From the perspective of civil subject theory,law of value,comparative law and history of laws,the thesis expounds that the contract on the transfer of the contractual right of rural lands is in nature a civil contract instead of an administrative one.Then it explores the defects in the contract from the viewpoint of legal value goal,contract law and legal sociology,that is,the relevant provisions in Rural Land Contract Law and Explanations of Supreme People's Court about the Issues concerning the Laws Applicable to the Trial of Cases of Disputes over Rural Land Contracting go against the principle of free contracting and run counter to the legal value goal of justice,so they do not achieve good implementing effect.Finally,the thesis demonstrates and makes some practical legislative proposals to perfect the contract system for circulation of the right to operate constructed rural lands,aiming at improving the circulation rate through perfecting the contract of the right to rural land contractual management,solving the disputes in rural lands circulation and safeguarding the legitimate rights of the farmers. 展开更多

Labor Contract Law receives mixed evaluations since its implementation.The call for the amendment is hot and even some scholars regard it as the"tiger in the road"which hinders the economic development. The Central Committee of the Communist Party of China pays high attention to the construction of harmonious labor relation and the amendment has been a top priority. Labor Contract Law leads to two"deadlocks"of which the entrepreneurs are afraid. The first one is that the non-fixed term labor contract cannot be cancelled and the second one is that they must pay the economic compensation at the expiration of contract. These two rules hinder the employment enthusiasm of entrepreneurs. The current laws have excessive expectation for the non-fixed term labor contract and too strict regulations; as for the economic compensation at the expiration of contract, it increases the enterprise cost. The amendment of these two articles will benefit the recovery of Chinese economy and make the labor relation more harmonious. 展开更多

Death with dignity is the embodiment of the dignity of human life in the context of end-of-life medical care.However,in the development of its concept,it has been alienated into a single way of death and is often confused with the concept of euthanasia.It is therefore a theoretical and practical necessity to re-expand the connotations of death with dignity Death with dignity is the subjective value of dignity reflected in the context of dying.It takes equality,freedom,and virtue as the core,and uses the right to life as its external support.It is projected onto the medical context and incorporates the patient’s right to informed consent.Subject to public interest,legal paternalism,and the principles of public order and good customs,the boundary of the right to death with dignity should be between active treatment and natural death,and active euthanasia in the form of giving up the right to life should not be included in the right to death with dignity. 展开更多

Objective:To observe the HRV changes before and after the radiofrequency current catheter ablationventricular premature beats originated from different site of right ventricular outflow tract.Methods:A total of 102 patients with frequent RVOT-VPC admitted to our hospital were accepted radiofrequency current catheter ablation (RF). According to the origin of RVOT-VPC, it was divided into 2 groups, one is from ventricular septum, and the other one is from free wall, and in each group, male and female are observed separately.Results:(1) HRV before RF ablation: 1) rMSSD in the female patients with RVOT-VPC from free wall was significantly lower than those from septum;2) frequency domain index (W, LF) were higher than normal range, and in male patients, LF/HF<1 were found, but in female patients, LF/HF>1. (2) HRV after RF ablation: 1) Significant changes were found in female patients with RVOT-VPC from septum, rMSSD, PNN50, HF and LF decreased;2) In female patients with RVOT-VPC from free wall, rMSSD decreased;3) In male patients, there were no significant HRV changes found before and after RF ablation. (3) Heart rate changes: 1) In female patients with RVOT-VPC from septum, heart rate decreased significantly ((76.47±9.47) bpm vs (69.29±14.59) bpm)2) No significant changes were found in male patients.Conclusion:In patients with RVOT-PVC sympathetic and vagus excitability increased, and after catheter ablation, in female patients with RVOT-PVC originated from septum, the HRV index relating to sympathetic and vagus excitability significantly decreased. 展开更多

The unilateral disposition of stock rights' voting rights detracts from the welfare of the other shareholders. Contractual arrangements restricting or prohibiting the transfer of stock rights under the capital majority rule may infringe upon shareholders' fight of withdrawal, further weakening stock market constraints on senior management and indirectly raising the agency cost of management abuse of power for private ends. In creating a legal structure for stock rights transfer, we need to find an appropriate balance between freedom of contract, capital majority rule and reduction of agency costs. Judges should determine that the transfer of voting rights is invalid in order to ensure that voting rights match residual claim rights and maintain the constraints on senior management represented by shareholder voting rights. The general prohibition of stock fights transfer in the articles of association blocks shareholders' right of withdrawal; this is not conducive to restraining potential abuses of power on the part of senior management and should be made invalid. Judges must differentiate between long- and short-term contracts and the initial and revised clauses of the articles of association in order to distinguish between the efficacy of different arrangements limiting transfer of stock rights as laid down in the articles of association. 展开更多

Generally,the field of fixed point theory has attracted the attention of researchers in different fields of science and engineering due to its use in proving the existence and uniqueness of solutions of real-world dynamic models.C^(∗)-algebra is being continually used to explain a physical system in quantum field theory and statistical mechanics and has subsequently become an important area of research.The concept of a C^(∗)-algebra-valued metric space was introduced in 2014 to generalize the concept of metric space.In fact,It is a generalization by replacing the set of real numbers with a C^(∗)-algebra.After that,this line of research continued,where several fixed point results have been obtained in the framework of C^(∗)-algebra valued metric,aswell as(more general)C^(∗)-algebra-valued b-metric spaces andC^(∗)-algebra-valued extended b-metric spaces.Very recently,based on the concept and properties of C^(∗)-algebras,we have studied the quasi-case of such spaces to give a more general notion of relaxing the triangular inequality in the asymmetric case.In this paper,we first introduce the concept of C^(∗)-algebra-valued quasi-controlledK-metric spaces and prove some fixed point theorems that remain valid in this setting.To support our main results,we also furnish some exampleswhichdemonstrate theutility of ourmainresult.Finally,as an application,we useour results to prove the existence and uniqueness of the solution to a nonlinear stochastic integral equation. 展开更多

As a consequence, million hectares of land exchanged hands. The ways the transfers happened combined with their geographic concentration in Sub-Saharian Africa, have earned the phenomenon the name of "land grab". The agricultural sector considered a "sunset industry" when commodities prices were declining, is now attractive to financial investors. These foreign investments may be good as they may improve agricultural productivity or instead bad as they may benefit only financial investors. Some results in terms of environmental and local communities' worsening conditions have already emerged. This paper aims to investigate what drives the big size transfers of land, to empirically estimate their effects in terms of local employment and to assess the environmental effects produced by the rapid transformation in the use of vast amount of land in terms of CO2 emissions. It is also proposed to use the estimation in terms of local employment impact as a way of distinguishing between foreign direct investment and land grabbing. 展开更多
