, intelligent modeling procedure can obviously increase the precision in both soil pressure fitting and forecasting period. The effectiveness and accuracy of proposed intelligent modeling procedure are verified in laboratory tests.

On the Possibilities of Leisure Studies in Mozambique： Historical and Sociological Considerations

In this paper, the author examines the possibilities of leisure （studies） in Mozambique. First, the author suggests that leisure can he looked at as a social construct which resulted from the colonial regulation of native labour, particularly between 1890s and 1974. Secondly, the author proposes that people look at the conditions of possibility of leisure in a context dominated by the new moral code of conduct, a cathartic purification of the colonial mentality, introduced through the ideology of the ＂New Man＂ created by the ruling party, Frelimo. Thirdly, the author examines the possibility of leisure in the context of Mozambique＇s adherence to neo-liberalism and market-driven economy after the collapse of socialism. The author concludes by providing the ground to establish lines of inquiry for an eventual field of leisure studies.

Dynamics Simulation Model of the Economic System in Mining Area

The system dynamics is a new subject that was put forward by Professor J W. Fortester in dmerican MIT in 1950s. It is extensively applied to systematic problems af high phase, nonlinear, multtdimensionality, multiple feedback and complicated time-variation. In this paper, the complex system in mining area is divided into five parts - resources, environment. economy, population, and science and technology. The.five parts are regarded as five sub-models. By taking the economic subsystem as an example, the SD model of complex system in mining area is established. This model has certain universality and practicability.

Nature and Kinetic Architecture： The Development of a New Type of Transformable Structure for Temporary Applications

The contemplation of contemporary architectural designs shows an increasing demand for the development of more adaptable, flexible and transformable structures. This type of structures can adapt with different environmental conditions and meet different functions. This can help in reducing environmental waste and pollution associated with many buildings and above all can save on cost and time. Natural systems have inspired human being, since they began to build and design. Architects and designers have utilized nature as one of the main resources of information for the creation of innovative architectural spaces. One of the unique features of natural structures is the way that their components open and close in order to respond to a particular requirement or the environmental changes. This aspect has inspired many designers for the development of transformable architectural structures that can change their shape and geometry to be able to adapt with specific conditions. To make a way toward the design of transformable structure for temporary applications, the authors have developed a new type of adaptable structures according to natural forms. The proposed design applies the transformation principles that exist in potato＇s flower and the movement mechanisms used in a spider＇s leg. The design is able to fit to different topographies and have a potential to be folded to a very compact state in a very short period of time. The detailed design and the different configurations of the system applications will be presented in this paper. The result of the study shows that using modular triangular plates can create a changeable module that is not only able to respond to different functions and environmental changes but it is also able to shape different configuration to be able to respond to different user＇s ambitions. The compactability of this structure into 1/3 of its base dimensions; makes its transportation fast and with minimum costs. These capabilities make this structure suitable for temporary buildings such as exhibitions, temporary settlements or hospital in damaged areas.

The Effect of Micro Air Movement on the Heat and Moisture Characteristics of Building Constructions

The research focuses on the effect of air movement through building constructions. Although the typical air movement inside building constructions is quite small （velocity is of order -10-5 m/s）, this research shows the impact on the heat and moisture characteristics. The paper presents a case study on the modeling and simulation of 2D heat and moisture transport with and without air movement for a building construction using a state-of-art multiphysics FEM software tool. Most other heat and moisture related models don＇t include airflow or use a steady airflow through the construction during the simulation period. However, in this model, the wind induced pressure is dynamic and thus also the airflow through the construction is dynamic. For this particular case study, the results indicate that at the intemal surface, the vapor pressure is almost not influenced by both the 2D effect and the wind speed. The temperatures at the inner surface are mostly influenced by the 2D effect. Only at wind pressure differences above 30 Pa, the airflow has a significant effect. At the extemal surface, the temperatttres are not influenced by both the 2D effect and the wind speed. However, the vapor pressure seems to be quite dependent on the wind induced pressure. Overall it is concluded that air movement through building materials seems to have a significant impact on the heat and moisture characteristics. In order to verify this statement and validate the models, new in-depth experiments including air flow through materials are recommended.

ODE-Solver-Oriented Computational Method for the Structural Dynamic Analysis of Super Tall Buildings

The paper is to introduce a computational methodology that is based on ordinary differential equations （ODE） solver for the structural systems adopted by a super tall building in its preliminary design stage so as to facilitate the designers to adjust the dynamic properties of the adopted structural system. The construction of the study is composed by following aspects. The first aspect is the modelling of a structural system. As a typical example, a mega frame-core-tube structural system adopted by some famous super tall buildings such as Taipei 101 building, Shanghai World financial center, is employed to demonstrate the modelling of a computational model. The second aspect is the establishment of motion equations constituted by a group of ordinary differential equations for the analyses of free vibration and resonant response. The solutions of the motion equations （that constitutes the third aspect） resorted to ODE-solver technique. Finally, some valuable conclusions are summarized.

Modeling and analysis of a predator-prey model with state-dependent delay

We propose and study a predator prey model with state-dependent delay where the prey population is assumed to have an age structure. The state-dependent delay appears due to the mature condition that the prey must spend an amount of time in the immature stage sufficient to accumulate a threshold amount of food. We perform a qualitative analysis of the solutions, which includes studying positivity and boundedness, existence and local stability of equilibria. For the global dynamics of the system, we discuss an attracting region which is determined by solutions, and the region collapses to the interior equilibrium in the constant delay case.

Geodynamic modeling of thermal structure of subduction zones

During subduction processes, slabs continuously have heat exchange with the ambient mantle, including both conduction and advection effects. The evolution of slab thermal structure is one of the dominant factors in controlling physical and chemical property changes in subduction zones. It also affects our understanding of many key geological processes, such as mineral dehydration, rock partial melting, arc volcanism, and seismic activities in subduction zones. There are mainly two ways for studying thermal structure of subduction zones with geodynamic models: analytical model and numerical model. Analytical model provides insights into the most dominant controlling physical parameters on the thermal structure, such as slab age, velocity and dip angle, shear stress and thermal conductivity, etc. Numerical model can further deal with more complicated environments, such as viscosity change in the mantle wedge, coupling process between slabs and the ambient mantle, and incorporation of petrology and mineralogy. When applying geodynamic modeling results to specific subduction zones on the Earth, there are many factors which may complicate the process, therefore it is difficult to precisely constrain the thermal structure of subduction zones. With the development of new quantitative methods in geophysics and geochemistry, we may obtain more observational constraints for thermal structure of subduction zones, thus providing more reasonable explanations for geological processes related to subduction zones.

Modeling of microbial growth bioprocesses： Equilibria and stability analysis

The paper addresses the analysis of nonlinear dynamical models of some microbial growth processes. Equilibrium points, stability analysis, and structural properties are studied for different bioprocesses with various kinetics structures. First, a simple micro- organism growth process on a single limiting substrate is widely analyzed. Second, a microbial growth process combined with an enzyme-catalyzed reaction is investigated. The analysis shows that these kinds of bioprocesses have multiple equilibria, stable or unstable, operational or non-operational. The partition of nonlinear model in linear and nonlinear parts via some structural properties leads to kinetic decoupling and facilitates the equilibria and stability analysis. The performed research is useful for model reduction and for the design of observers and control algorithms. To illustrate the study results, several numerical simulations are provided.
