Achieving sustainable lifestyles or encouraging a counter-reflexivity: exploring motivations for sustainability in a mediated risk society

Ulrich Beck's World Risk Society is becoming an increasingly relevant analysis of contemporary human/environment interaction. However, with this said, Beck's observations remain broad and significantly lacking empirical evidence. This paper explores the relationship between sustainable lifestyles and assertions of one of Beck's central ideas, the emergence of a reflexive modernity at the local scale. By empirically examining the motivation of participants for joining a scheme designed to enhance sustainable lifestyles, this paper will progressively outline the way that individuals in a risk society negotiate global images in a local context and what this means for a reflexive modernity. By exposing the complex interaction of global risk imagery and the effect this has on achieving local sustainability, a more realistic understanding of Beck's theoretical assertions can be applied to an increasingly important policy arena.     

Water purification with sintered porous materials fabricated at 400℃ from sea bottom sediments

A sintering technology for preparing porous materials from sea bottom sediments was developed for use in water purification. The purpose of the present study was to develop methods for converting the sea bottom sediments dredged from Ago Bay into value-added recycled products. The sintered products fabricated at 400℃ were found to be very effective adsorbents for the removal of heavy metals.     

粉煤灰多孔陶粒在水处理中的应用研究

研究采用电厂的粉煤灰为主要原料制备多孔陶粒,分别将其用作水处理中的微生物载体和吸附剂。挂膜结果表明:COD、氨氮这两项指标的出水基本稳定,去除率高。用多孔陶粒作吸附剂处理含铬废水时,等温吸附实验表明,多孔陶粒吸附水中的铬的等温方程基本符合Langmiur等温方程式,在pH值为酸性时对铬的去除率较高。用HCl和NaOH溶液再生多孔陶粒,酸的效果更好。     

The Voice of Science on Climate Change in the Mainstream Turkish Press

This study aims to explore how the Turkish press represents the discourse of climate change scientists. This is achieved by analyzing climate change-related articles that quote scientists, directly and indirectly, in two Turkish mainstream newspapers (N = 132, 7 years). The Turkish case illustrates how scientific rhetoric is used for presenting climate change as a matter of concern in an industrializing country. The analysis suggests that climate science is portrayed as an un-discussed authority. News articles rely on data about the disturbance of species and the state of the natural environment to provide proof of global warming, by which they produce an implicit moral imperative. The articles also portray the worst threats and challenges—those pertaining to human society—as residing mostly in the future. We conclude by discussing the implications of the use of a projected future to convey a discourse emphasizing the alarming risks associated with climate change.     

How Aware Are Other Nations of Climate Change? Analyzing Germans’ Second-Order Climate Change Beliefs About Chinese,US American and German People

ABSTRACT

What people believe about the beliefs of other people – second-order beliefs – has been acknowledged as a key factor that shapes public support for international climate policy. However, very little is known about their origins. Based on data from an online survey (n?=?935), we analyzed how German citizens assess the climate change awareness in their own nation as compared to those of the US and China. Even if the public climate change awareness in the US and China factually differs, we found that German citizens equivalently rate both nations similar and much lower than their own, a finding which can be explained with social identity processes and “in-group”/“out-group” biases. Hierarchical regression analyses demonstrate that the attention individuals pay towards television and social media predict second-order beliefs on climate change awareness positively, while attention to print media is a negative predictor.     

Phony Facts and Eco-media: Fake Nature and the Call for Widespread Media Literacy

ABSTRACT

Mermaids: The Body Found privileges mythologized creatures in a fictional narrative disguised as a documentary film in order to blur the boundaries between fact and fiction. This franchise’s decisions to value factors of entertainment over educational material are not uncommon in our consumer-driven society, but the film's engagement with fake fact media potentially repositions how audiences think about important conservation issues by overshadowing critical oceanic environmental topics with fake facts. Although today’s viewers are adept in interpreting media, the mermaid franchise’s use of screen genres, corporate websites, and social media saturates viewers with fake facts making it difficult to delineate between authentic science and fictional narrative. Not a quantitative reception study of audiences, this critical analysis of multiple genres of eco-media examines the difference between fake nature documentary and other types of animal programming and mockumentaries emphasizing that the issue is not strictly a question of entertainment factors or even of the subversion of fact and fiction, alone, but that the real issue lies in the franchise’s willingness to participate in an ever-growing media moment in which programming based on fake and alternative facts has the potential to impact how the public thinks about key issues in politics and science.     

Communicating Haze Crisis Online: Comparing Traditional Media News and New Media Perspectives in Singapore

ABSTRACT

To understand haze-related online communication in Southeast Asia, this exploratory study took a mixed method approach to conduct web analysis of online communication during haze crisis in Singapore, followed by textual analysis of traditional and new media content during peak days. First, web analytics showed that Singapore’s haze online communication occurred mostly on the Twitter platform with primary negative sentiments. Next, textual analysis results found that majority of traditional media-affiliated news provided informative haze reports and centered on positive measurements taken by government and authorities, similar to Public Information Model for crisis management. In comparison, haze-related new media content had diverse topics reflecting laymen’s viewpoints with critical tones and negative sentiments. News portals and blogs used two-way asymmetrical and symmetrical model for crisis management, respectively. Additionally, Social Cognitive Theory’s media diversity perspectives were applied to understand people’s media choices among traditional and new media during natural crisis with environmental influences.     

聚己内酯与聚羟基丁酸戊酸酯的脱氮性能对比

以可生物降解聚合物聚己内酯(PCL)和聚羟基丁酸戊酸酯(PHBV)作为反硝化缓释碳源和微生物载体,利用清水释碳和批式反硝化试验选出适用于再生水反硝化深度脱氮生物滤池的可生物降解碳源滤料,通过比较与分析碳源滤料的表面形态及物质特性和附着微生物的群落特征揭示其性能优越的原因.结果表明,PHBV反硝化启动时间短,反硝化速率高,剩余有机物浓度低,相比PCL具有更稳定持续的反硝化效果.原因是其表面粗糙,且含有大量C—O和CO等亲水性基团,易于微生物附着和降解利用;其表面附着的微生物种类多样,其中发硫菌属(Thiothrix)、假单胞属(Pseudomonas)、菌胶团属(Zoogloea)、黄杆菌属(Flavobacterium)和脱氯菌属(Dechloromonas)等优势菌属均具有异养反硝化功能.因此,PHBV更适合作为再生水反硝化深度脱氮生物滤池的碳源滤料.     

基于网络的交通安全宣传教育研究

为了建立我国交通安全宣传教育网络平台,通过网络平台进行多形式的交通安全宣传教育。采用网站检索的方法,梳理了国内、外主要城市交通安全宣传教育网站,并从专业性、系统性、针对性、形式多样性等角度进行研究。研究发现国外交通安全网站具有分类细致、系统性强、参与互动性强等特点。因此建议我国应加快明确重点教育人群,建立系统性的、专业的、多形式的交通安全宣教内容,引入社会团体等加入宣传教育的队伍,提高全面积极参与、提高关注度。
