Diffusion research often characterizes the role of the federal government in innovation adoption as a supportive one, either increasing the likelihood of adoption or its speed. We examine the adoption of medical marijuana laws (MMLs) from 1996 to 2014 to shed light on what motivates states to adopt innovations that are in explicit defiance of federal law. Furthermore, we examine whether federal signals have any influence on the likelihood of adoption. In doing so, we utilize implementation theory to expand our understanding of how the federal government's position impacts state policy innovation adoption. We find mixed evidence for the influence of federal signals on the adoption of MMLs. The results suggest that medical marijuana policies are much more likely to be adopted in states when proponents have the political or institutional capital, rather than a medical or fiscal need. Moreover, this political capital is sufficient independent of the federal government's real or perceived position.  相似文献

Abstract

Engineering has discovered some laws of nature as limits to what can be done, from which have developed the sciences of thermodynamics, information theory and cybernetics. Considered as a science, engineering lies between physics and biology, because its machines have physical structures and properties but biological organizations and functions. The old idea of the living body as an engine retains its power in modern biology; and the reconsideration of various natural non-biological processes in terms of engineering and biological concept reveals inadequacies in modern physical theory.  相似文献

《灰阑记》引起了世界的关注,国内有学论及了它的来源和世界性影响问题,这有意义。但学关于《灰阑记》题材来源的说法是不正确的。《灰阑记》虽在内容上与佛教、基督教、伊斯兰教所记的故事有相似之处,但李行道却不是从这三个宗教故事中取材。一,三个宗教虽在唐代以前就传入中国,但其时除了佛教有关故事已翻译过来以外,其他两个同类故事是不是已经翻译过来,难以确定;二.李行道是中国的隐士,不是宗教信徒,他受中国传统化的影响,《风俗通义》是宋元习见之书,他见到的可能性更大;三,元杂剧创作中普遍存在着吸取历史故事、小说等材料进行创作的倾向.李行道所在的平阳是当时杂剧创作的中心之一,他当然会受到这个倾向的影响。因此,我们认为,他是从中国本土的故事受到启发,创作了《灰阑记》。中国本土故事就是见载于《风俗通义》中的黄霸断两妇人争子的故事。《灰阑记》的故事情节、宗旨.与之极为一致。世界几种化中都存在着《灰阑记》式的故事,这一情形值得深入研究。用比较的方法研究中外化及学的相互影响及异同,是有意义的,但应注重事实,不应轻言袭用而贬低一个民族创造化的努力和对世界化的贡献。  相似文献

In Tibetan medicine, all food and medicinal plants have their origin in the four elements (earth, water, fire, air and space). They are therefore classified according to certain characteristics, associated with a particular element. Classification of based upon these characteristics, which can range from intrinsic properties, such as moisture, to the taste of a given food or plant. To classify by element, the nature ofagiven plant is also analyzed according to its initial "seed": its initial "constitutive elements". It is important to remember the distinction between the two uses of the term element. As a tool for classification, the constitutive elements are the lowest common denominators into which a substance can be divided, basically, its essential element. They show the original preponderance of one element-such as water-over another, and determine the final classification of a whole plant as belonging to one or another element.  相似文献

网络关系嵌入、创新扩散与旅游企业创新绩效   总被引:1,自引:0,他引:1  
作为服务业创新的重要分支,旅游业创新研究还处于起步阶段,旅游企业创新绩效及其影响机制研究还很缺乏。本文以嵌入性理论为切入点,构建了旅游企业网络关系嵌入与创新绩效之间关系的理论模型,并以四川剑门蜀道核心景区(剑门关)周边旅游企业为样本,运用回归模型实证研究了关系嵌入性如何通过创新扩散来影响旅游企业创新绩效。研究结果显示:旅游企业网络的强关系有利于提升企业的创新绩效,企业间互惠程度和关系的持久性与创新绩效正相关,创新扩散在旅游企业关系嵌入和创新绩效关系中起部分中介作用。  相似文献

The Mingjiang River originates on the southern slope of Gonggangling Peak of MingshanMountain, at the meeting place of Songpan and Jiuzaigou counties. It bisects Songpan, with a total length of 735 km, including 341 km within Aba Prefecture. The river has helped cultivate many generations in the province of Sichuan.The source of Mingjiang River features majestic peaks, lush grazing grass, deep forests, grotesque rocks, rare animals and a pleasant climate.In the summer and autumn, this part of the world turns into a shining lady whose hair and tender complexion merge with the blue skies and beckoning world of ancient pine trees and firs decorated by blossoming flowers.When winter comes, the shining lady dons a white robe as snow and ice take over.The area where the Mingjiang originates has the most sensitive ecosystem in Sichuan.

十二生肖作为一种古老的民俗文化事象,有着渊源的历史。关于它的起源,历代学者众说纷纭。《辞海》中十二生肖的解释是这样论述的:“古时的术数家拿十二种动物来配十二地支,子为鼠,丑为牛,寅为虎,卯为兔,辰为龙,巳为蛇,午为马,未为羊,申为猴,酉为鸡,戌为狗,亥为猪。”赵翼《陔馀丛考》谓十二生肖之说起于东汉,汉以前没有言者,到了东汉,  相似文献

中国古代玉器探源   总被引:2,自引:0,他引:2  
古玉探源是解决我国玉器的最初源头的科研课题.我国史前五大玉矿资源产地、三大玉文化板块、五支玉文化亚板块的背景决定了我国玉器源头很可能是多元的,似乎不可能出现于一地而向四面八方传播.从迄今已掌握的发掘出土玉器的质量与水平及其玉文化面貌判断,我国玉器起源地之一,可能在兴隆洼文化、查海文化周边或其以北地区.  相似文献
