李白卒年新论

李白的卒年,依据李阳冰、范传正所记的李白生年和李华所记的李白享年即可确定为大历元年。从曾巩到王琦,对此提出了异议。但他们所提出的依据没有一条是信实可靠的,包括他们认作铁证的《为宋中丞自荐表》,编在至德二载也是不可靠的。要正确地确定李白的卒年,还是要回到李阳冰、范传正和李华那里去。     

流浪乞讨人员救助管理制度的实践社会学分析——以北京市C救助站为例

基于对北京市C救助站的个案调查,以实践社会学为理论指导,比较分析我国救助管理制度的核心理念从＂收容＂转向＂救助＂的转变,尤其对实施过程中的实践逻辑进行了深入探究。研究认为,救助管理制度在运行中,其实践逻辑发生了偏误。要完善救助管理制度,不仅要充分调动社会救助主体的积极性,加强部门合作,而且要从理念上升为行动,确保制度的执行。     

“联系说”视角下商标俗称抢注案的法律思考

商标权的客体为相关公众所认知的商标与商标所标识的商品或服务之间的联系,以此为基础可以认定商标俗称的抢注构成对商标权的侵犯,同时,商标俗称可以被认定为近似商标的一种形式,从而适用《商标法》第52条的规定。此外,在商标俗称的问题上,不能适用法律对驰名商标的特殊保护。     

The athlete as model minority subject: Jose Bautista and Canadian multiculturalism

The discourse of multiculturalism disguises complicated racial dynamics in nations such as Canada. Although white privilege persists, it tends to be mediated through non-white figures who can engender consent from other minority members. These figures have been called model minorities, a role that is well-tailored to celebrated athletes. Athletes who fill the role of model minority represent the ideal immigrant citizen: English-speaking, middle class/bourgeois, disciplined, and hard-working. As such, they serve a disciplinary function for other immigrants by demonstrating how it is they should act and producing a standard against which they are evaluated. The model minority has become a crucial representational figure for multicultural nations like Canada because the political economy of these states requires cheap labour that can be hyper-exploited through the dehumanization of racialization. Drawing on articles in Toronto's most prominent newspapers, I argue that Toronto Blue Jays baseball star Jose Bautista has recently assumed the status of a model minority. I elaborate the functions of the model minority through a reading of Bautista's representation.

民族互嵌式社区治理共同体的系统审视与建构路径——以云南省洱源县郑家庄为考察中心

社会治理共同体视域下推进我国民族互嵌式社区治理共同体建设,既是促进各民族相互嵌入的基本着力点,也是落实民族工作“重在基层”的重要体现。本文通过对郑家庄典型社区进行调查研究,将民族互嵌式社区的系统建构与社会治理共同体建设相结合、相融通,见微知著,研究和探讨多民族社区治理的普遍规律,在共同体叙事中探寻我国民族互嵌式社区治理共同体建构的内在机理与框架体系。郑家庄通过系统推进“居住互嵌、组织互嵌、经济互嵌、文化互嵌与心理互嵌”,探索建构民族互嵌式社区生活共同体、组织共同体、经济共同体、文化共同体与情感共同体,为多民族社区实现“建设人人有责、人人尽责、人人享有的社会治理共同体”目标提供了实践样本。     

Modelling Variability in the Branching Structure of Strawberry Inflorescences

The branching structure of inflorescences of the cultivated strawberry ( Fragaria × ananassa Duch.) is very variable. This paper demonstrates that some aspects of this variability are well described by a simple stochastic model of branching that has two adjustable parameters. The model is shown to provide a good fit to data from a set of almost 700 inflorescences of the cultivar Elsanta, collected over two successive years. For one parameter the maximum likelihood estimator is a moment estimator which is fully efficient even if the detailed branching structure of the inflorescences is not recorded. This parameter provides a convenient summary of branching vigour. The maximum likelihood estimator of the second parameter must be determined iteratively and can be quite inefficient unless the full branching structure is recorded. The model demonstrates that branching structure is affected by the order in which inflorescences emerge on the plant.     

A modified Kolmogorov-Smirnov test for a rectangular distribution with unknown parameters: Computation of the distribution of the test statistic

A recursive scheme for the calculation of the distribution of the test statistic of a modified Kolmogorov-Smirnov-test for a rectangular distribution with unknown parameters is given.     

The robustness of the quasilikelihood estimator

The quasilikelihood estimator is widely used in data analysis where a likelihood is not available. We illustrate that with a given variance function it is not only conservative, in minimizing a maximum risk, but also robust against a possible misspecification of either the likelihood or cumulants of the model. In examples it is compared with estimators based on maximum likelihood and quadratic estimating functions.
