传播先进文化是新闻传媒的根本任务

江泽民总书记提出的兰个代表”重要思想为新闻理论的创新赋予了鲜明的时代特征,新闻传媒传播先进文化既是对历史的继承,又是新闻事业渐进发展的结果。传播先进文化的核心内容是传播马克思列宁主义、毛泽东思想和邓小平理论。新闻传媒业木身的繁荣创新是传播先进文化的必要保证,其关键是发展,是创新。

建立生态补偿机制的法律思考

生态补偿机制,就是以改善或恢复生态系统服务功能为目的,以经济手段为主,调整相关利益者(保护者、破坏者和受益者)利益分配关系的一种制度安排,生态补偿机制的实施有利于解决地区发展不平衡和社会不公平问题,法律是生态补偿机制有效实施的重要手段。从生态补偿机制的核心入手,分析了其实施法理基础和基本原则。

From value to values: sustainable consumption at farmers markets

Advocates of environmental sustainability and social justice increasingly pursue their goals through the promotion of so-called “green” products such as locally grown organic produce. While many scholars support this strategy, others criticize it harshly, arguing that environmental degradation and social injustice are inherent results of capitalism and that positive social change must be achieved through collective action. This study draws upon 18 months of ethnographic fieldwork at two farmers markets located in demographically different parts of the San Francisco Bay Area to examine how market managers, vendors, and regular customers negotiate tensions between their economic strategies and environmental sustainability and social justice goals. Managers, vendors, and customers emphasize the ethical rather than financial motivations of their markets through comparisons to capitalist, industrial agriculture and through attention to perceived economic sacrifices made by market vendors. They also portray economic strategies as a pragmatic choice, pointing to failed efforts to achieve justice and sustainability through policy change as well as difficulties funding and sustaining non-profit organizations. While market managers, vendors, and customers deny any difficulties pursuing justice and sustainability through local economics, the need for vendors to sustain their livelihoods does sometimes interfere with their social justice goals. This has consequences for the function of each market.

不同支持物对地灵(Stachys floridana Schuttl.ex Benth)试管苗生根的影响

以脱脂棉、琼脂、蛭石、河沙、壤土为支持物,在1/2MS+NAA1.0mg/L+6-BA0.5mg/L培养基上对地灵试管苗生根情况进行了分析。结果表明,支持物对地灵的生根有明显影响,在珍珠岩、琼脂和脱脂棉中地灵的生根率均达到100%,各处理之间差异不显著;生根质量以珍珠岩中最优,幼根能产生大量多级分枝,形成较为强大的根系,且不同支持物试管苗的移栽结果也表明,珍珠岩在地灵试管苗生根中是琼脂的理想替代物。     

论电子媒介背景下儿童文学的阅读价值

2006年9月在中国澳门召开的国际儿童读物联盟(IBBY)第30届大会,其中的议题之一就是“儿童读物与多媒体时代”。电视、电脑等电子媒介的普及,对人们接受知识和信息的方式以及生活方式产生了深刻影响,特别是对儿童的学习方式、游戏方式以及心灵发育、思维养成都产生着不可低估的影响。本文就电子媒介正在影响儿童身心发育的现实状况进行分析,提出重新认识儿童文学之于儿童精神建构的重要性,呼吁重视儿童文学阅读对于儿童心灵成长的精神价值,有针对性地倡导家庭和学校重视儿童文学阅读。

Effects of permanent magnetic fields on the proliferation of Phalaenopsis protocorm-like bodies using liquid medium

Magnetic fields (MFs) have been applied for the first time in orchid micropropagation. Protocorm-like bodies (PLBs) – approximately 3 mm in diameter – first derived from leaf segment culture of Phalaenopsis Gallant Beau ‘George Vazquez’, were subcultured every 2 months, and served as initial explants. The proliferation of Phalaenopsis PLBs in liquid medium in the Miracle Pack^® culture system was affected by the action of different intensities and polarities of MFs: 0.1, 0.15 and 0.2 Tesla (T) at North (N) and South (S) poles. The MF of 0.1 T – S resulted in the greatest fresh weight of regenerated PLBs. The average number of neo-PLBs formed per clusters in the PLB treated by MF: 0.1–0.2 T was decreased compared to the control exposed to natural MF (5 × 10⁻⁶ T). The proliferation of PLBs under 0.15 T – MF at both N and S poles for 2 and 7 weeks demonstrated that a longer duration of exposure to an MF of 0.15 T, regardless of the polarity, resulted in greater biomass of newly formed PLBs and smaller average number of newly formed PLBs. The S pole of MF had stronger effects on Phalaenopsis PLBs proliferation than the N pole did in all treatments.     

Dynamics of public attitudes toward bears and the role of bear hunting in Croatia

Successful carnivore conservation depends on public attitudes and acceptance levels of carnivores, and these are likely to change as circumstances change. Attitude studies repeated in time that can demonstrate such change are rare. Our study surveyed Croatian rural inhabitants in 2002 and in 2008 and analyzed their responses to detect a change in attitudes toward brown bears (Ursus arctos) over time. Important developments occurring in Croatia at the time of our research included a more centralized and more clearly defined bear management strategy, and an increase in the bear population. We constructed models to explain respondent’s value orientations, their level of perceived threat and their acceptance capacity for bears. Findings show that while value orientations and the overall level of perceived threat did not change over time, bear acceptance capacity was reduced. This suggests that the increase in the bear population and perhaps the more centralized bear management reduced respondents’ willingness to accept a larger bear population. We conclude that continuous public involvement in bear management is essential in order to maintain a feeling of control over the bear among the local population. Furthermore we argue that hunting is an important form of public involvement in the region, serving to reinforce existence and bequest values of the bear and increase its public acceptance.
