濒危语言申报非物质文化遗产保护的思考——以居都仡佬语为例

以居都仡佬语为例,阐明濒危语言属于非物质文化遗产保护的范围,但不宜作为主体申报非物质文化遗产保护。对于濒危语言这种特殊的非物质文化,我们可以寻求其他更适宜的保护方式。

Bayesian inference for generalized additive mixed models based on Markov random field priors

Most regression problems in practice require flexible semiparametric forms of the predictor for modelling the dependence of responses on covariates. Moreover, it is often necessary to add random effects accounting for overdispersion caused by unobserved heterogeneity or for correlation in longitudinal or spatial data. We present a unified approach for Bayesian inference via Markov chain Monte Carlo simulation in generalized additive and semiparametric mixed models. Different types of covariates, such as the usual covariates with fixed effects, metrical covariates with non-linear effects, unstructured random effects, trend and seasonal components in longitudinal data and spatial covariates, are all treated within the same general framework by assigning appropriate Markov random field priors with different forms and degrees of smoothness. We applied the approach in several case-studies and consulting cases, showing that the methods are also computationally feasible in problems with many covariates and large data sets. In this paper, we choose two typical applications.     

蔑视与改造精英——世纪末小说的一大景观

本文以世纪末小说为立足点,揭示了转型期中国社会文化冲突的一大特征———颠覆精英,及其潜在的现实背景。并指出：文化痞子、城市平民、都市白领对精英的蔑视与挑战固然有其不可替代的革命意义,但如果走向另一个极端,也可能导致灾难性社会危机,因而主张各阶层的文化交流与沟通     

论广东在明末清初传教活动中的地位

明末清初天主教首先在广东的澳门建立了基地,进而深入肇庆、韶州和广州,然后在北京播种于宫廷、传扬于全国。近代广东得风气之先,在基督教传教活动中起了特殊作用,一因广东具有优越的博采异域文化的地理位置和古老传统;其次由于岭南文化长期以来所形成的内引外联的开放性;再次,明末清初天主教传教士在广东的居留与考察,为其了解中国国情、确立文化传教和结交上层、从而获得合法传教身份的方针提供了人文环境。

Two-dimensional generalisations of dynamic programming for image analysis

Dynamic programming (DP) is a fast, elegant method for solving many one-dimensional optimisation problems but, unfortunately, most problems in image analysis, such as restoration and warping, are two-dimensional. We consider three generalisations of DP. The first is iterated dynamic programming (IDP), where DP is used to recursively solve each of a sequence of one-dimensional problems in turn, to find a local optimum. A second algorithm is an empirical, stochastic optimiser, which is implemented by adding progressively less noise to IDP. The final approach replaces DP by a more computationally intensive Forward-Backward Gibbs Sampler, and uses a simulated annealing cooling schedule. Results are compared with existing pixel-by-pixel methods of iterated conditional modes (ICM) and simulated annealing in two applications: to restore a synthetic aperture radar (SAR) image, and to warp a pulsed-field electrophoresis gel into alignment with a reference image. We find that IDP and its stochastic variant outperform the remaining algorithms.
