On the basis of the empirical investigation of countryside in Sichuan Province, the offside and vacancy of the administration of the "two committees in village" in the villagers′ autonomy are studied tentatively. The results show that the offside and vacancy of the "two committees in village" can be divided into three types, covering the village party branch-dominated, the villagers′ committee-dominated type and the antagonism of the two village committees. The reasons for the offside and vacancy of administration of the "two committees in village" are analyzed, including the fragility of the two committees of the village; the imbalanced power sources of the two committees of the village; the imbalance of the competition for interests of the two committees and the negative effects of traditional politics and culture. The countermeasures are put forward, for example, reinforcing the system construction of rural grassroots organizations; expanding the democratic election modes such as "two-vote system " and "selecting one from the two recommended"; establishing the coordinative and supervisory mechanisms between the two committees in the village and introducing into college-graduate village officials to improve the quality of rural cadres.展开更多

The California’s cap-and-trade program (California’s carbon market hereafter) allows forestland owners from any part of the contiguous United States to supply carbon credits to compliance entities. In this study, we estimate South Carolina (SC) private forestland owners’willingness to accept compensations to participate in the California’s carbon market using a contingent valuation method. Results: We estimate forestland owners’mean willingness to accept as$67 per acre per year. Our results reveal higher probability of participation of forestland owners with interests in preserving forest ecosystems than those who do not. Additionally, forestland owners who trust in information about climate change from scientists or government are willing to participate more than those who do not. Conclusions: Various factors hinder landowners’ability to participate in carbon markets. Forestland owners in SC consider legislative uncertainty and long-time commitment as the main barriers to participation in California’s carbon market. From this research, average forestland tenure in SC is 27 years, which is far less than the 100-year time commitment of the California’s carbon market. Of those who agreed to participate, choosing between adopting and not adopting any of the three main forest management practices in the California’s carbon market:28% are likely to adopt improved forest management (IFM) practices, 24% are likely to adopt reforestation due to understocked forestlands, and 14% are likely to adopt avoided conversion. In another development, the concept of aggregation has dominated discussions in the California’s carbon market of late. It is an advocacy to include small-scale forestlands in the California’s carbon market. To aggregate, different forestland owners will combine their forestlands to participate. We find that 79% of SC forestland owners are willing to aggregate to participate. However, this research is unable to determine how much total forestland is available in SC for carbon market. We recommend future research in the State on forestland owners’participation in carbon market should consider evaluating forestland availability.展开更多

The enrolled patients were divided into?ⅠB and?ⅡA groups based on tumor size according to the 8^(th) edition AJCC criteria. Clinical characteristics, including age, gender, race, tumor size, primary site, and grade were summarized. Univariate and multivariate analyses were performed to explore the prognostic factors of the?ⅠB and?ⅡA stages of pancreatic cancer under new criteria.RESULTS A total of 1349 pancreatic cancer patients were included. More patients had stage?ⅠB rather than stage?ⅡA. Stage?ⅠB tumors(54.85%) were mainly located in the head of the pancreas, while stage?ⅡA tumors were more often located in the tail and head of the pancreas(35.21% and 31.75%, respectively). The survival time of stage?ⅠB and?ⅡA patients had no significant difference. Univariate and multivariate analyses indicated that the prognostic factors of survival for stage?ⅠB and?ⅡA patients were different. for stage?ⅠB patients, age and primary site were the independent prognostic factors; for stage?ⅡA patients, age and grade were the independent prognostic factors. The risk of death was lower among patients aged ≤ 65 years than those aged > 65 years.CONCLUSION The prognostic factors for stage?ⅠB and?ⅡA patients are different, but age is the independent prognostic factor for all patients. The survival time of stage?ⅠB and?ⅡA patients has no significant difference.展开更多

It involves the management of competing vegetation necessary to obtain the high yields expected in modern forest plantations via control of interfering plants that influence regeneration outcome, impact timber stand development, and limit native plant and wildlife diversity. It includes cultural control, fire control, mechanical control, biological control, and chemical control. The public perception of forest vegetation management, especially chemical control, is sometimes negative due to health and environmental concerns. It is an important tool in the forest management alternatives available to consulting foresters managing family forest lands (the vast majority of private forest land in the United States). We report on a study that addresses the motivations of family forest owners that implement forest vegetation management practices and the motivation of those who chose not to implement after forester recommendations to do so. For those who do implement forest vegetation management, improvement of wildlife habitat and increased timber growth was the main motivation. For those who did not, cost was the main concern. Size of forest holding plays a major role in determining who will practice intensive forestry.展开更多

Infection with the parasite in human causes toxoplasmosis that may pose a high risk in immunocompromised individuals under certain clinical conditions. Cats are the ultimate hosts of <i>T. gondii</i> where oocysts are formed through mating of male and female gametes. Infected cats can expel <i>T. gondii</i> oocysts in their feces, and thereby capable of pass on a disease to humans and other animals through consumption of foods, vegetables and water that are polluted with cat feces. The study was conducted to detect the presence of anti-<i>T. gondii</i> IgM and IgG antibodies in the blood of individuals with or without cat contact to determine if there is any relationship between cat contacts and <i>T. gondii</i> infection in humans. To address this, we enrolled subjects who contacted with the cat as target group and individuals with no cat contact as control group. Following register of different demographic data (including age, sex, education, foods habit, income status, etc.), whole blood from each enrolled subject of both the target group and control group was collected for serum preparation. <i>T. gondii</i> infected subjects were detected by Toxo Rapid test kit through identifying anti-<i>T. gondii</i> IgM and IgG antibodies in their serum. We found that only three out of twenty subjects who were in contact with cat showed positive IgG response while IgM antibody response was absent for all subjects. When compared with the data from control group, we did not find any significant association (p = 0.33) of cat contact with the transmission <i>of T. gondii</i> into human. However, with this small number of study subjects, we cannot conclusively say that there is no impact of cat contact on the transmission of <i>T. gondii</i> into human. Whether any association exists or not can be ascertained with a large number of subjects from different areas of Bangladesh in a future study in the population.展开更多
