Although the existing legal norms and judicial practic-es can provide basic guidance for the right to personal data portabili-ty, it can be concluded that there are obstacles to the realization of this right through empirical research of the privacy policies of 66 mobile apps, such as whether they have stipulations on the right to personal data portability, whether they are able to derive copies of personal in-formation automatically, whether there are textual examples, whether ID verification is required, whether the copied documents are encrypt-ed, and whether the scope of personal information involved is consis-tent. This gap in practice, on the one hand, reflects the misunderstand-ing of the right to personal data portability, and on the other hand, is a result of the negative externalities, practical costs and technical lim-itations of the right to personal data portability. Based on rethinking the right to data portability, we can somehow solve practical problems concerning the right to personal data portability through multiple measures such as promoting the fulfillment of this right by legislation, optimizing technology-oriented operations, refining response process mechanisms, and enhancing system interoperability. 展开更多

Taking sample survey in the eighteen villages of Yunhe, Longquan and Qingyuan County of Lishui City of Zhejiang Province, the results show that the forest land transfer of sample peasants is mainly transfer-out, the private treaty of forest land transfer is the main pattern of most peasant households, forest right trading market hasn't got wide approval in peasants, peasants' dependence on land is reducing, and so on. Through analysis, the reasons of influent transfer of forest land include peasant's subjective will, less type of transfer objects, dull information communication, big difference of expected price and imperfect development of intermediary organization. In order to promote a healthy development of forest land transfer, the paper puts forward proposals of strengthening policy publicity, improving system, identifying property right, pushing variety of transfer types, developing forest land market, cultivating subject of market and so on. 展开更多

In order to comply with the needs of rural social and economic development,promote new industrialization,informatization,urbanization and agricultural modernization,and realize industrial transformation,the central government clearly puts forward that the traditional ' separation of two rights' mode of rural land( collectives have ownership and farmers have contracting management right) should be transformed into the ' separation of three rights' mode( collectives have ownership,farmers have contracting right,and operators have management right) to solve the problems of farmers’ financing difficulties and agricultural land abandonment,promote the moderate scale operation of agriculture,and improve land use efficiency. It is found that the following points should be noted in the later stage of realizing the ' separation of three rights' of rural land. Firstly,the transfer of farmland management right in the process of realizing the ' separation of three rights' faces market risk,system design flaws,policy coordination failures and other problems. Secondly,the impact of implementation of ' separation of three rights' on rural and social development should also be noted. 展开更多

Using comparative analysis and documentation method,this paper reveals infeasibility of establishing land development rights in China based on the path of real rights,in the hope of providing recommendations for improving the research route on localization of land development rights. Results indicate that at the level of legislative techniques,the land development rights rooted from property right paradigm do not contain possess the elements of object of real rights and conflict with the principle of statutory real rights and single ownership. At the level of legal logic,individual case of TDR conflicts with real right in rem. In conclusion,it is infeasible to introduce land development rights based on the path of real rights. In future,it is required to discard the concept of mechanical transplantation and explore feasible path and seek feasible way for establishing land development rights along with the direction of quasi-property and improving regulation efficiency. 展开更多

The purpose of this paper is to study the energy efficiency of a local living space exposed to solar radiation in the subtropical climate of Casablanca. The study was mainly focused on the contribution of a phase change material (PCM), inserted into a 7-cm thick air layer of a double brick wall, in two different locations. We note that the experimental study was conducted using two real-scale test cavities, located in the Faculty of Science Ain Chock-Casablanca. Two PCM mounting methods were used for the south and west walls, in order to test its energy efficiency as a storage and retrieval means of the solar flux coming from the outside. In the case of the southern wall, the PCM is put directly on the internal side of the outside part of the double wall (Case 1). For the west wall, the PCM is placed 1.2 cm away from the internal side of the outer part of the double wall (Case 2). The first result shows that the PCM placed to the wall allows storing the solar heat during the day and releasing it to the outside of the building at night. While in the second case, the PCM keeps the heat stored day and night. 展开更多

Efficient real time data exchange over the Internet plays a crucial role in the successful application of web-based systems. In this paper, a data transfer mechanism over the Internet is proposed for real time web based applications. The mechanism incorporates the eXtensible Markup Language (XML) and Hierarchical Data Format (HDF) to provide a flexible and efficient data format. Heterogeneous transfer data is classified into light and heavy data, which are stored using XML and HDF respectively; the HDF data format is then mapped to Java Document Object Model (JDOM) objects in XML in the Java environment. These JDOM data objects are sent across computer networks with the support of the Java Remote Method Invocation (RMI) data transfer infrastructure. Client's defined data priority levels are implemented in RMI, which guides a server to transfer data objects at different priorities. A remote monitoring system for an industrial reactor process simulator is used as a case study to illustrate the proposed data transfer mechanism. 展开更多

Since mining rights of coal resources(for short MRCR) could be regarded as a multi-stage compound real option,the evaluation for MRCR can be better solved using op- tion theory than the NPV.In the former research,we developed a two-factor model of evaluating MRCR when the coal spot price and convenience yield are stochastic based on option theory.On the basis of this two-factor model,we set up a three-factor model of evaluating MRCR when the interest rate followed a stochastic process.Through a real example application,we found the model can get higher values than the two-factor model and the NPV.This is because considering the volatility of interest rate can improve the executive opportunity of MRCR. 展开更多

China has started shifting from relying on supply management to demand management strategy in addressing its water shortage problems.Water option,a financial derivative for water commodity,has been utilized to manage water demands in the United States and Europe since the 1990 s but is still novel to China.In this study we analyzed the pros and cons of China’s existing system for water rights transfers and proposed an alternative,flexible trading instrument-water options for China.Incorporating the uncertainty to water option pricing,this study first conducted an empirical analysis of the water option in the water-receiving area of the Hanjiang-Weihe River Transfer Project of China,and then evaluated the benefits of the water option applications.Results show that water option trading can bring water cost saving and increase the potential industrially added value for industrial enterprises in the receiving area,and trading of short-and-medium term water options is more favorable than the long-term water options trading.The novel water option trading proposed in this study,once verified through pilot studies,will be helpful in addressing water shortage problems in China. 展开更多

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. 展开更多

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. 展开更多

Taking Shuangliu County,Chengdu City,China as an example,evaluation index system for the rights protection effects of farmland transfer is established contract from three aspects of basic information,transfer agreement and legal safeguards in the contracts.According to the investigation data,weight of evaluation index is determined by both entropy weight and Analytic Hierarchy Process.Comprehensive index method is used to evaluate the rights protection effects of farmland transfer contract in the flat dam,high hill and low hill in Shuangliu County,Chengdu,China.Result shows that the transfer agreement of farmland and the basic information of contract greatly affect the rights protection effects of farmland transfer contract.There are differences in the five indices of the information of the signature of contract,pricing for payment,time limit for farmland transfer,transfer mode of farmland,and use range of farmland transfer.During the farmland transfer in reality,there are three hidden dangers in farmer's land rights and interests,which are the ill-formed transfer behavior,the relatively low income of farmers from farmland transfer,and the quality decline of farmland and difficult full reclamation in transfer period.Based on the evaluation result and investigation data,countermeasures are put forward to improve the rights protection effects of farmland transfer contract. 展开更多

The optimal plane for measurement of the right ventricular (RV) volumes by real-time three-dimensional echocardiography (RT3DE) was determined and the feasibility and accuracy of RT3DE in studying RV systolic function was assessed. RV “Full volume” images were acquired by RT3DE in 22 healthy subjects. RV end-diastolic volumes (RVEDV) and end-systolic volumes (RVESV) were outlined using apical biplane, 4-plane, 8-plane, 16-plane offline separately. RVSV and RVEF were calculated. Meanwhile tricuspid annual systolic excursion (TASE) was measured by M-mode echo. LVSV was outlined by 2-D echo according to the biplane Simpson's rule. The results showed: (1) There was a good correlation between RVSV measured from series planes and LVSV from 2-D echo (r=0.73; r=0.69; r=0.63; r=0.66, P<0.25—0.0025); (2) There were significant differences between RVEDV in biplane and those in 4-, 8-, 16-plane (P<0.001). There was also difference between RV volume in 4-plane and that in 8-plane (P<0.05), but there was no significant difference between RV volume in 8-plane and that in 16-plane (P>0.05); (3) Inter-observers and intro-observers variability analysis showed that there were close agreements and relations for RV volumes (r=0.986, P<0.001; r=0.93, P<0.001); (4) There was a significantly positive correlation of TASE to RVSV and RVEF from RT3DE (r=0.83; r=0.90). So RV volume measures with RT3DE are rapid, accurate and reproducible. In view of RV's complex shape, apical 8-plane method is better in clinical use. It may allow early detection of RV systolic function. 展开更多

The dynamic characteristics of the area of the atrial septal defect(ASD) were evaluated using the technique of real-time three-dimensional echocardiography(RT 3DE), the potential factors responsible for the dynamic characteristics of the area of ASD were observed, and the overall and local volume and functions of the patients with ASD were measured. RT 3DE was performed on the 27 normal controls and 28 patients with ASD. Based on the three-dimensional data workstations, the area of ASD was measured at P wave vertex, R wave vertex, T wave starting point, and T wave terminal point and in the T-P section. The right atrial volume in the same time phase of the cardiac cycle and the motion displacement distance of the tricuspid annulus in the corresponding period were measured. The measured value of the area of ASD was analyzed. The changes in the right atrial volume and the motion displacement distance of the tricuspid annulus in the normal control group and the ASD group were compared. The right ventricular ejection fractions in the normal control group and the ASD group were compared using the RT 3DE long-axis eight-plane(LA 8-plane) method. Real-time three-dimensional volume imaging was performed in the normal control group and ASD group(n=30). The right ventricular inflow tract, outflow tract, cardiac apex muscular trabecula dilatation, end-systolic volume, overall dilatation, end-systolic volume, and appropriate local and overall ejection fractions in both two groups were measured with the four-dimensional right ventricular quantitative analysis method(4D RVQ) and compared. The overall right ventricular volume and the ejection fraction measured by the LA 8-plane method and 4D RVQ were subjected to a related analysis. Dynamic changes occurred to the area of ASD in the cardiac cycle. The rules for dynamic changes in the area of ASD and the rules for changes in the right atrial volume in the cardiac cycle were consistent. The maximum value of the changes in the right atrial volume occurred in the end-systolic period when the peak of the curve appeared. The minimum value of the changes occurred in the end-systolic period and was located at the lowest point of the volume variation curve. The area variation curve for ASD and the motion variation curve for the tricuspid annulus in the cardiac cycle were the same. The displacement of the tricuspid annulus exhibited directionality. The measured values of the area of ASD at P wave vertex, R wave vertex, T wave starting point, T wave terminal point and in the T-P section were properly correlated with the right atrial volume(P〈0.001). The area of ASD and the motion displacement distance of the tricuspid annulus were negatively correlated(P〈0.05). The right atrial volumes in the ASD group in the cardiac cycle in various time phases increased significantly as compared with those in the normal control group(P=0.0001). The motion displacement distance of the tricuspid annulus decreased significantly in the ASD group as compared with that in the normal control group(P=0.043). The right ventricular ejection fraction in the ASD group was lower than that in the normal control group(P=0.032). The ejection fraction of the cardiac apex trabecula of the ASD patients was significantly lower than the ejection fractions of the right ventricular outflow tract and inflow tract and overall ejection fraction. The difference was statistically significant(P=0.005). The right ventricular local and overall dilatation and end-systolic volumes in the ASD group increased significantly as compared with those in the normal control group(P=0.031). The a RVEF and the overall ejection fraction decreased in the ASD group as compared with those in the normal control group(P=0.0005). The dynamic changes in the area of ASD and the motion curves for the right atrial volume and tricuspid annulus have the same dynamic characteristics. RT 3DE can be used to accurately evaluate the local and overall volume and functions of the right ventricle. The local and overall volume loads of the right ventricle in the ASD patients increase significantly as compared with those of the normal people. The right ventricular cardiac apex and the overall systolic function decrease. 展开更多

Existing laws have three limitations on transfer of land contractual management right. The survey of 506 farmer households in Zhejiang,Jiangxi and Guangxi provinces indicates that most farmers have the consistent knowledge of limitation on " transfer being approved by the party giving out the contract in advance" with legislative requirements,but it is not effectively implemented in actual operation. As to limitation on transferee,no matter in cognition of farmers,or in real transfer process,the transferee is not totally limited to farmers engaged in agricultural production and management. For the constraint that the transferor should have stable non-agricultural occupation or stable income source, most farmers agree,but more than half of the farmers have not confirmed the transfer action in practice. 展开更多
