Discussion of George W. Bush's rhetoric typically focuses on his spoken address, yet his use of cowboy visuals also qualifies as public communication. By visually identifying himself as a cowboy Bush associated his presidency with the story of the mythic cowboy, a powerful concept in American culture. While visual images are typically not considered a substantive and rational form of political communication, Bush's cowboy persona, emphasized visually, prompted widespread debate about his leadership style and approach to national problems, particularly terrorism. While many did not agree with his policies, the simplicity of the visual message and the foundational nature of the cowboy story provided a narrative that prompted a national debate on substantive issues of the day. Language is still considered the critical element of political debate, but as Bush's experience demonstrates, rhetoric includes visual communication as well. 相似文献

Undersøgelsen af areal‐ og ressourceudnyttelsen omkring udvalgte mindre, marginalt beliggende nordbogårde i Vesterbygdens centrale del fokuserer især på gårdsanlæggenes vegetationsressourcer med henblik på beregning af deres bæreevne og foderværdi. På grundlag af biomasseberegninger synes en kronologisk og/eller social betinget bebyggelsesekspansion fra “gode” områder mod mere marginale områder at kunne påvises. Analyser af forholdet mellem græs‐ og husarealer tyder på, at gårde med begrænset græsareal i nærheden kompenserer herfor enten ved at holde flere får eller geder (fremfor køer), som kræver mindre græs som foder og som oftere huses i fritliggende udhuse, eller ved at have større udhuskapacitet til oplagring af hø høstet længere borte fra gårdene. En veldokumenter et gård bliver brugt som eksempel til beregning af vegeta‐tionspotentialets bæreevne, det faktiske dyreholds størrelse og husstandens størrelse. Desuden bliver udnyttelsen af højlandet søgt belyst i forbindelse med betragtninger over forekomsten af anlæg og ressourcer relateret til sæterdrift og rensdyrjagt. 相似文献

This paper supports the need for new policy developments to produce farm conservation plans specific to local areas. It explores attitudes to land management for conservation and economic goals, and presents views of fanners and local conservationists, who are directly involved in agri‐environmental and farm woodland schemes, in three regions of the Highlands of Scotland. It reviews the current state of Scottish agri‐environmental schemes, and presents results of on‐farm workshops conducted with farmers and conservationists and discusses common management plan approaches for environmental action. It concludes that farmers and conservationists are already considering the advantages of local area planning at a local area level and agree that there should be focus on addressing local site specific issues which take into account both the whole farm and its wider environment. 相似文献

White-ground lekythoi ceramics offer important evidence for funeral practices in Ancient Greece (5th century BC). The images painted-on these oil containers provide the best visual narrative for the events surrounding death, including indications that the vessels themselves were used as part of the funerary rites. However, until now, their specific function and treatment within the funeral ceremony was not well understood. We present here material evidence that the vessels were ritually burned, together with the body of the deceased, during cremation, as evidenced by a diffuse purplish-red discolouration found on many white-ground lekythoi. Through EPMA and μXAS studies, we show that: (1) this characteristic purplish-red discolouration is due to the presence of metallic copper nano-particles embedded in a glassy layer; (2) this metal-glass matrix formed as the result of a high temperature reaction between painted-on Cu-based pigments (e.g., Egyptian blue) and the white-ground ceramic slip; and (3) the reaction occurred under a reducing environment. Given the mortuary context for these vessels, we propose the reduction firing to which the vessels were exposed was that associated with the cremation of the body. The observation of discontinuous formation of the purplish-red discolouration along adjoining fragments supports the hypothesis that the vessels were broken prior to being burned. The majority of lekythoi in museum collections lack information on their original archaeological context, and our data suggest the presence of this purplish-red discolouration may serve as a visual marker for cremation. As such, it is expected our findings will provide a new basis for interpreting how this important class of ceramic, and associated iconographic imagery, relates to Athenian funerary practices and the ancient Greek notion of death. 相似文献
