全球化语境下的世界语言生态危机

全球化助推下的英语强势蔓延,大大加剧了世界范围内语言濒危和灭绝的程度和速度。语言生态隐喻为语言濒危研究提供了主流范式。以联合国教科文组织（UNESCO）为首的国际社会为拯救濒危语言不懈努力,步履维艰。非强势语言民族国家应理性接受语言生态演化,在合理利用强势语言价值和保护民族文化财产两者间需求平衡点。

Ostracod fauna of salt Lake Acıgöl (Acı Tuz) (Turkey)

Lakes and wetlands in Mediterranean regions are overexploited and contaminated without sufficient local governmental control. The biodiversity of Salt Lake Ac?göl (Turkey), an internationally recognized ecosystem, is presently endangered by management plans. This study aims to analyse the ostracod community to establish its ecological status as a base for future paleoecological studies using ostracods to reconstruct the recent evolution of this wetland. Samples were collected seasonally and 13 species were recorded. Multivariate classification and ordination statistical methods revealed a major difference between assemblages related to the relative abundance of species tolerant of desiccation vs. species preferring permanent waters. Cyprideis torosa, mainly found in saline, low diversity sites, is a euryhaline species regarded as an indicator of future lake conditions if inappropriate water resource management continues.     

生态学视域下学校危机管理策略

学校管理运行体系是一个独特的社会生态系统,学校生态系统的发育是按照社会生态系统的发展规律开展的。在某种情况下生态系统失衡为系统非常态,当系统处于非常态下,可能导致生态危机发生。学校危机管理是学校管理的重要内容,具有很现实的社会安全价值。管理主体应采取有效措施预防危机,及时预警危机,积极应对危机,特别是适时、适地置入生态干预因子,以防止危机的出现和系统的灾变,从而维护和保持学校生态系统的平衡、稳定和发展。     

日本古代女性王权的产生及其文化生态

在公元1、2世纪至8世纪日本古代国家的形成过程中,曾经出现过多位女性登上王权宝座。她们的出现对于稳定社会政治,推动国家的体制、制度建设,繁荣文化与物质生活等发挥了不可替代的作用,在日本古代社会发展史中具有重要影响。拟通过日本古代女性王权的出现及其作用分析其历史、社会和政治背景,由此从一个侧面揭示日本女性与日本文化之间的内在联系。     

Satellite Image Adaptive Restoration Using Periodic Plus Smooth Image Decomposition and Complex Wavelet Packet Transforms

A satellite image adaptive restoration method was developed that avoids ringing artifacts at the image boundary and retains oriented features. The method combines periodic plus smooth image decomposition with complex wavelet packet transforms. The framework first decomposes a degraded satellite image into the sum of a "periodic component" and a "smooth component". The Bayesian method is then used to estimate the modulation transfer function degradation parameters and the noise. The periodic component is deconvoluted using complex wavelet packet transforms with the deconvolution result of the periodic component then combined with the smooth component to get the final recovered result. Tests show that this strategy effectively avoids ringing artifacts while preserving local image details (especially directional textures) without amplifying the noise. Quantitative comparisons illustrate that the results are comparable with previous methods. Another benefit is that this approach can process large satellite images with parallel processing, which is important for practical use.     

Species of Oswaldella Stechow, 1919 (Cnidaria: Hydrozoa: Kirchenpaueriidae) from US Antarctic expeditions,with the description of three new species

Seventeen species of the genus Oswaldella Stechow have been studied, three of which are new to science (Oswaldella frigida sp. nov., O. medeae sp. nov. and O. monomammillata sp. nov.). The material studied was collected by several US Antarctic expeditions. Each species is described and figured, the systematic position amongst allied species is discussed and available data concerning autecology and geographical distribution are given. The remaining eight known species of the genus are also considered, regarding synonymy, autecology and geographical distribution. Finally, a general survey of the bathymetrical and biogeographical distribution of the known species of Oswaldella is given.
