A two-step approach to investigate the effect of rating curve uncertainty in the Elbe decision support system

For river basin management, the reliability of the rating curves mainly depends on the accuracy and time period of the observed discharge and water level data. In the Elbe decision support system (DSS), the rating curves are combined with the HEC-6 model to investigate the effects of river engineering measures on the Elbe River system. In such situations, the uncertainty originating from the HEC-6 model is of significant importance for the reliability of the rating curves and the corresponding DSS results. This paper proposes a two-step approach to analyze the uncertainty in the rating curves and propagate it into the Elbe DSS: analytic method and Latin Hypercube simulation. Via this approach the uncertainty and sensitivity of model outputs to input parameters are successfully investigated. The results show that the proposed approach is very efficient in investigating the effect of uncertainty and can play an important role in improving decision-making under uncertainty.

The obstacles and countermeasures of developing function of China＇s Unemployment insurance funds

The function of the unemployment insurance funds arc： ensuring the basic life and stabling employment, preventing unemployment and promoting employment, on the one hand, it guarantee basic livings of the unemploycd, in order to reduce the impact on the individual and society. On the other hand, it also has a function of stabling employment, preventing unemployment and promoting unemployed again obtain employment. In recent years, however, the unemployment insurance fund revenue has been greater than its expenditure, balance funds become more and more, it not only faces a risk of depreciation, also will cause the waste of funds. Therefore, improve the utilization rate of the uncmployment insurance fund itself and expand the function of the unemployment insurance fund, realize the sustainable development of unemployment insurance funds is great significance.

Costing and Pricing in Healthcare Private Firms

This article analyzes the development of an activity-based costing （ABC） system in a private Italian healthcare firm. Findings shed light on the role of the cost accounting system in price assessment： It outlines new opportunities for the identification of the service mix offered as well as for price optimization. Because private companies provide services both within the public system--where the National Health System （NHS） provides fixed reimbursement fees--and within the private system--where prices are defined by each company. Accurate cost information is extremely important to support managers in the analysis of the service mix profitability offered in each system. For the business segment in which companies do not have flexibility in setting prices, cost information enables managers to identify services which may present profitability problems. For the business segment where price flexibility exists, cost information supports the identification of pricing errors so that charges can be better defined.

Genetic Stability of Cryopreserved Grapevine （Wtis vinifera L.） Genome by Vitrification Method

Grapevine （Vitis spp.） is an economically important fruit crop worldwide. In Mexico, Sonora State leads the table grape production and exportation to international markets. In this regard, it is important to preserve the grape varieties during long time without phenotypical or genotypical changes. Cryopreservation is a good alternative, although it very often can induce changes in genome and phenotype. In this study, grapevine cv. ＂Flame Seedless＂ axillary buds were cryoprcserved by vitrification using the plant vitrification solution 2 （PVS2） and stored in liquid nitrogen （LN） for one hour, one week and one month, respectively. Genetic stability of buds cryopreserved under all treatments was evaluated using inter-simple sequence repeats （ISSR） markers. Ten ISSR primers were evaluated, but only two primers were possible to amplify distinct and reproducible bands with sizes between 300 bp and 2,000 bp. Different ISSR fragment patterns were recorded in cryopreserved buds as compared with control. These results suggest that cryopreservation by LN and vitrification-cryopreservation affect genetic stability in grapevine.

Noether Symmetry and Conserved Quantities of Fractional Birkhoffian System in Terms of Herglotz Variational Problem

The aim of this paper is to study the Herglotz variational principle of the fractional Birkhoffian system and its Noether symmetry and conserved quantities. First, the fractional Pfaff-Herglotz action and the fractional PfaffHerglotz principle are presented. Second, based on different definitions of fractional derivatives, four kinds of fractional Birkhoff’s equations in terms of the Herglotz variational principle are established. Further, the definition and criterion of Noether symmetry of the fractional Birkhoffian system in terms of the Herglotz variational problem are given. According to the relationship between the symmetry and the conserved quantities, the Noether’s theorems within four different fractional derivatives are derived, which can reduce to the Noether’s theorem of the Birkhoffian system in terms of the Herglotz variational principle under the classical conditions. As applications of the Noether’s t heorems of the fractional Birkhoffian system in terms of the Herglotz variational principle, an example is given at the end of this paper.
