In spite of the existence of an extensive debate on cultural policies on the one hand, and on local diversity policies on the other hand, there are still few studies dealing directly with this nexus. This emerging research trend will be discussed in the context of Barcelona and through the analysis of a specific cultural policy field: the planning of permanent festivities.After overviewing its migration history and after presenting the theoretical framework and methodology, this article frames Barcelona’s general cultural policy and intercultural policy patterns, arguing that the Catalan capital is really at a very initial stage of connecting diversity with cultural policy. After that, I will defend the argument that, in spite of recognising diversity, the analysis of Barcelona’s permanent festivities shows that there are also some limits to the development of this connection, due primarily to a lack of democratization of culture. Interviews and a discussion group confirm this empirical diagnosis. The argument I want to put forward is that this lack of participation of immigrants in cultural planning and diversity promotion is probably due to the fact that the two departments in the city represent, indeed, two approaches toward the question of how to promote the nexus between culture and diversity, and thus they are still working separately. The department of culture still has an elitist focus, centred on a culture of excellence, while the immigration department has a more social focus on cultural diversity.  相似文献

空间转型和经济转型——二战后芝加哥中心区再开发   总被引:6,自引:0,他引:6  
芝加哥在战后成功地实现了从传统制造业为中心向现代服务业为中心的经济转型,被认为是美国多元化城市经济的典范。本文从公共政策和城市规划的角度,对芝加哥中心区在战后50年的空间和土地利用变化进行回顾和分析,反映了中心区的复兴过程和城市的经济转型过程,并介绍了2020年芝加哥中心区规划。笔者认为,在芝加哥战后经济转型的过程中体现了城市政府对不同经济发展战略的选择,经济发展的长期目标是创造就业和提高全体居民的生活质量;在经济转型的过程中,城市规划应在土地利用、空间资源分配、社会公平和公正方面发挥作用,为多元化的经济结构创造多样化、高质量的城市空间,而不仅仅关注于物质建设领域。  相似文献

We consider a measure of the diversity of a population based on the λ-measure of hypoentropy introduced by Ferreri (1980). Our purpose is to study its asymptotic distribution for testing hypotheses. A numerical example based on real data is given. This work was partially supported by the Dirección General de Investigación Cientifica y Técnica (DGICYT) under the contract PS89-0019.  相似文献

宁夏是回族高密度聚居地区之一,在受到多元文明的影响下,产生了多样化的回族建筑。当下这些回族建筑遗产在高度工业化与经济化的社会背景中有的即将凋亡,有的情况不佳,有的态势良好。回族建筑遗产的何去何从成为焦点,该文通过实例归纳分类了回族建筑遗产的保护情况,通过田野调查法分析了其所具有的重要影响与文化艺术价值,并展示了其具有多样性种类的特点,为其尽快走上可持续发展路线和进一步的深入研究提供了实例辨析和理论依据。  相似文献

One hundred and twenty-one Salmonella isolates were obtained from food, feed, and live chicken samples derived from 13 countries or regions. In this study, their subtypes were evaluated by serotyping and multilocus sequence typing (MLST), and their genetic profiles were also characterized. It was demonstrated by serotyping on these isolates that 36 various serovars were obtained in this study, of which three serotypes S. Babelsberg, S. Fresno, and S. II were first found in mainland China. Based on Simpson’s index of diversity, the serotyping method had a 0.943 discriminatory power. Meanwhile, there were a total of 42 unique sequence types (STs) characterized by MLST, and the discriminatory power of MLST (D = 0.947) was close to that of the serotyping method. In MLST, hisD revealed the highest levels of nucleotide diversity. In addition, ST-92 was the most common ST represented by 16 Salmonella isolates, followed by ST-367 which was represented by 14 isolates. Seven new alleles were identified, which were associated with other alleles and resulted in the assignment of nine new STs. It was concluded from the results that MLST was generally associated with serotype, but not associated with the epidemiological source of the samples, and antimicrobial resistance patterns.  相似文献

In this paper, parallel distributed detection in wireless sensor network (WSN) is investigated. Sensors are assumed to be transmitting their local decisions to a fusion center through a wireless fading channel using cooperative transmission. To enable cooperative transmission, sensors are divided into groups where sensors in each group help each other in transmitting their decisions in a way that the fusion center receives each local decision as an orthogonal frequency division multiplexed (OFDM) block. The fusion center detects all OFDM blocks sent by all groups to process them in order to obtain a final (global) decision. Using this cooperative transmission scheme enables the fusion center to apply diversity combining methods in order to reduce the fading effects of the channel. Optimal and sub-optimal fusion rules are derived for such system. Simulation results are provided to show the performance improvement that can be obtained compared to the conventional system where each local decision is transmitted to the fusion center individually and no diversity technique is applied at the fusion center.  相似文献
