新媒体背景下公众参与生态文明建设的路径

党的十八、十九大均指出,生态文明建设功在当代、利在千秋。十九大进一步明确提出要构建“政府主导、社会协同、公众参与、法治保障”的生态文明建设新局面。《环境保护公众参与办法》的出台为公众参与环境保护提供了强有力的制度保障,但公众的参与程度与许多因素有关。在积极发动和鼓励公众参与生态文明建设的过程中,政府可发挥新媒体协商平台的作用,提高新媒体的回应能力,为公众参与生态文明建设提供保障;公众应借助新媒体互动平台的功能,进一步提升生态意识,践行生态行为,自觉维护生态环境;环保组织要发挥新媒体的聚焦作用,推动环保组织的成长壮大。     

绿水青山就是金山银山——习近平生态文明建设思想的哲学依据

建设美丽中国、实现中华民族永续发展、建设具有中国特色社会主义,必须抓好生态文明建设。习近平生态文明建设思想以马克思辩证唯物主义原理和我国传统的儒家、道家文化根基中的生存智慧作为哲学依据,是顺应时代要求的新论断。这个思想有着生态自然观与生态经济观相统一、规律性与目的性相统一、继承性与创新性相统一、科学性与实践性相统一的思想特点。有此思想指导,我国全面建成小康社会、夺取新时代中国特色社会主义的伟大胜利、实现中华民族伟大复兴的中国梦必然指日可待。     

长江经济带生态效率时空格局演化及影响因素研究

文章基于108个城市2004-2014年市级面板数据测度了长江经济带城市生态效率的时空演变格局,综合而言,长江经济带生态效率水平呈现出波动上升态势,长江流域城市生态效率分化特征明显,湖南、湖北和四川等长江上游城市生态效率较高,长江上、中、下游地区城市生态效率依次递减.对生态效率的影响因素研究表明,科技创新显著地提高了长江经济带的生态效率,经济快速增长降低了城市生态效率,意味着转变经济增长方式、加快科技创新是提高城市生态效率的有效途径.研究还发现,产业结构偏离度有利于提高城市生态效率,而产业升级抑制了城市生态效率的增长,意味着产业升级并不是提高城市生态效率的捷径.     

税务信息管理权与保护权的冲突与平衡

实践中税务机关与纳税人在信息采集、保有及使用方面存在激烈冲突。究其原因在于公权力与私权利冲突具有必然性、税务信息的权利（力）边界不明且经济性日益凸显及税务机关信息管理的责任机制不健全。借鉴域外经验,中国税务机关信息管理权与纳税人信息保护权的平衡之道在于限制公权力并进一步保障私权利,坚持税收法定、个人权利保护及狭义比例等原则。具体而言,需明确税务机关信息管理权与纳税人信息保护权的范围,构建税务信息分层管理机制,严格化税务机关信息管理的程序,完善纳税人信息的争端解决机制与违法取用纳税人信息的责任机制并加强对税务机关信息管理权的监督,促进税务信息领域的公权力与私权利从冲突中走向平衡。     

生态学马克思主义对西方环境主义的批判和启示

西方环境主义认为人类在地球上的频繁活动将导致地球整个生态系统的破坏，要想解决环境问题就必须限制人类活动，缩小经济发展规模，避免人口过剩；而生态学马克思主义则指出，生态危机产生的根源是由于资本主义私有制的存在，环境污染和人口过剩是资本主义剥削自然和剥削人类的结果，只有建立生态社会主义社会，绿色环境主义者和马克思主义者的可持续发展理想才能实现。     

Analysis of Regional Scale Risk of Whirling Disease in Populations of Colorado and Rio Grande Cutthroat Trout Using a Bayesian Belief Network Model

Introduction and spread of the parasite Myxobolus cerebralis, the causative agent of whirling disease, has contributed to the collapse of wild trout populations throughout the intermountain west. Of concern is the risk the disease may have on conservation and recovery of native cutthroat trout. We employed a Bayesian belief network to assess probability of whirling disease in Colorado River and Rio Grande cutthroat trout (Oncorhynchus clarkii pleuriticus and Oncorhynchus clarkii virginalis, respectively) within their current ranges in the southwest United States. Available habitat (as defined by gradient and elevation) for intermediate oligochaete worm host, Tubifex tubifex, exerted the greatest influence on the likelihood of infection, yet prevalence of stream barriers also affected the risk outcome. Management areas that had the highest likelihood of infected Colorado River cutthroat trout were in the eastern portion of their range, although the probability of infection was highest for populations in the southern, San Juan subbasin. Rio Grande cutthroat trout had a relatively low likelihood of infection, with populations in the southernmost Pecos management area predicted to be at greatest risk. The Bayesian risk assessment model predicted the likelihood of whirling disease infection from its principal transmission vector, fish movement, and suggested that barriers may be effective in reducing risk of exposure to native trout populations. Data gaps, especially with regard to location of spawning, highlighted the importance in developing monitoring plans that support future risk assessments and adaptive management for subspecies of cutthroat trout.     

When work keeps us apart: a thematic analysis of the experience of business travellers

Whilst business travel is deemed important for organisational success and economic outcomes, little is known about the actual process of business travelling from the perspective of individuals who undertake such travel on a regular basis. Thus the current qualitative study examined how business travellers (three women and eight men) attempt to find a balance between work and family, by focusing on how time together and time apart are experienced. The results can be interpreted and framed within work/family border theory in that business travellers' borders are less defined and less permeable, thus requiring them to border-cross more frequently. This necessitates a process of negotiation with key border-keepers (their spouse/partner). Business travellers also undertake compensatory behaviours to make up their time away from family. In order to find a work/family balance, they go through a process of adapting, negotiating and tailoring their lives around their work commitments to alleviate work–life conflict.

Discovering hidden statistical issues through individual-level models in ecological studies

ABSTRACT

In ecological studies, individual inference is made based on results from ecological models. Interpretation of the results requires caution since ecological analysis on group level may not hold in the individual level within the groups, leading to ecological fallacy. Using an ecological regression example for analyzing voting behaviors, we highlight that the explicit use of individual-level models is crucial in understanding the results of ecological studies. In particular, we clarify three relevant statistical issues for each individual-level models: assessment of the uncertainty of parameter estimates obtained from a wrong model, the use of shrinkage estimation method for simultaneous estimation of many parameters, and the necessity of sensitivity analysis rather than adhering to one seemingly most compelling assumption.
