First-Principle Study on the Electronic Structure and Optical Property of New Diluted Magnetic Semiconductor(Y_(0.75)Ca_(0.25))(Cu_(0.75)Mn_(0.25))SO

The band structure,DOSs,and optical properties of(Y_(0.75)Ca_(0.25))(Cu_(0.75)Mn_(0.25))SO,including dielectric function,absorption function,reflection function,and energy loss spectrum were studied by using the first-principles calculation.The calculation results indicate that(Y_(0.75)Ca_(0.25))(Cu_(0.75)Mn_(0.25))SO is a direct bandgap semiconductor with a bandgap of 1.1 eV.The Fermi surface is asymmetric and exhibits spin splitting phenomenon.The new type of dilute magnetic semiconductor(Y_(0.75)Ca_(0.25))(Cu_(0.75)Mn_(0.25))SO exhibits significant light loss around 70 eV,with light reflection gradually increasing after 30 eV,and light absorption mainly occurring around 8-30 eV.These results also provide a basis for the discovery of more types of 1111 phase new dilute magnetic semiconductors in the future.

Non‑fungible tokens:a bubble or the end of an era of intellectual property rights

The viability of exponentially growing non-fungible token(NFT)market is evaluated by identifying potential value-generating mechanisms that can be rationalized.After identifying the value-generating mechanisms underlying the positive values of NFTs,this study establishes a pricing model for NFTs that follows a continuous-time financial framework.As NFTs are claimed to securitize“ownership rights short of use”,and as such they may potentially serve as a substitute for the need to rely replace the reliance on the legal protection provided by intellectual property rights(IPRs).Considering this issue,this study evaluates the likelihood that NFTs will replace existing mechanisms that protect producers’rightful claim to use their assets or the need to apply the legal code that governs IPRs.The financial condition for this potential shift is derived for a category of assets whose use or consumption does not reduce supply as the notion of scarcity does not apply.

Impacts of Changes in Structure of Rural Land Property Rights on Agricultural Performance

In the reform process of the rural land property rights system,the incentive mechanism of the rural land property rights system has a crucial impact on the production activities of rural economic entities.Due to the different rights structures of the property rights system in different social and economic development stages,the land rights and interests enjoyed by rural economic subjects are different,and the degree of incentives for farmers is also different.This difference in incentives affects farmers investment in agricultural production factors,which in turn affects agricultural performance.This paper analyzes the incentive impacts of the structure of rural land property rights on the changes of farmers land rights and agricultural performance since the founding of the People s Republic of China,in order to further deepen the reform of the land system,protect the rights and interests of farmers,promote the modernization of agriculture and rural areas,and explore the realization form and operation mechanism of the rural collective land system in the new era.

Reform Paths of Rural Land Property Rights System in the Context of Agricultural Modernization

The reform of rural land property rights system can promote large-scale and intensive agricultural production,improve the quality of laborers,improve agricultural production efficiency,increase farmers'income,and effectively promote the development of agricultural modernization.In the context of the reform of the"separation of three powers",the rural land property rights system still has problems in terms of ownership,use rights,disposal rights,and income rights,which affect the healthy development of agricultural modernization.In this situation,it is necessary to further clarify the subject of rural land ownership,thoroughly improve the right to use rural land,vigorously improve the right to dispose of rural land,effectively protect the right to benefit from rural land,and deeply promote the reform of the rural land property rights system in order to effectively promote the development of agricultural modernization.

The Conflict and Balance Between Intellectual Property Rights and Public Freedom of Information in the“Anti-circumvention Clause”

There is a long-standing conflict between intellectual property rights and public freedom of information.The continuous development of the“anti-circumvention clause”has caused the conflict to intensify.As a basic human right,freedom of information is being gradually eroded by the expansion of intellectual property rights.The existing research mainly carries on the right balance from the negative protection path,but the positive protection path is more advantageous to realizing the public freedom of information and alleviates the conflict between the two kinds of rights.In practice,there are some problems in the application of the anti-circumvention clause,such as the legality of the aim,the division of the protected part,and the determination of the circumvention.This is mainly due to the lack of restrictions on technical measures,the failure to distinguish between“copyright protection”and“contact control”,and the offside and absence of administrative bodies in practice.We should protect public freedom of information by distinguishing the two measures of copyright protection and contact control and the two torts of access and use,increasing the restrictive conditions for the use of technical protection measures,and changing the functions of administrative supervision agencies.

Critical behaviours and magnetic properties of three-dimensional bond and anisotropy dilution Blume-Capel model in the presence of an applied field

This paper studies the critical behaviours and magnetic properties of three-dimensional bond and anisotropy dilution Blume-Capel model （BCM） in the presence of an applied field within the effective field theory. The trajectory of tricritical point, reentrant transitions and degenerate patterns of anisotropy are obtained both for the bond and the anisotropy dilutions. The global phase diagrams demonstrate unusually reentrant phenomena. The temperature dependences of magnetization curves undergo remarkable spin glass behaviour at low temperatures, and transform from ferromagnetism to paramagnetism at high temperature in applied fields. Temperature dependence of magnetic susceptibility curve is in qualitative agreement with experimental result.

The Impact of Changes of Property Rights on Farmland Use:An Empirical Study of China during Transition

In China, farmland property rights characterized by the household-responsibility system (HRS) have been improved since the reform and opening-up. The rights of use, transfer and gain become more stable, authorized and complete. This paper firstly analyzes the impact on farmland productivity, which comes from the improvement of farmland property rights. Then, an economet- ric model is built to test the above analysis. It concludes that changes of property rights will affect farmland performance in China. In the end, some policy implications are explored for fur- ther reforms.

Effect of Dilution of Treated Distillery Effluent (TDE) on Soil Properties and Yield of Sugarcane

Sugarcane is one of the most important cash crops, which plays a pivotal role in India’s agricultural and industrial economy. The treated distillery effluent (TDE) being plant originated, contains all plant nutrients and organic matter. Therefore, it is being used as a cheap source of nutrients and organic manure in agriculture activities in soil besides improving soil physical properties. The experiment was conducted during August, 2010-2011 and 2011-2012 with CO 86032 in a randomized block design with six treatments and was replicated four times. The TDE was discharged @ 1.00, 0.50, 0.33, 0.25 and 0.20 lakh liters·ha-1 to get the dilutions of 1:10, 1:20, 1:30, 1:40 and 1:50 dilutions respectively. It was applied four times at 40 days interval starting from 45th day after planting. The fertilizers viz., N and P @ 75 percent of the recommended dose were applied and K was skipped. The results revealed that irrigation with TDE at 1:10 dilution resulted in higher yield of sugarcane. The TDE did not have any influence on quality parameters of sugarcane. The TDE application favourably influenced the available nutrients and organic carbon content in the soil. Besides, the present findings credibly proved that the TDE application not only enhanced the soil fertility status but also substituted for 25 percent of N and P and 100 percent of K fertilizers to sugarcane crop.

The Innovation and Plights of Farmland Property Rights System Reform in Chongqing Municipality

Based on the background of national urban and rural comprehensive reform pilot area and the introduction of the profiles of research region and the data obtained by on-the-spot interview survey,the innovative models of farmland property rights system reform in Chongqing are introduced by applying participatory rural appraisal methods and examples. The innovative models cover buying shares of contract management rights,transforming from farmers to townspeople and mortgaging contract management rights. The plights exist in the reform are analyzed,among which the plights of buying shares of contract management rights are introduced from the following five aspects:the conflict with the present land contract laws,the possible new round of massive scale land loses,the confounded functions of government and enterprise caused by risk transference and the difficulties of handling assets when the contract management rights expired. Besides,the plights of the transforming from rural residents to urban residents are analyzed from four aspects,which include the particularity of reform,high financial pressure,emergence of interbedded people and difficulties of payoff of village-based companies. From the facets of limited mortgage area,risks of reimbursing the loan,legal risks of mortgage. The results show that the stock purchasing model of contractual management rights reveals the capital value of land and the model is of theoretical and practical significance in law and economics. However,the social security system is not perfect,so the stock purchasing model of contractual management rights can not be expanded. In addition,the participation of more famers and the expansion of enterprises are limited as well. The land comprehensive reform model of transforming from rural residents to urban residents is of positive significance to the comprehensive exploration of farmland property system reform,but this kind of model should be supported by strong economy. The stock purchasing model of contractual management rights is of significance to perfect the contractual management rights,but it conflicts with the existing laws and financial systems.

Unit Environmental Property Rights: Efficiency, Responsibility and System

The inexplicit efficiency of environmental property rights lies in its fuzziness. Based on the character of environmental property rights discussed, unit environment shows intra relationship between efficiency and duty of environmental property rights, and constructs a symmetrical system arrangement. Through analyzing the possibility and feasibility of unit environmental property rights, the significance of symmetrical system arrangement to avoid the inexplicit efficiency of environmental property rights is discussed in this dissertation from the aspect of the validity of offering and implementing system.

Justification and System Arrangement of Virtual Property Rights——Comments on Article No. 127 of General Provisions of the Civil Law

In the process of formulating the General Provisions of the Civil Law of P. R. China, the attribute of virtual property rights has changed from real rights to non-real rights. Article No. 127 thereof does not clarify the nature of virtual property rights after all, and the place where virtual property is put in the "Civil Rights" chapter of General Provisions of the Civil Law makes the concept even more complex and confusing. The "relationships paradigm" protection of virtual property does not have a definite classification criterion, nor stands opposite to the "rights paradigm." There are two different ways to justify the "theory of virtual property as a real right" under the "rights paradigm" protection, namely, essentialism and consequentialism. The former resulted from utilizing features in a demonstration and identifying disposal rights with real rights, while the latter resulted from adherence to the dichotomy system of property rights comprising real rights and creditor's rights. From the perspective of larceny in Criminal Law and virtual property insurance in The Social Insurance Law, the attribute of virtual property rights is irrelevant to creditor's rights. The attribute of virtual property rights shall be defined as virtual property rights so that it can be included in the system of civil rights. The uniqueness of virtual property is enough to become an object of emerging civil rights; intangible property rights as a superordinate theoretical concept cannot reflect the essence of virtual property rights. The legislative frame of virtual property rights shall be comprised of the subject, object, exercise, publication and change of the rights.

Ferrimagnetic Properties of Bond Dilution Mixed Blume-Capel Model with Random Single-Ion Anisotropy

We study the ferrimagnetic properties of spin 1/2 and spin-1 systems by means of the effective field theory. The system is considered in the framework of bond dilution mixed Blume-Capel mode/ （BCM） with random single-ion anisotropy. The investigation of phase diagrams and magnetization curves indicates the existence of induced magnetic ordering and single or multi-compensation points. Special emphasis is placed on the influence of bond dilution and random single-ion anisotropy on normal or induced magnetic ordering states and single or multi-compensation points. Normal magnetic ordering states take on new phase diagrams with increasing randomness （bond and anisotropy）, while anisotropy induced magnetic ordering states are always occurrence no matter whether concentration of anisotropy is large or small. Existence and disappearance of compensation points rely strongly on bond dilution and random singleion anisotropy. Some results have not been revealed in previous papers and predicted by Néel theory of ferrimagnetism.

Orbital Dilution Effect on Structural and Magnetic Properties of Fe1-xMnxV2O4

Structural and magnetic properties are investigated for Fe1-xMnxV2O4 （0≤ x ≤ 1） spinels. As orbital-active Fe^2＋ is substituted with Mn^2＋, the cubie-to-tetragonM transition TsI and the tetragonal-to-orthorhombic transition Ts2 gradually decrease. These structural transitions originate from the Fe^2＋ ferro-orbital order （F-OO）. Below Yafet-Kittel （YK） magnetic transition TN2, V^3＋ orbital order （V-OO） plays an important role on global structure. Here x = 0.6 is a critical point. Fe^2＋ F-OO and V^3＋ F-OO coexist for 0 ≤ x ≤ 0.5. For x≥ 0.6, the orbital pattern of V^3＋ is antiferro （AF）-00, and Fe^2＋ F-OO disappears. Structural transition Ts3, accompanied by YK magnetic transition TN2, decreases initially, and then increases at x = 0.6. A scenario for the complex phase diagram arising from the cooperation or competition of Fe^2＋ and V^3＋ orbitals is proposed.

Game of Property Rights and System Change

Governments＇ protection and support are very important for rural enterprises during their birth and development. But, in fact, governments own the rights to control the operation of rural enterprises to a large extent. Govemments encourage and lead the reform of property rights of rural enterprises. Why governments are willing to give up vested interests, and actively promote the reform of property rights of rural enterprises？ This seems to be the key to explain the reform of property rights of rural enterprises. This paper puts forward the hypothesis, uses mathematical models and statistical analyses, and adopts relevant data to verify the needs of governments for fiscal targets, and the rationality of their behavior actively encourages and promotes reconstruction during the reform for maximizing their interests.

Property Rights, Institutions and Forest Resources Management in Developing Countries

The objective of this paper is to propose a conceptual framework stimulating the sustainable management of natural resources in Central Africa. Based on the forest resources, we show how good identification and allocation of property rights strengthen the joint management of forest resources. Cameroon is selected as an example, since the country represents one of the most forest-intense areas in Africa. In doing so, we first evaluate the performance of institutions in fostering sustainable forest management. Second we show how good elaboration and allocation of property rights may contribute to improving efficiency in forest management. Using the New Institutional Economic (NIE) theory we provide an outline of the potential relationships between forest management and property rights allocated to stakeholders involved in forest exploitation. Finally we provide two forms of institutional structures that could improve forest management efficiency: public-private partnership and multi-stakeholder management approaches. Public-private partnerships are joint project management processes operated by both private businesses and public entities in order to combine public prescriptive mechanisms with private operational roles. Multi-stakeholder management approach is also a co-management initiative combining public entities, private actors and local population to increase the involvement of local dwellers living in forest areas in the decision process.

Timberland Investing and Private Property Rights in the United States of America

Investments in rural land for agriculture, timber, and other natural resource purposes occur frequently and globally. Fundamental principles of liberty and property found in the United States of America’s (“US”) legal system, from its origins to recent US Supreme Court decisions, continue to positively benefit holders of real estate in the Southern US, through a deep-rooted public policy of supporting private property rights and rural economic development. This stable rule of law enhances the long-term adaptability and sustainability of timberland as an asset class. This article is a commentary. It combines legal research methodology with the observations and conclusions of the authors. Its purpose is to demonstrate that the existence of alienable, documentable ownership, and related property rights create inherent stability and security. These principles form the basis of a culture that is defined by the rule of law and is “open for business.” This business mindset is particularly prevalent in the Southern US.

Regulation or Property Rights： The Effect of China＇s Coal Mine Shutdown Policy on Work Safety

Since 1999, shutdown policy has been one of the most important industrial policies in China ＇S coal mining industry. There have been many controversies surrounding this policy and its effect on coal mine safety. This paper summarizes, analyzes and tests two contradicting views of the effects of shutdown policy on the mortality rate of township-and-village-owned coal mines. One view, or the regulative view, believes that shutdown policy induces firms to increase safety input, thus decreasing mortality. The opposing view, or the property rights view, argues that shutdown policy disturbs property rights stability and actually increases mortality. We built a simple theoretical model to analyze these contrasting rationales. The model uses the difference-in-difference method and provincial panel data from 1995 to 2005 to empirically test the policy＇s effects. Our findings are that shutdown policy significantly decreases output while also increasing mortality in township-and-village coal mines. This result is consistent with the property rights view.

The Establishment of Intellectual Property Rights

A common act taken by every innovation-oriented country is its protection for intellectual property. The main mission for establishing intellectual property rights is to normalize the rights and laws over its entire domain of jurisdiction. This article introduces the new concept of "intellectual-property-rights-ization", and discusses about the role and importance of this concept; a country that has normalized intellectual property rights are characterized by a people that realize the importance of intellectual property rights, a presence of a rule system that protects one 's intellectual property, an administration that regulates intellectual property rights, a specialization of labor in protecting IPR, and a strong education system.
