Economic valuation can help management by clarifying the full range of benefits and costs of proposed management actions. In the past two decades, economic valuation of wetland ecosystem services has become one of the most significant scientific priorities for wetland protection. In this paper, we provide an overview of ecosystem services, and summarize the main interdisciplinary approaches to measure and value wetland ecosystem services. We identified four main methodological gaps preventing progress on wetland valuation of ecosystem services in China, which are: 1) confusion on terminology like intermediate and final ecosystem services, 2) lack of ecological production functions to link ecosystem characteristics to final ecosystem services, 3) static valuation making it difficult to evaluate the trade-offs and synergies among ecosystem services, and 4) lack of clear guidance on relating ecological compensation programs to conservation targets. Overcoming these gaps is important to inform wetland compensation mechanisms and conservation policies. We propose future research on wetland ecosystem services in China should be focused on: 1) defining final ecosystem services based on beneficiary preferences and underlying biophysical mechanisms, 2) establishing wetland monitoring programs at specific sites to collect data on final ecosystem service indicators and ecosystem characteristic metrics to create ecological production functions for economic valuation and rescaling techniques, and 3) incorporating wetland ecosystem service values into decision-making processes to inform wetland management.展开更多

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.展开更多

At this end it is important to develop performances control models and to identify appropriate results indicators, with the aim of introducing an effective doctors selection system for managerial roles. The paper considers the Italian situation and tests the current evaluation and selection methods, by analysing the literature and the existing legislation and by interviewing experts. Moreover, in order to reach an innovative model, complex organizations have been taken into account as benchmarks. Three different categories of experts have been interviewed and texted： national health care organizations managers, companies managers, and business consultants. The 137 interviewed experts have been asked about four main questions concerning the evaluation for hiring managers as chief medical director, department director, and head of complex units. The conducted research suggests four different options in order to evaluate and to select heads of complex unit for the most strategic roles. By consequence, the analysis shows that required characteristics must be managerial attitudes as well as clinical capabilities.展开更多

This would eventually lead to the final solution. However, the problem solution scenario is not so simple. Naturally, consumers＇ behaviors are difficult to be predicted and they do not always necessarily follow the rational-mind purchasing criteria. When purchasing food, mostly they choose the product because of its taste, quality and price, and lastly maybe due to its environmental friendliness from one hand. From the other hand, the manufacturer＇s priority is for the quantity sold and profit rather than product＇s environmental safety. Recently, is it possible to change consumers＇ mind-set and make them behave and select products in environmentally friendly manner？ The author thinks it＇s possible and the key is the kind of trigger through heart-moving incentive. This paper focuses on the Acorn Point System Project, which incorporates carbon foot print and carbon offset scheme, and argues about methods that can be used effectively and efficiently to facilitate those environmentally unmotivated companies and consumers to adopt environmentally friendly mind-set and shift to more proactive ones. This paper has confirmed that the most effective factors to stimulate unmotivated consumers to better acquire environmentally friendly mind-set, which leads to proactive eco-mind products purchasers and activists, are： （1） non-environmental product benefits must be stressed even for the environmentally friendly products; （2） environment consideration project incubation involves various interest parties and mechanism of shared satisfaction as a team; （3） start with small scale community project, which enables participants to recognize their project contribution.展开更多

Articles were assessed independently by two reviewers. Review Manager 5.1 was used fordata analysis.RESULTS: Fourteen randomized controlled experiments were included. Meta-analysis demonstrated that blood sugar levels and kidney weight to body weight ratios in the model group were higher than those in the normal group, and the curcumin group had significantly lower mesangial area to glomerular area ratios compared with the model group, and also lower levels of urinary protein,blood urea nitrogen and serum creatinine.CONCLUSION: Curcumin shows protective effects on the kidneys of rats/mice with diabetes.展开更多
