新中国成立初期,马克思主义在新疆地区的传播,历经了从边缘走向中心、从隐蔽走向公开,进而发展为常态化的历史过程。这一过程,蕴涵着马克思主义理论的内在诉求,是中国共产党执政的在场体现,也深度契合了新疆地区各族人民的迫切需求。面对传播过程中出现的话语、文本和媒介等现实问题,党和政府通过加强党组织建设以建构话语路径、翻译出版经典著作以建构文本路径、完善本土大众传媒以建构媒介路径等来化解问题,从而为新疆维吾尔自治区成立奠定了思想与理论基础,强化了中国共产党在新疆地区的组织建设,也推进了本土传播媒介的发展与提升,更为马克思主义在民族地区传播的理论探究提供了现实参考。 相似文献

当今世界多民族国家大多面临如何实现国家社会凝聚,民族认同与国家认同如何一致起来的问题。利用“田野回望”这一认识和研究方法,从生活实际出发,在无论是作为俄罗斯地理的边缘,还是人文的边缘——图瓦,回望莫斯科,回望俄罗斯,回望中央、核心,在图瓦感受俄罗斯民族国家认同,把脉俄罗斯社会凝聚状况。研究显示,图瓦族传统文化功能依然发挥核心作用,同时大量吸收了俄罗斯文化及现代文化要素;“图瓦族”-“我们是图瓦人”的民族意识、民族情感、民族认同意识尚很浓厚,同时俄罗斯国家认同明确,并迫切希望本族、本地区获得高速发展。图瓦个案表明,二十一世纪俄罗斯民族关系的主流表现为民族共生,文化吸收,民族认同与国家认同日益一致的发展趋势。 相似文献

ABSTRACTGames can be a powerful tool for learning about statistical methodology. Effective game design involves a fine balance between caricature and realism, to simultaneously illustrate salient concepts in a controlled setting and serve as a testament to real-world applicability. Striking that balance is particularly challenging in response surface and design domains, where real-world scenarios often play out over long time scales, during which theories are revised, model and inferential techniques are improved, and knowledge is updated. Here, I present a game, borrowing liberally from one first played over 40 years ago, which attempts to achieve that balance while reinforcing a cascade of topics in modern nonparametric response surfaces, sequential design, and optimization. The game embeds a blackbox simulation within a shiny app whose interface is designed to simulate a realistic information–availability setting, while offering a stimulating, competitive environment wherein students can try out new methodology, and ultimately appreciate its power and limitations. Interface, rules, timing with course material, and evaluation are described, along with a “case study” involving a cohort of students at Virginia Tech. Supplementary materials for this article are available online. 相似文献

This study aims to examine housing typologies for older adults in the light of three qualitatively examined exogenous factors: policy, societal developments, and technology. The developments in inpatient and assisted ambulatory housing facilities for older adults have been mapped from 1945 to 2016 using quantitative data. Using these data, five transition periods can be distinguished. Within the first transition periods, policy factors were tremendously important, while within the later ones, societal influence empowered by technological change became the primarily driving factor. This research shows that the classification of inpatient, assisted ambulatory housing, and outpatient housing may no longer be applicable in its current form. 相似文献

In this paper, we present an algorithm for clustering based on univariate kernel density estimation, named ClusterKDE. It consists of an iterative procedure that in each step a new cluster is obtained by minimizing a smooth kernel function. Although in our applications we have used the univariate Gaussian kernel, any smooth kernel function can be used. The proposed algorithm has the advantage of not requiring a priori the number of cluster. Furthermore, the ClusterKDE algorithm is very simple, easy to implement, well-defined and stops in a finite number of steps, namely, it always converges independently of the initial point. We also illustrate our findings by numerical experiments which are obtained when our algorithm is implemented in the software Matlab and applied to practical applications. The results indicate that the ClusterKDE algorithm is competitive and fast when compared with the well-known Clusterdata and K-means algorithms, used by Matlab to clustering data. 相似文献

This article measures long term trends in policy coherence for development. Based on result chains, it develops a counterfactual methodology, and then applies it to assess changes in inputs, outputs and outcomes over time. While the literature does not indicate any significant change in policy coherence for development over the last decade, this research finds that, if the time scale is lengthened to 50 years, an overall increase in policy coherence for development of the Dutch government, vis‐à‐vis the DR Congo, in the domains of finance and security, can be detected. These changes in policy coherence for development inputs seem to have contributed, in conjunction with similar policies from other countries, in some instances, to positive outcomes in the DRC. 相似文献

AbstractThis article provides findings of a qualitative study exploring the interactions of eight Deaf participants and one hearing ally with the justice system in Northern Ireland, where the Disability Discrimination Act requires solicitors to make ‘reasonable adjustments’ in order to provide effective access to Deaf clients. Three thematic categories emerged: (a) barriers to accessing justice, (b) work Deaf people do for access, and (c) the need to educate solicitors about access. A central strain ran through these themes: the idea that ‘reasonable adjustment’ must reflect the value of sign language interpreters in facilitating effective communication access for all the parties. 相似文献
