旅游业发展影响因子灰色关联分析

为旅游规划、评价、决策等提供科学依据,运用灰色关联动态分析方法,对影响我国旅游发展的因子进行判识,揭示影响旅游业发展的主导因子。研究结果表明,选取的各因子对旅游业发展影响程度存在明显差别,可划分为三个层次:全国图书、杂志和报纸出版量因子的灰关联度最高,说明该因子的变化对发展我国旅游业有着特殊重要意义;国际铁、公路客车、民用航空飞机拥有量对旅游收入的关联度排名靠后,表明公共交通工具并不如所想的对旅游业发展具有强拉动作用;剩余17个因子对旅游业发展影响程度介于两者之间,尤其是旅行社数、城市园林绿地面积、人均GDP、人均消费性支出和人均储蓄存款余额5个因子的关联度近乎1(均为0.99),说明这5个指标对旅游业发展的影响作用仅次于全国图书、杂志和报纸出版量因子,在推动和促进旅游业快速方面具有不可替代的地位。     

美国学界关于中国共产党城市接管史研究述评

新中国城市接管是城市管理与城市建设的一个特殊阶段,其时间虽然较短,但影响深远。中国共产党对新解放城市的接管是中华人民共和国大厦的奠基石,也是中国共产党建政成功与否的关键。因此,研究中共城市接管是洞察中国共产党政权建构与施政理念的重要切入点。美国学界持续关注中共城市接管史,研究内容涉及城市接管的过程、接管干部(含南下干部)以及城市接管之后的社会改造和城市变迁等。随着研究视角的转换,美国学界的关注点亦有所不同。近些年来美国学界相关的研究议题越来越细化,关注点从宏大的政治叙事转向社会结构和城市生活变迁,而研究方法也呈现多样化的趋势。

Abstract

One of the few maps made by the indigenous population of the Americas and dating from the early eighteenth century to have survived, either in original or copied form, is the subject of this article. The map, on deerskin, was given to the new governor of South Carolina, Francis Nicholson, by an unknown Native American. Entitled A Map Describing the Situation of the Several Nations of Indians between South Carolina and the Massissipi River, it has generally been attributed to the Catawba nation. After situating the map in its historical period and detailing the claims for a Catawba origin, these claims are refuted and evidence supplied for a Cherokee origin.     

The Ethical Question in Postwar Central America and the Mutilated Good in Rodrigo Rey Rosa’s El Cojo Bueno

This article examines how the novel El cojo bueno (1996) by Guatemalan writer Rodrigo Rey Rosa posits an ethics that reconstellates the motifs and assumptions that have informed the revolutionary and transition-to-peace efforts of Central America. Through a careful reading of the text, I demonstrate how the novel pushes against the limits of the neoliberal ‘culture of peace’ and gives expression to an ethics that is attuned to the complex sociopolitical conditions of the postwar period. More specifically, I show how the novel develops a moral vision that registers but also resists the impunity, violence, and social disaffection that have devastated the region. The novel dramatizes what the moral life has come to mean in postwar Central America, namely, that it is a matter of grappling with the antinomies of freedom and unfreedom, of compassion and cold survivalism, and refusing to rest easy with either option. Ultimately, El cojo bueno marks a key moment when a new conception of ethics begins to take shape in postwar Central American literature.     

Displacement Ductility Limits for Pile Foundations in Cohesionless Soils

The displacement ductility limit for seismic design of concrete piles is determined for the range of cohesionless soils expected in practice. The curvature ductility capacity associated with specified performance limit states, namely, the “serviceability” and “damage-control” limits, is determined based on the current provisions for confining steel. An analytical model is applied to assess the displacement ductility factor at the specified curvature ductility level. The investigated parameters include the soil stiffness, pile diameter, longitudinal reinforcement ratio, axial force level, and pile above-ground height. A set of design displacement ductility factors is recommended and verified to ensure the satisfactory seismic performance.     

Industrial clusters,organized crime,and productivity growth in Italian SMEs

We examine whether organized crime affects firms’ performance (defined using Total Factor Productivity growth) both directly and indirectly, by downsizing the positive externalities arising from the geographic concentration of (intra‐ and inter‐industry) market‐related firms. The analysis uses a large sample of Italian small‐ and medium‐sized manufacturing firms over the period 2010–2013. The results highlight the negative direct effects of organized crime on firms’ productivity growth. Any positive effect derived from industrial clustering is thoroughly debilitated by a strong presence of organized crime, and the negative moderation effect of organized crime on productivity growth is greater for smaller than for larger firms.     

Moon,mud, and cell phones: geographies of race and construction of difference through normalization

How does the meaning of space emerge and get negotiated when individuals of diverse backgrounds interact with each other? Studies reporting that African Americans tend not to spend time in outdoor space attribute this finding to limited access to resources, cultural values, degree of assimilation to mainstream practices, discrimination in outdoor space, or a perception that outdoor recreational space is “white space”. Little research has addressed how such meanings relate to other meanings attached to outdoor space, let alone how this happens through interactions between people with different views on outdoor space. This article, based on interviews and participant observation of college students on an alternative break trip from the Northeastern U.S. to New Mexico in 2014, shows how students of various backgrounds experienced nature differently, how differences were articulated and explained, and how they subverted normalization processes that render not “being in tune with nature” as deficiency. Suggesting that geographies of race are fluid and influenced by individuals’ agency, this article calls for encouraging students to examine the ways their subject positions have shaped their experiences and challenge cultural bias in what is deemed universally desirable.

‘A Young Tory’? The Early Parliamentary Career of Charles James Fox 1768–74

This article seeks to redress the neglect, even by his biographers, of Fox's early career, when he made over 250 speeches in the house of commons in six years. The period when young Fox supported government was an inappropriate prelude to his later fame as opponent of Prime Minister Pitt and champion of ‘liberal causes’. He was anything but a ‘man of the people’ in his authoritarian attitude and detestation of popular opinion, and yet there were signs that he would not be an administration man in the mould of his father, Henry Fox.
