Game Research on Property Right Evolution of Small Water Conservancy Projects under the Conflict of Multi-Stakeholders

The property right of small water conservancy projects (hereinafter referred to as SWCP) currently can be defined as three different forms: public property rights, private property rights, and a combination of public and private property rights. The main participants are the government, farmers, and other organizations. The interests and demands of different subjects are different, so the property rights structure of the SWCPs are also different. In order to explore the evolutionary law of the property right structure of SWCPs in the case of conflicting demands of multiple stakeholders, a game model for the evolutionary law of each main body of SWCPs was proposed in this paper. By analyzing the feasibility of the game of multi-stakeholder appeal conflicts, a multi-stakeholder game model was established. The game and evolution of each stakeholder were analyzed, and the evolution of the property rights of SWCPs under the game of each subject was simulated and analyzed. The research results show that if the incentives and constraints of cooperation between farmers and cooperatives, associations and other organizations are greater than the cost of cooperation, farmers will participate in the cooperation and invest in elements actively, thus promoting the integration of elements, thereby contributing resource complementarity among participants and leaving more cooperation surplus. If the benefits of cooperation between the government and farmer organizations plus the total benefits of the incentive and restraint mechanism are greater than the total cost of active cooperation, furthermore, the incremental benefits of the incentive and restraint mechanism are not lower than the incremental costs of participating in the cooperative, then, farmer organizations are easier to get succeed. The research results have certain reference significance for the option of the property rights and management modes of SWCPs.

Research on Incentive and restraint mechanism of capital operation of power grid enterprises under new development pattern

Under the new development pattern of dual circulation economy, the reform of state-owned enterprises has entered the deep water area, and the operating environment of power grid enterprises has changed significantly, which has a profound impact on the capital operation strategy and effect of the enterprises. This paper analyzes the new characteristics of capital operation of power grid enterprises under the new development pattern, constructs the incentive and restriction index system of capital operation of power grid enterprises, designs the incentive and restraint mechanism of capital operation of power grid enterprises, and verifies the scientificity and applicability of the mechanism by financial evaluation and analysis. The research results enrich the theory of capital operation management based on financial evaluation, and provide theoretical basis and practical reference for grid enterprises to optimize the distribution of capital investment and improve the efficiency of capital operation.

Equality in Immigration Law: An Impossible Quest?

The aim of this article is to discuss why the principle of equality and non-discrimination, although foundational to international human rights law, remains an unfulfilled promise in the context of immigration. Nationality is now widely considered as a suspect ground of discrimination, yet contemporary immigration and citizenship laws increasingly use meritocratic criteria to distinguish among migrants. Although framed in universal terms, these criteria create differences of treatment among migrants based on their income, level of education and economic worth. However, from a legal perspective such differences of treatment rarely amount to prohibited discrimination. Looking at the case law of the European Court of Human Rights, this article argues that the normative content of the equality and non-discrimination principle fails to challenge such differences of treatment. Moreover, the proportionality test is used as a judicial restraint mechanism which prevents the effective enforcement of the equality requirement by international and domestic courts in the context of immigration.

The Application of Double Qualified Teachers in the Teaching of Ideological and Political Course for the Transformation and Development Model Universities

The ideological and political teachers are in a weak link in the construction of the double qualified teachers in the transformation and development model universities. We must give full play to the unique role of the double qualified teachers in the ideological and political course teaching, in order to strive to improve the teaching quality and enhance the effectiveness. On the basis of preliminary practice and exploration, we should take the road of optimizing incentive with restraint mechanism and practical training.

Rotational Restraint to Purlins Provided by Standing Seam Roof Systems

The finite element model used for analyzing the rotational restraint rigidity of standing seam roof systems was developed. The influences of different factors on the rotational restraint rigidity provided by two types of standing seam roof systems were studied. The variables include local deformation of standing seam roof panels, panel thickness, clip tab thickness, and the relative sliding of clip tab and clip base. The restraint mechanism of standing seam roof systems to the purlins was studied. It is shown that the rotational restraint rigidity provided by the two types of researching standing seam roof systems mainly depends on the slide tab thickness and the roof panel thickness. Finally, formulae for calculating rotational restraint rigidity of the LSIII and SS360 standing seam roof systems were also proposed based on parametric analysis results.

113 Influence of cattle stress response to restraint method on artificial insemination pregnancy rates

Activation of physiological stress responses have been associated with decreased pregnancy rates in beef cattle. Therefore, alternative cattle restraint methods have been developed to reduce this negative impact. However, little evidence exists comparing pregnancy outcomes of differing methods. Thus our objective was to determine if a difference was present in pregnancy rate to fixed-time artificial insemination in Bos taurus beef females when using a breeding box (b) versus a squeeze chute (c). Cows and heifers from two separate locations (Virginia Tech University, VT; and R.A. Brown Ranch, RAB) were exposed to FTAI protocols at location of origin while restrained in a squeeze chute (n = 169) or a breeding box (n = 162). Females were exposed to the 7 day Co-Sync + CIDR protocol pre-breeding. At day of breeding, females were randomly assigned to treatment. Immediately following breeding, blood was collected via coccygeal venipuncture for assessment of plasma cortisol concentration using an automated ELISA assay (Immulite 2000 XPi, Siemens). Chute and Exit Score (1–5) were assessed at the time of breeding by a trained technician at each location. Pregnancy was verified thirty days post-breeding via rectal ultrasonography. Pregnancy rate (PROC FREQ) and cortisol (PROC GLIMMIX) were analyzed using SAS version 9.4. Also, a Linear Regression Model (SAS version 9.4) was used to determine relationships between chute score, exit score, and cortisol. It was found that there was no difference in pregnancy rate between the breeding box and the squeeze chute (61.73% vs 64.71%, P = 0.31, respectively). Cortisol showed no difference between b and c (59.44±10.17 vs 58.61±10.16, P = 0.68, respectively). There was no linear relationship between cortisol, exit score, and chute score (P = 0.14). It can be concluded that stress responses are similar between the breeding box and squeeze chute. Therefore females will have similar pregnancy rates when exposed to FTAI in either restraint mechanism.

On the restraint mechanism between the earth and moon

The moon always use the same side to face toward the earth, but there is a dead angle in the mainstream theory of explaining this phenomenon. That is, it cannot explain why the moon doesn't rotate around the axis which is a straight line to connect the mass centers of the earth and moon. Because the numerous meteorite impact craters on the lunar surface indicate that the moon is completely possible to obtain external momentums and rotate around this axis. This paper proposes a plain explanation, that is, the universal gravitation between the earth and moon as well as the earth's magnetic field have formed a trinity restraint mechanism on the moon. According to this explanation, the moon's rotation can be locked, and the mechanism of lunar libration has been revealed out, which can also confirm mutually with the natural phenomenon that the moon has sought a balance in the swing. In addition, with the help of all kinds of detection data from the Apollo moon landings and other circumlunar spacecraft, as well as the studies and analysis of lunar soil samples, the conclusion is that as far as a whole for the moon, it belongs to paramagnetic substances, and its relative permeability is between 1.008 and 1.03. Although the magnetic flux density of the earth on the lunar orbit has been dropped below 0.0008125 nT or lower due to the impact of the solar wind, but it can be used as a reason to lock the moon without rotating around the axis which is a straight line to connect the mass centers of the earth and moon. If another main reason to cause the existence of this fact cannot be found, even if the magnetic flux density of the geomagnetism in lunar orbit is very small, it also should not be artificially ignored. In this regard, we can artificially change the intensity of the earth's magnetic field, and carefully observe the lunar libration and in the distance between the earth and the moon, to verify the arguments in this paper.

Dynamic Characteristics and Restraint Mechanism of Elastically Restrained Connecting Joints on the Flexible Robotic Manipulator

Connecting joints are significant components in mechanical systems as well as the Cartesian flexible robotic manipulator (FRM) which consists of a flexible arm and a moving base through connecting joints. Uncertain factors, such as unqualified assembly, accidental collision, and longtime service, will reduce the restraint stiffness of the connecting joints and enhance the dynamic nonlinearity of the system subsequently. In this case, the traditional perfectly fixed restrained model cannot reflect the real property of the connecting joints. This paper focuses on the elasticity property of the connecting joints with uncertain restraint stiffness, which is defined as the elastically restrained connecting joints (ERCJ), and investigates the dynamic characteristics and restraint mechanism of the ERCJ. An elastic restrained model is proposed to describe the elasticity property of the connecting joints and determine the elastic restrained region of the ERCJ, and the frequency relationship equation in the elastic restrained region is simultaneously determined and verified. Based on the proposed elastic restrained model and Hamilton’s variational principle, the dynamic model and vibration displacement equation of the FRM with elastically restrained connecting joints (FRMERCJ) are established. The virtual prototype experiment of the FRMERCJ is conducted to verify the dynamic model and reveal the restraint mechanism of the ERCJ. The proposed elastic restrained model in this paper can accurately describe the elasticity property of the connecting joints, and the ERCJ is sensitive to motion velocities especially under higher velocities for higher-order vibrations in the initial stage. The results are meaningful for the dynamic analysis and vibration control of robotic manipulators.
