With the precondition of strictly controlling maximum emissions rights, initial water rights were allocated between the first and the second levels of the hierarchy in order to promote fair and coordinated development across different regions of the basin and coordinated and efficient water use across different water sectors, realize the maximum comprehensive benefits to the basin, promote the unity of quantity and quality of initial water rights allocation, and eliminate water conflict across different regions and water sectors. According to interactive decision-making theory, a principal-subordinate hierarchical interactive iterative algorithm based on the satisfaction degree was developed and used to solve the initial water rights allocation model. A case study verified the validity of the model.展开更多

This article differentiates and analyzes the relevant concepts about the ecological enviromnent, and puts forward the defined concept of the rights to the ecological environment water utilization. In addition, it points out the characteristic of those rights, and does elementary study on the allocation principle, methods, and steps on the rights.展开更多

Scholars from developing countries put forward the concept of equitable per capita cumulative emission rights. There are four possible operational definitions resulting from this concept. These potential options for allocation of emission rights are expressed with mathematical equations. Through simple simulation, this paper reveals the advantages, disadvantages and characteristics of each option.展开更多

The rational allocation of corporate control between different behavioral agents has attracted more and more attention. This paper points out that scholars have studied the allocation of corporate control from the angles of the agency cost theory, property rights theory, corporate finance theory, and the theory of corporate governance, which has great value. However, the existing theories also have some flaws on the allocation of corporate control. First, people still have different understandings and views over the meaning of corporate control. Secondly, the existing research theoretically only observes and studies an arrangement of sheer level control, the allocation between final control and real control. This paper argues to build the two-tier allocation of corporate control: The first tier relation is between ultimate control rights and actual control rights, the second tier relation is between indirect control rights and direct control rights which are in actual control rights. This study can explain the resource allocation effects of corporate control, promote the development and improvement of the theory of the firm.展开更多

Methods: Literature review on the relevant articles/material with the contents of the nurse’ s right of prescription home and a-broad. Semi-structured depth interview method was used to interview 18 experts on whether the nurses can participate in the graded nursing decision and whether nurses with certain ability can make the decision. Using the self-made questionnaire“Nur-ses involved in graded nursing decision-recognition questionnaire”, 553 nurses completed questionnaires on willingness to nurse decision-making grading. Using the analytic hierarchy process, the 23 experts’ judgment on the main body of the graded nurs-ing was rated. Using semi-structured depth interview method, 17 experts were interviewed on the graded nursing quality assess-ment and training outline. The form of expert personal judgment and the“grading nursing qualification experts predict question-naire”were used as a preliminary designing tool, 32 experts were asked to predict the graded nursing quality. The relatively im-portant factors that might promote implementation of right of Chinese nurse prescribing weights setting were obtained by analytic hierarchy process. Using Delphi method, 2 rounds of consultation to 291 experts/times were performed, and determined its con-tent on the fields of graded nursing decision, nurses’ job description, decision making nurse in graded nursing work process and related management system, decision-making main body of clinical nursing, nurse authority of prescription application qualifi-cation, clinical nurses, diabetes specialist nurses, tumor specialist nurses, nurses in emergency department, community nurses in certain circumstances writing prescription, and nursing undergraduate added with nurse authority of prescription related courses. Results: The physician is not considered to be the best decision-making main body of clinical nursing work and graded nurs-ing, nurses can participate in the work of decision-making. The qualification of hierarchical decision-making nurse and nurse prescribing applicants have been determined. The hierarchical nursing decision-making nurses’ position description and training outline have been compiled. Experts suggest that clinical nurses with certain qualifications should be given the rights of some prescription form ( independent prescription, prescription, prescription protocol extension) to prescribe specific drugs in high fe-ver, hypoglycemia, hypertension, anaphylactic shock and other 11 specific circumstances. The nurses of the diabetes should be given the right of prescribing sulfonylureas, biguanides, glucosidase inhibitor, and protamine zinc insulin, and the right to write the prescription and consultation for part of medical equipment, health education, and four routine tests, which contains blood sugar monitoring, urine glucose monitoring, glycosylated hemoglobin assay, and oral glucose tolerance test. Tumor specialist nurses should be given the right to write the prescription of 7 specific circumstances including blood routine tests, electrocardio-gram, blood biochemistry and other 9 laboratory tests, constipation, phlebitis, and cancer pain, and the right of 5 tumor emer-gency prescription including chemotherapy drug allergy, hemorrhagic shock, acute upper gastrointestinal bleeding. Nurses in e-mergency department with certain qualification should be given the right to prescribe specific drugs in 15 circumstances which include cardiac arrest, ventricular fibrillation, and acute cardiogenic chest pain. Community nurses with certain qualification should be given the right to write the prescriptions on 14 contents including disinfection and cleaning, sterile infusion type, and wound care products. Experts suggest that nursing undergraduate education in China should be added with 2 courses which are prescription rights related laws and regulations and nursing intervention, and that pharmacology course should be supplemented with related course in order to adapt to the implementation of nurse prescribing rights. Conclusions: China’ s nurses with certain qualification or after special training have the ability to accept and should be given the right of prescriptions in certain circumstance within the scope of their work.展开更多
