中国林业投资状况分析

森林作为地球陆地生态系统的主体，在维持区域乃至全球环境中具有不可替代的独特作用。可持续发展理论20世纪80年代末引入林业后，生态林业的发展越来越受到各个国家生态环保部门的重视。我国林业国家投资战略重点从重森工、轻营林逐步转为以营林投资为主兼顾森工，在很大重度上体现了上述观念。     

专利转化特征精准识别与预测 ——以人工智能芯片为例

探讨前沿科技领域专利转化特征并对其进行精准识别与预测,对于我国破解“卡脖子”技术难题及实现科技自立自强具有重要意义。选取人工智能芯片专利领域,采用机器学习算法测度最优转化预测方案,分析全球范围内主要国家或地区专利成功转化影响因素,从企业/高校、国内/国际等不同层面总结专利成功转化的主要特征。结果发现：随机森林算法预测效果较好,人工智能芯片领域专利转化概率服从对数曲线分布,影响高校/企业、国内/国外专利转化特征的因素有所不同。最后,提出高校/科研机构应注重高价值专利维持和团队合作、企业应提升专利技术质量和撰写质量等政策建议。     

Impact of a moral hazard problem in the Joint Forest Management Programme: a study from forest‐dependent households in West Bengal

This study seeks to explore the impact of a moral hazard problem in the Joint Forest Management (JFM) programme between the government and forest fringe communities of a province in West Bengal, India. It suggests that if there is no incentive plan for the poor, it is hard for the government to monitor their actions. The poor tend to take welfare subsidies and yet harvest optimally. A good incentive fee dependent on their work (output) is required for livelihood sustenance of poor people and sustainability of forest resources.     

论我国森林认证的发展现状、问题与对策

森林认证又称FSC认证或木材认证。开展森林认证,有助于推动林产品贸易与国际接轨、扩大林产品对外贸易;有助于建立三位一体的生态文明。目前我国开展森林认证还存在着诸多问题,为推动我国森林认证的健康发展,我们应该从以下几方面做好工作：加强国际交流与合作,尽早建立与FSC互认的认证体系;强化政府监管,规范森林认证市场;深化集体林权制度改革,加快林业信息化建设;政府应对获得森林认证的出口企业提供政策扶持;努力争取FSC认证,避免市场过分集中;充分发挥行业协会的作用。     

林下经济视域下广西＂林改＂问题研究

广西＂林改＂目标明确、领导重视、措施到位,起步晚、进度快,群众热情高、发展势头好。＂林改＂有利于广西林业经济发挥比较优势、消除发展障碍、改善人民生活、促进可持续发展、激发农民林业生产积极性。＂林改＂为广西林下经济发展创造良好条件,林下经济已成为林业经济发展的新亮点。应当加大宣传力度,出台实施促进林下经济发展的政策、措施,加强林区基础设施建设和森林防火工作,加大龙头企业扶持力度,加快社会服务体系建设,促进广西林下经济的发展。     

Crop burning and forest fires: Long-term effect on adolescent height in India

This paper examines the effect of biomass burning on adolescent health in India. The biomass burning problem is quite acute especially in North India, with some states experiencing forest fires and few states actively engaging in crop burning practice. We combine remote sensing data on biomass burning events with a pan-India survey on teenage girls (TAG survey). We exploit regional and temporal variation in our data to establish the link between occurrence of extremely high levels of biomass burning during early life and adolescent height for girls in India. Our results indicate that exposure to extremely high level of biomass burning during prenatal and postnatal period is associated with lower height (by 0.7 percent or 1.07 cm) later in life. Girls from North India are found to be especially vulnerable to the harmful effects of exposure to biomass burning.     

Narratives of the future: Suspending disbelief in forest-sector scenarios

Scenario analysis considers highly uncertain future conditions. The method involves developing and analyzing plausible narratives of the future and evaluating them for a range of implications. The power of scenarios lies in creating and considering compelling stories about the future. Thus, narrative, defined as an account of a series of events, is central to the process and plays a pivotal role in engaging participants in a scenario analysis exercise. While a good scenario story can engage individuals and influence their suspension of disbelief, we know little about how participants actually respond to the scenarios so they can, and will, suspend disbelief in scenario outcomes.We explored the role of narrative in suspension of disbelief in a scenario-based study of the long-term future of Canada's forests and forest sector. We discovered that specific aspects of the scenario narratives themselves influenced participants’ suspension of disbelief. While interacting with the scenario narratives, participants actively worked to suspend disbelief by creating new narratives or accessing other existing ones, and by projecting themselves into the scenarios as characters in the stories. Our results may help scenario writers, practitioners, and researchers understand what, in one project, cued people's abilities to suspend disbelief and engage productively in discussions about possible futures.     

云南石林景点导游作为景观的旅游建构

文章在人类学田野调查基础上,以云南石林景点导游作为旅游景观的建构为切入点,梳理20世纪80年代以来政府对民族身份、性别在导游准入、导游管理中的认识和变化,以及导游自身的文化展演和符号行为等,以此呈现人、人的景观被规范到自然景现中,从而成为共同旅游景观的这一实践过程,并透过这一过程反映当地人的旅游实践.同时,在中国的文化背景和脉络下,对大众旅游表现出的不同意涵,该个案希望能提供一些有意义的启示.
