我国野生动物所有权立法述评

野生动物所有权在野生动物保护事业中具有十分重要的地位,为此,我国先后制定了多部与野生动物所有权有关的法律法规,将野生动物所有权纳入法律调整的范围。但是受制定法律法规时各种条件的限制,目前我国野生动物所有权立法存在着一些不尽合理的地方,本文通过对我国野生动物所有权规范性法律文件的梳理,分析了立法方面存在的不足,并提出了立法建议。

A multi-scale assessment of human and environmental constraints on forest land cover change on the Oregon (USA) coast range

Human modification of forest habitats is a major component of global environmental change. Even areas that remain predominantly forested may be changed considerably by human alteration of historical disturbance regimes. To better understand human influences on the abundance and pattern of forest habitats, we studied forest land cover change from 1936 to 1996 in a 25000 km² landscape in the Oregon (USA) Coast Range. We integrated historical forest survey data and maps from 1936 with satellite imagery and GIS data from 1996 to quantify changes in major forest cover types. Change in the total area of closed-canopy forests was relatively minor, decreasing from 68% of the landscape in 1936 to 65% in 1996. In contrast, large-conifer forests decreased from 42% in 1936 to 17% in 1996, whereas small-conifer forests increased from 21% of the landscape in 1936 to 39% in 1996. Linear regression models were used to predict changes in the proportion of large conifer forest as a function of socioeconomic and environmental variables at scales of subbasins (mean size = 1964 km², n=13), watersheds (mean size = 302 km², n=83), and subwatersheds (mean size = 18 km², n=1325). The proportion of land in private ownership was the strongest predictor at all three spatial scales (partial R² values 0.57–0.76). The amounts of variation explained by other independent variables were comparatively minor. Results corroborate the hypothesis that differing management regimes on private and public ownerships have led to different pathways of landscape change. Furthermore, these distinctive trajectories are consistent over a broad domain of spatial scales.     

资本主义生产关系是破解马克思“重建个人所有制”之钥匙

通过对生产关系创新理解,准确把握马克思的资本主义生产关系本义,解释了马克思“重建个人所有制”真实意思是恩格斯的重新建立消费资料个人所有,坚持了马恩列思想的严肃性和一致性；我国必须坚持和发展马克思主义基本原理,要学会在不同的时代和历史条件下,应用马克思主义基本原理即马克思主义中国化.     

“姓公”“姓私”之争与农地产权认识困境突围

学界对于农地产权问题的相关争论,多集中于农地公有制还是私有制更能促进公平与效率.本研究梳理了农地产权问题的不同观点,并分析了这些观点分歧的原因.在此基础上,进一步论证了我国农地产权制度的实践困境不在于“姓公”与“姓私”,而在于农地管理主体（政府）、开发主体（商人）以及经营主体（农民）各自权益边界不清,导致投机盛行,不利于社会公平与效率.为此要突破认识障碍,搁置农地公属私属之争,凝聚“确权”共识.即,以明确使用权而未必是所有权来充实土地权益内容;通过明确的权益边界,排除农地相关主体在使用和处置农地过程中的投机行为,维护公平与效率.     

Dog and owner characteristics affecting the dog–owner relationship

The nature of the relationship between companion dogs and their owners has important impact on the effect of life for both dog and owner. Identifying factors that affect the dog–owner relationship will assist the understanding of how the successful relationship is achieved and how the less successful relationship is mended, with potential benefits for the welfare of both species. In the present study, we investigated the effect of several dog and owner characteristics, including the personality of the dog, on the dog–owner relationship as measured by the Monash Dog Owner Relationship Scale (MDORS). Data were collected by inviting owners of dogs that had been tested on the Danish Dog Mentality Assessment (DMA) to answer an online questionnaire. We were able to match 421 owner answers with their dogs' DMA test results. The questionnaire consisted of the 28 items of the MDORS, as well as questions about the owners and their dogs. Using factor analysis, 5 dog personality traits could be derived from the dogs' test results on the DMA. The predictive value of questionnaire-based owner and dog variables and the 5 dog personality traits on the dog–owner relationship was tested using multiple linear regressions: 1 for each of the 3 subscales of the MDORS. Overall, the variables investigated only predicted a small proportion of the variance in MDORS scores, and owner characteristics appeared to influence the dog–owner relationship more than dog personality traits did. We found that children in the family and using the dog only for company were negatively associated with the owners' perception of the relationship with their dogs. The only dog characteristics to predict the dog–owner relationship were fearfulness and fear-related behavior problems.
