走马楼吴简字词札记

走马楼吴简为汉语史研究提供了一定数量难能可贵的崭新而真实的同时材料.对其进行语言研究,有助于吴简的进一步整理利用,也可以加深我们对中古文献的阅读理解,对于大型语文辞书的编纂修订也有较大的参考价值.结合相关文献对其中的字词进行考察,发现:作为官方登录户籍的固定用语,“口食”表示“家口”的用法出现得虽比“食口”早,但最终为后者所取代;秦汉时期,高年女子一般称作“大女”,到晋代,“老女”之类的称呼才在简本、纸本户籍中大量出现,因此,吴简中“大女”、“老女”交互使用的现象十分独特;先秦到三国时期,“户人”充当“一户之主”义在各类典籍和文书中经见,后来为“户主”一词取代,“户人”一词则发生意义转移,泛指“一户之人”、“一户之民”.     

The Effect of Tax Policy Choices on the Labor Market on the Perspective of Global Governance

Tax policy transition plays a very important part in global governance, not only for the public operation or social equity, but also for the labor market which is firmly related with social welfare. On the other hand, unemployment has become a serious problem in 2008. Our research focused on the influence of different tax policies on the adjustment of unemployment, and the transition between direct and indirect taxation. This paper starts with conceptual discussion of the theoretical mathematical model and empirical analysis, and finally policy suggestion. Our conclusion varies due to the initial tax policy, but briefly we suggest that direct tax is more beneficial in the job market than indirect tax.

Triple-solution approach for the strip packing problem with two-staged patterns

A triple-solution approach for the rectangular level strip packing problem is presented, where m item types with specified demands are packed in levels into a strip with definite width and infinite height to minimize the occupied height, with the constraint that the items in the same level cannot be placed one on top of the other. The approach contains two phases and considers three types of solutions. In phase one, two types of solutions, obtained respectively from solving residual problems using column generation and from looking ahead, are considered and the best is selected as phase-one solution. In phase two, an integer programming model is solved over the levels generated in phase-one to obtain phase-two solution. Finally the better one of the phase-one and phase-two solutions are selected. Computational results indicate that the approach is effective for both the instances with strongly heterogeneous items and those with weakly heterogeneous items.     

On the vertex cover $$P_3$$ problem parameterized by treewidth

Consider a graph G. A subset of vertices, F, is called a vertex cover \(P_t\) (\(VCP_t\)) set if every path of order t contains at least one vertex in F. Finding a minimum \(VCP_t\) set in a graph is is NP-hard for any integer \(t\ge 2\) and is called the \(MVCP_3\) problem. In this paper, we study the parameterized algorithms for the \(MVCP_3\) problem when the underlying graph G is parameterized by the treewidth. Given an n-vertex graph together with its tree decomposition of width at most p, we present an algorithm running in time \(4^{p}\cdot n^{O(1)}\) for the \(MVCP_3\) problem. Moreover, we show that for the \(MVCP_3\) problem on planar graphs, there is a subexponential parameterized algorithm running in time \(2^{O(\sqrt{k})}\cdot n^{O(1)}\) where k is the size of the optimal solution.     

劳动合同法下企业制度差异对员工的分流机理及企业签订合同的临界值研究

固定合同期限的长期化虽然加大了企业在签订员工时的用工风险,但并不意味着《劳动合同法》不利于企业的发展。本文运用博弈分析方法,从企业制度角度对该问题进行研究,提出了一种劳动者分流现象及企业签订合同的临界值p,该现象不仅可以促进企业不断完善制度,还能促使劳动者不断提高自身素质,从而有利于我国企业竞争力及劳动者整体素质的提高。所以,《劳动合同法》不仅不会阻碍企业的发展,反而对企业的长远发展有不可替代的促进作用。

基于SCOR的物流作业成本核算模型

结合物流成本核算的要求,综合运用成本计算领域和供应链领域的最新理论,即作业成本法和SCOR模型,构建了基于SCOR的物流作业成本核算模型(ABC-SCOR模型),通过定义标准的物流作业分析流程,使物流作业成本核算的可操作性得到加强。最后,运用一案例进一步说明该方法的具体操作方法。     

论社会主义政治文明建设与反腐倡廉

本文从社会主义政治文明建设的高度认识反腐倡廉,深入研究二者之间的关系。提出社会主义政治文明命题的提出是对马克思主义政治学说的新发展,社会主义政治文明建设为反腐倡廉提供了战略支撑和辟开了新的路径,反腐倡廉是社会主义政治文明建设的重要保证。     

科技新闻写作创新谈

当前,一些高等学校校报科技新闻的写作还停留在仅仅报道高等学校科研成果表面的“老套子”中,写作者的头脑缺乏意识创新、写作缺少技巧创新,在发现科技新闻线索、挖掘新闻深度和表现新闻价值等方面还存在较大的不足。高等院校新闻采写的创新,尤其是科技新闻写作的创新,已是大势所趋。
