超越有限的图腾——论李白《大鹏赋》与庄子《逍遥游》的继承关系

《大鹏赋》是李白超越有限的精神图腾,他在大鹏的现象中寄寓了自己的自由理想。这篇赋受庄子《逍遥游》的影响明显。但二者又有很大的不同:一为哲学论文,一为文学作品;大鹏不是庄子的理想人格而为李白的理想人格。     

背负恶名谁之过——浅议导游从导间大使到千夫所指之原由

世界各国旅游界对导游都以最美好的词句去形容,说导游业务是旅游业的"灵魂",称导游员是"国家的代表";而在中国,导游二字却意味着欺诈和贪婪.本文特对此现象进行剖析并提出相应的见解.     

论翻译的动态分割点

作为特拉维夫翻译学派的主要代表人物之一,基迪恩·图里关于规范的见解尤为独树一帜。他提出了翻译模式中的规范概念,分别是原始规范、预先规范和操作规范。同时,译者从翻译之前到翻译活动结束主要受到原语文化规范和目的语文化规范的制约,这两种规则如同线的两端,而译者的使命则是在两端间动态地选择自己需要的规则,这犹如在寻找一段距离中的黄金分割点,即最佳点。     

浅谈《结构力学》的双语教学

随着教育国际化的发展,对一些具备基本条件的高校开展双语教学的试点和推广工作是有很意义的。在《结构力学》双语教学中采用启发式、互动式、讨论式教学方法并采取多元化的考核机制,对学生能力的培养和素质的提高具有较大的帮助作用。     

Subset selection in quantile regression analysis via alternative Bayesian information criteria and heuristic optimization

Subset selection is an extensively studied problem in statistical learning. Especially it becomes popular for regression analysis. This problem has considerable attention for generalized linear models as well as other types of regression methods. Quantile regression is one of the most used types of regression method. In this article, we consider subset selection problem for quantile regression analysis with adopting some recent Bayesian information criteria. We also utilized heuristic optimization during selection process. Simulation and real data application results demonstrate the capability of the mentioned information criteria. According to results, these information criteria can determine the true models effectively in quantile regression models.     

Tabu search for covering arrays using permutation vectors

A covering array  CA(N;t,k,v)$\mathsf{CA}(N;t,k,v)$ is an N×k$N\times k$ array, in which in every N×t$N\times t$ subarray, each of the v^t$v^t$ possible t  -tuples over v$v$ symbols occurs at least once. The parameter t is the strength   of the array. Covering arrays have a wide range of applications for experimental screening designs, particularly for software interaction testing. A compact representation of certain covering arrays employs “permutation vectors” to encode v^t×1$v^t\times 1$ subarrays of the covering array so that a covering perfect hash family whose entries correspond to permutation vectors yields a covering array. We introduce a method for effective search for covering arrays of this type using tabu search. Using this technique, improved covering arrays of strength 3, 4 and 5 have been found, as well as the first arrays of strength 6 and 7 found by computational search.     

Human resource management in the just-in-time environment

Successful just-in-time (JIT) implementation requires a multiskilled group-oriented and self-disciplined workforce with good quantitative skills. Little discussion exists in the JIT literature concerning the development of such a workforce. The human resource management (HRM) literature deals with employee issues but does not identify strategies for achieving a JIT workforce. In order to identify appropriate HRM strategies for a JIT environment, a comprehensive model is presented to show the critical linkage between JIT and HRM. Interactions between legal issues, management and union, and human input are examined. The impact of US labour laws on HRM practices is discussed and contrasted with Japanese practices. The literature review of HRM-related JIT articles suggests that HRM practices in the areas of staffing, training and development, compensation, and employee retention can be used to develop an effective JIT workforce. The article will help production managers to understand the impact of specific HRM strategies that are appropriate for developing a JIT workforce.     

Simultaneous inference for treatment regimes

A viable dynamic treatment regime refers to decisions regarding how different treatments and dose levels are tailored through time to match with the patient’s health status. In the therapy for cancer or diseases that require multiple stages of treatments, the effect of preceding treatment (such as growing back of solid tumors or regime-related toxicity) critically influences the selection of treatment in the following stage. So far, analyses of dynamic regimes mainly focus on marginal mean models under the assumption of sequential randomization in a clinical trial. Inference conclusions regarding multiple regimes are normally conservative due to different combinations in the formation of treatment regimes. In this article, we propose a simultaneous confidence interval method to identify treatment regimes that are significantly different from the bulk of the treatment combinations. The new method is applied to analyze the dynamic treatment regimes (DTRs) prostate cancer trial which includes treatment combinations of four chemotherapies at multiple stages. The new method detects a discernible effect of the regime taxane–estramustine–carboplatin (TEC) followed by cyclophosphamide, vincristine, and dexamethasone (CVD), when it is compared with other four regimes starting with CVD.     

An investigation into a new class of vehicle routing problem with backhauls

A new version of the vehicle routing problem with backhauls is presented. In this new problem backhauls are not restricted to be visited once all linehaul customers have been served, neither are backhaul customers fully mixed with linehaul customers. In this problem the user based on his or her experience, the vehicle capacity, the type of products and the type of vehicle used, can define the position along a route from which the first backhaul customer may be visited. An insertion-type heuristic is put forward for this class of problems. An analysis of the improvement in route cost obtained by allowing a relaxation in the restriction of the mix of linehaul and backhaul customers is reported.     

浅谈启发式教学方法在“管理学基础”课程中的运用

教学界一直倡导将启发式教学方法运用于实践操作中去。而在不同科目和层次的课程中,其具体的方法又是多样的。以"管理学基础"为例,探讨启发式教学方法的运用。根据该课程的特点,主要可以采用巧妙设置问题、适当引入相关的经典案例、与实践活动环节相互结合等途径来达到启发式教学的良好效果。
