王渔洋与明遗民诗人姜埰的交往

从有关资料看,王渔洋与姜埰有过一次交往,并由姜埰给王渔洋的赠诗,引出了清初批评王渔洋“清秀李于麟”的诗学话题;这一话题又与王渔洋后来对姜埰“遗命宣州”的批评有关.王渔洋对姜埰的批评,反映出王渔洋后期对明遗民诗人的日渐疏离.     

Passion for a Leisure Activity,Presence of Meaning,and Search for Meaning: The Mediating Role of Emotion

The purpose of this research was to investigate the role of having a passion for a leisure activity on the presence of meaning and the search for meaning in college students’ lives. A path analysis of the results from 322 Chinese university students showed that positive emotions experienced during leisure activities partially mediated the relationship between harmonious passion and the presence of meaning. Negative emotion fully mediated obsessive passion and the presence of meaning as well as obsessive passion and the search for meaning. Obsessive passion was not associated with positive emotion. Implications for the dualistic model of passion, the presence of meaning, and the search for meaning in college students are discussed.     

Partial unit root and surplus-lag Granger causality testing: A Monte Carlo simulation study

Previous literature has shown that the addition of an untested surplus-lag Granger causality test can provide highly robust to stationary, non stationary, long memory, and structural break processes in the forcing variables. This study extends this approach to the partial unit root framework by simulation. Results show good size and power. Therefore, the surplus-lag approach is also robust to partial unit root processes.     

Semiparametric Estimation Methods for the Accelerated Failure Time Mixture Cure Model

This paper provides an overview of two semiparametric estimation methods recently proposed in the literature for the accelerated failure time mixture cure model. We prove that the two estimation methods are asymptotically equivalent. A simulation is conducted to investigate the rate of convergence of the two methods. We apply these methods to fit the accelerated failure time mixture cure model to the survival times of leukemia patients receiving bone marrow transplantation.     

新媒介背景的儿童类纸质媒体发展取向

数字媒介技术的革新加剧了“图像革命”，造成了人的思考能力的滑坡．这一影响加之于儿童则更加明显。儿童作为特殊且脆弱的社会群体，极易陷入新媒介所搅动的文化漩涡中，传统阅读这一儿童基础性认知技能遭遇到严峻考验。儿童类纸质媒体应充分发挥独有优势，与儿童类数字媒体展开错位竞争。从儿童文化内容的创作生产、儿童文化产品的销售渠道、儿童文化消费的最终实现三个层面完成自身的发展与跨越。     

从渔业社区到海权问题:国外海洋人类学研究述评

海洋人类学对渔业社区的生计方式、社会组织结构等问题有着传统的学科关照.然而,在全球化脉络和现代化进程之下,海洋生态、海洋社会以及人海关系被置于巨大的社会变迁中,并呈现出愈加复杂的趋向.通过系统梳理西方海洋人类学的研究成果,本文认为海洋人类学研究正在发生从“渔业社区”到以产权和管辖权为核心的“海权问题”的话题转向.     

刍议历史教学中史料选择三原则

史料在历史教学与研究中,作用十分巨大,须注重史料的挖掘与利用.在利用和选择史料时,尤应重视史料的典型性、鉴别性和全面性.     

丝绸之路经济带农牧业合作的空间、潜力与中国农业“走出去”策略

通过丝绸之路经济带的建设,强化我国与中亚五国在政治、经济、文化和民族间的联系,开展农业领域的合作,发展地区经济,是一件互利双赢的事业.与中亚国家进行深度的农牧业合作,既可以加快这些国家农牧业的发展,提高人民食物保障能力或提高其农产品出口的水平,又可以为我国的涉农企业走向深度参与一带一路建设、消化产能、布局农产品全球供应链提供良好的机遇.     

Non parametric mixture of strictly monotone regression models

In this article, we propose the non parametric mixture of strictly monotone regression models. For implementation, a two-step procedure is derived. We further establish the asymptotic normality of the resultant estimator and demonstrate its good performance through numerical examples.     

灰色多级排队供应链系统的稳定性测度方法

文章以供应链网络为研究基础,建立了一种灰色多级排队供应链系统,并采用多级排队网络方法研究受到达率和服务时间间隔两个扰动量影响时该系统的稳定性测度方法.验证结果显示:对于受到扰动量影响的灰色多级排队供应链系统,均能快速达到稳定状态,且扰动量能改善供应链系统的整体性能,即使出现异常值,该值变化的波动性也较小;在稳定状态后因具有相对固定量的库存水平,系统不再受其他因素的制约,显示了较强的鲁棒性特征.
