From superabilità to transabilità: towards an Italian disability studies

This article discusses recent academic and theoretical approaches to disability in Italy, situating them in relation to Anglo-American disability studies as well as within the Italian academic context, and sketches out the contours of an emergent Italian disability studies. The discussion centres on three terms that have emerged recently in Italy: superabilità (implying both ‘ability to overcome’ and ‘exceptional ability’); diversabilità (being ‘differently abled’); and transabilità (the desire for, or identification with, a disabled body by a non-disabled subject). The article considers the role of narrative in each of these categories, as well as the way that each deals with the question of limits. While discourses in each category construct or confirm a strong disabled identity, the article argues that transabilità might also be understood as the transcendence of identity on the basis of ability. This alternative understanding puts pressure on the question of identity itself and challenges the very need for narrative (re)construction.

High‐temperature magmatic fluid exsolved from magma at the Duobuza porphyry copper–gold deposit,Northern Tibet

The Duobuza porphyry copper–gold deposit (proven Cu resources of 2.7 Mt, 0.94% Cu and 13 t gold, 0.21 g t^?1 Au) is located at the northern margin of the Bangong‐Nujiang suture zone separating the Qiangtang and Lhasa Terranes. The major ore‐bearing porphyry consists of granodiorite. The alteration zone extends from silicification and potassic alteration close to the porphyry stock to moderate argillic alteration and propylitization further out. Phyllic alteration is not well developed. Sericite‐quartz veins only occur locally. High‐temperature, high‐salinity fluid inclusions were observed in quartz phenocrysts and various quartz veins. These fluid inclusions are characterized by sylvite dissolution between 180 and 360°C and halite dissolution between 240 and 540°C, followed by homogenization through vapor disappearance between 620 and 960°C. Daughter minerals were identified by SEM as chalcopyrite, halite, sylvite, rutile, K–feldspar, and Fe–Mn‐chloride. They indicate that the fluid is rich in ore‐forming elements and of high oxidation state. The fluid belongs to a complex hydrothermal system containing H₂O – NaCl – KCl ± FeCl₂ ± CaCl₂ ± MnCl₂. With decreasing homogenization temperature, the fluid salinity tends to increase from 34 to 82 wt% NaCl equiv., possibly suggesting a pressure or Cl/H₂O increase in the original magma. No coexisting vapor‐rich fluid inclusions with similar homogenization temperatures were found, so the brines are interpreted to have formed by direct exsolution from magma rather than trough boiling off of a low‐salinity vapor. Estimated minimum pressure of 160 MPa imply approximately 7‐km depth. This indicates that the deposit represents an orthomagmatic end member of the porphyry copper deposit continuum. Two key factors are proposed for the fluid evolution responsible for the large size of the gold‐rich porphyry copper deposit of Duobuza: (i) ore‐forming fluids separated early from the magma, and (ii) the hydrothermal fluid system was of magmatic origin and highly oxidized.     

Is it really bridging the gap? Fiber internet's impact on housing values and homebuyer demographics

Fiber internet expansion represents a path to improved economic vitality for Americans, but it is unclear who benefits from it and by how much. We examine the effects of subsidized fiber internet expansion on home prices and homebuyer demographics using data from Wisconsin and an IV approach to correct for fiber network endogeneity. We find fiber internet increases urban and rural housing values by 1.83% ($3,462) and decreases the likelihood a homebuyer is white by 2.88%, but in urban areas only. Fiber internet therefore does not appear to drive minority homebuyers away but may contribute to the urban-rural racial divide.     

比较文明学的当代形态及研究实践

比较文明研究是全球化时代的一种新兴的研究方向与学科,它对于理解当代世界多元文化共存的局面有重要意义,所以受到国际学术界的高度重视;文明与文化概念之间存在着差异与同一关系;比较文明学具有学科建设的方法论意义,比较文明研究的语境受到世界各民族文明之间关系不同历史阶段的影响;国内文明比较研究已经具备创建新学科与理论形态的条件;综合世界比较文明研究的主要模式,中国比较文明研究理论可以将世界文明分为八大文明体系,从文明认识论、本体论、方法论与实践论等层次进行理论建构。     

旅游形象感知模型及其应用研究——以长三角居民对韩国旅游形象感知为例

本项研究调查了近千名长三角地区潜在游客对韩国旅游形象的感知,运用多元统计技术手段分析探讨了刺激因素、个体因素和形象感知三者之间的关系,研究表明,刺激因素(一手信源和二手信源)与个体因素(旅游动机和社会人口统计特征)差异会影响旅游形象的感知,是旅游形象的前因变量.     

我国自然保护区旅游开发的小规模控制模式研究

本文通过对旅游系统的分析,讨论我国自然保护区旅游资源开发模式的选择,认为小规模控制模式是实现自然保护区旅游资源可持续开发的有效途径。文章还提出了适应这一旅游开发模式的规划、投资、开发框架,对其中的规划者认定、规划流程、投资主体遴选进行了探讨。文章强调这是一种与当前社会和谐发展要求相适应的自然保护区旅游发展战略构想,较好地体现出了公平分配、取用有度的可持续发展原则,是一种值得我们进一步去深入研究的旅游发展模式。     

新时期国内旅游抗周期性及双对数需求弹性分析

2000年以来,我国人均收入超过1000美元,国内旅游进入快速增长期,呈现抗周期性的新特征。本文在形态指标分析的基础上,界定了旅游业抗周期的概念及两种表现形式。相关统计数据实证检验发现,2003年SARS危机后,2004年国内旅游强力反弹,2009年国民经济进入低谷期后国内旅游率先恢复,形成一种受短期波动影响较小的惯性增长。同时,本文依据1994年～2012年时间序列数据建立了双对数模型,分析全国及城市居民国内旅游收入弹性和价格弹性,结果显示,收入需求弹性大于价格需求弹性,收入增长对居民国内旅游的推动作用大于价格的限制,形成了“刚性”的旅游需求,这是新时期国内旅游迅猛增长及抗周期性形成的根本原因。     

人民币升值对中国入境旅游的影响评估——基于扩展旅游引力模型的实证分析

汇率变动通过价格效应对入境旅游需求产生影响。在人民币面临较大升值压力的背景下,探讨人民币升值对中国入境旅游的影响具有重要的现实意义。本文基于标准贸易引力模型和传统旅游引力模型,构建一个扩展的旅游引力模型,采用面板数据计量方法实证分析了人民币升值对中国入境旅游发展的影响,结果表明:人民币升值给中国入境旅游发展带来了强烈的冲击,客源国的经济发展水平及其人口规模以及中国的经济发展水平与中国入境旅游发展呈正相关关系,客源国与中国的距离则是中国入境旅游发展的一个阻碍因素。
