A Brief Analysis of the Non-commercial Forest Compensation System in China

The non-commercial forest is an important natural resource protecting the environment and contributing to the sustainable development of a nation. Due to its crucial positive external effects, it is inevitable policy that non-commercial forestry should be invested by government, thereby formulates the non-commercial forestry compensation system. This paper first discusses the theoretical basis of non-commercial forestry compensation system and the process of establishment of non-commercial forestry compensation system in China, and then analyzes the deficiency in the current compensation system.

Empirical Analysis of Factors Influencing Compensation for Non-commercial Forests under CVM

Based on non-commercial forests in Kunming City,this article conducts survey of 506 households in Kunming City to evaluate their willingness to pay ecological benefit of non-commercial forests,using Contingent Valuation Method(CVM);to analyze factors influencing their willingness to compensate for non-commercial forests,using multivariate statistical analysis method.The results show that income,educational level, housing ownership,outdoor exercise time,whether to be concerned about environmental problems,frequency of obtaining forest-related information monthly and whether understanding non-commercial forests or not,are the most principal factors influencing willingness to pay.

A Study on Compensation for Management and Protection Expenses of Non-commercial Forests

This paper analyzes the compensation nature of non-commercial forests under different ownership from two aspects, namely, whether the property right is limited and whether the management and protection expense has been incurred: there are no economic loss compensation problems caused by changes and limitation of property rights for the state-owned non-commercial forests with only the compensation on management and protection expense; but for the non-commercial forests owned by collectives or individuals, double compensation for both the economic loss and management expense exists because of limitation on the property right. In addition, an inframarginal economic analysis framework has been built for the management and protection compensation problems faced by non-commercial forests under different ownership in the perspective of the division of labor. Research results show that: the compensation standard for the management and protection expenses of non-commercial forests shall fall in between the "completely self-sufficient forestry economic structure U(Ayz)" and the "completely specialized productive structure of non-commercial forests U(B1)".

Comparison of Bacterial Cross-Contamination among Broiler Carcasses between Commercial and Non-Commercial Processed System and Its Public Health Implications

Objectives: This study aimed to conduct a comparative assessment of bacterial cross-contamination in commercial and non-commercial processing plants including associated risk factors for bacterial contamination. Study Design: This was analytic cross sectional survey on bacterial contamination of broiler carcasses between different processing systems. Introduction: Zambia, like most African and Asian Countries, still practices “live-open non-commercial broiler carcass processing systems” besides the “closed abattoir based systems”. However, shelf life, spoilage and hygiene levels have been postulated to vary based on the type of processing system. Live-open non-commercial processing systems are popular among majority consumers owing to their perceived “freshness”, compared to commercially dressed chickens. In between, consumers have to balance freshness and quality assurance. Ultimately, this becomes inert, remotely but an important public health issue. However, lack of empirical evidence on safety levels to guide consumer product selection leaves them to speculation. It is this need to close this gap that created an impetus for us to undertake this study. Methods: Biological samples were collected before carcass wash and after carcass wash alongside a structured questionnaire that gathered risk-associated data. Standard microbiological enumeration methods were used to isolate bacteria and enumerate contamination. Results: Broiler carcasses processed from “open” non-commercial systems were more contaminated (45.6%) than “closed-abattoir” commercially processed systems (35%). Escherichia coli were major contaminants (71.3%) and few Salmonella spices (typhi or para-typhi) in 1.3%. Risk analysis indicates washing (method) of carcasses at commercial systems was significantly more risky for contamination than non-commercial ones. Major sources of contamination were “distance from water sources”. Increased volume of slaughters per day (>15,000 birds) for commercial systems accounted for increased cross-contamination, particularly, distance from water source was a ma-jor risk factor for contamination.

Sponsor-investigator-relationship: challenges, recent regulatory developments and future legislative trends

Correct definition and management of sponsor- investigator relationship is of central importance for planing and executing clinical trials. During the last decade, there have been numerous modifications of guidelindes, international and national legislations and regulations. This implicated various alterations and shifts of essential responsibilities and tasks relating to the investigator, sponsor or sponsor-investigator what raised financial, clinical and ethical issues. First experiences with these new regulations and legislations are discussed together with international differences and their impacts on clinical trials. Regarding non-commercial trials and institutional sponsorship, there are still open organizational and legal questions after national implementation of the Europeam Clinical Trials Directive in 2004, although various approaches have been suggested in recent years in Europe. Current trends and controversies are discussed as well. A literature review was performed summarizing recent experiences with current legislations and risen controversies of these new legislations showing impact on future trends.
