Media framing of aquaculture     

《Marine Policy》2017

Norway is the world's largest producer of farmed salmon. Aquaculture is the country's second largest export industry and thus vital for employment in coastal areas of Norway. The industry is dependent on public acceptance and good standing in local communities in order to gain access to new sites and to be able to sell its product. Public opinion (and assumptions about public opinion) on aquaculture may influence the industry's framework conditions and policy. Being located in coastal and rural areas, the industry must rely on the media to spread information to the public about the industry. Therefore, the media are an important source of information about farmed salmon, and the way the media present aquaculture issues has an impact on public opinion as well as authorities. This article examines how the aquaculture industry is portrayed in Norwegian newspapers and discusses how media topics and media framing may influence public opinion. The analysis shows that the most frequent topics covered in Norwegian newspapers are connected to the environment, aquaculture industry, and politics, where the concerns about the environment are dominant within the risk frame. The negative images portrayed by the media have a strong agenda-setting force and may skew public opinion to a narrow focus on environmental risks, influencing both the debate's content and the regulators’ increased emphasis on environmental risks. This is strengthened further by the focus on sustainability, where the focus is solely on the dimension of environment, making other sustainability dimensions less prominent in the media coverage.  相似文献

黔西北水东—五指山地区铅锌矿位于扬子陆块西南缘,紫云—垭都北西向构造旁侧,是黔西北铅锌成矿带的一个组成部份,通过该地区矿产资源远景调查及矿产评价成果展现了较好的找矿前景,发现了中型矿床5个,并在攻深找盲取得了突破性进展。笔者通过区域控矿因素、成矿地质背景分析,结合工作成果及认识,模拟类比在相似地质条件,指出找矿方向,认为区内成矿地质条件优越,找矿前景好,具备寻找大型、超大型矿床的潜力。  相似文献   

“小产权房”产生的原因及对社会经济的影响     

王静 《山东地质》2010,(4):46-49

在高房价催生下,＂小产权房＂在全国呈蔓延趋势。该文通过对淄博市淄川区（县级）＂小产权房＂情况的调查,厘清了＂小产权房＂的概念和内涵,摸清了＂小产权房＂的主要分布,从不同角度和层面阐释了＂小产权房＂的客观存在,更从国家政策制度上分析了为何这类房产只能＂小产权＂,而不能＂大产权＂,揭示了＂小产权房＂是我国加快城市化进程中住房建设政策缺位的必然,我国房屋建设管理体制还有待于进一步改革、协调和统一。  相似文献   

孢囊及其与赤潮爆发关系的研究进展   总被引：2，自引：0，他引：2  

丁德文  刘胜浩  刘晨临  林学政  边际  黄晓航 《海洋科学进展》2005,23(1):1-10

某些藻类(特别是甲藻),在不适宜生长的恶劣环境条件下能形成休眠孢囊。孢囊下沉到海底,以渡过不良的生存条件。一旦环境条件适宜,孢囊就大量萌发形成浮游细胞和优势群体,从而诱导赤潮的形成。简述了当前国际上对孢囊研究的最新进展,从孢囊和营养细胞相互转化的角度探索了孢囊与赤潮形成的关系,以及分子生物学技术在赤潮生物及其孢囊的定性、定量及赤潮发生监测中的应用。  相似文献

Zonation of metropolitan France for the application of earthquake-resistant building regulations to critical facilities Part 2: Seismic zonation     

M. Bour  P. Dominique  J.L. Blès  P. Godefroy†  C. Martin  M. Terrier 《Journal of Seismology》2000,4(3):231-245

The seismotectonic zonation of Metropolitan France(part 1) and the derived seismic zonation (part 2)were carried out in order to facilitate andstandardise the application of earthquake-resistantbuilding regulations to critical facilities forreasons of environmental protection (Decree No.91-461, Ministerial Order dated 10 May 1993).According to current French legislation, adeterministic approach was adopted for the executionof these two successive zonations.The seismic zonation is based on a 2.5 km square gridcovering the whole of Metropolitan France, in whicheach cell is defined by the maximal macroseismicintensities that could be induced by a `MaximumHistorically Credible Earthquake' (MHCE) and aSeismic Safety Evaluation Earthquake (SSEE) innearby seismotectonic units. The values of theseintensities were calculated by displacing thereference earthquakes of the seismotectonic zonationto the most penalising position relative to the celland using attenuation laws deduced from the isoseismalcurves specific to each earthquake taken as reference.The zonations obtained for the MHCE and SSEEintensities should thus be considered as the physicalzonations of France for the application ofearthquake-resistant building regulations to criticalfacilities. They are applicable to all criticalfacilities and provide a consistent approach forassessing the levels of seismic aggression to be used(in MSK intensity) at any site in Metropolitan France,as well as the elementary parameters for calculatingthe response spectra usable in the design orverification of structures.  相似文献

The line-of-sight velocities of OB associations and molecular clouds in a wide solar neighborhood: The streaming motions of stars and gas in the Perseus arm     

T. G. Sitnik 《Astronomy Letters》2003,29(5):311-320

We compare the line-of-sight velocities of stars in OB associations within 3 kpc of the Sun and the molecular clouds closest to them. The Perseus arm is used as an example to show that the line-of-sight velocity ranges in which OB-association stars, molecular clouds, and H II regions ionized by these association stars are observed overlap. The streaming motions produced by density waves in the (l, V_LSR) plane were found to lead to an inversion of the distances to objects of the Perseus arm and the interarm space beyond this arm.  相似文献
