大学生社会主义核心价值体系教育现状的调查与分析

在广东理工职业学院和广东技术师范学院的大学生中进行的有关大学生社会主义核心价值体系教育现状的问卷调查显示,大学生总体上重视对社会主义核心价值体系的学习,基本上能够认同、赞成社会主义核心价值体系,只有极少数大学生存在错误思想和信仰危机,在个人价值观和道德判断上出现了迷茫和偏差;但大多数大学生对于社会主义核心价值体系的践行...     

南宋高宗年间镇抚司研究

高宗建炎四年五月,为抵御金人南侵,南宋在宋金边境设立了众多的藩镇——镇抚司.镇抚司的割据性很强,但镇抚司的设置并未导致南宋最终出现类似唐代藩镇尾大不掉的局面.绍兴五年四月,诸镇抚司尽罢.通过设置镇抚司,南宋王朝最终稳定了统治,其废罢同时,也是绍兴十一年收夺大将兵权前的一次成功预演.

FARMER: A novel approach to file access correlation mining and evaluation reference model

File semantic has proven effective in optimizing large scale distributed file system. As a consequence of the elaborate and rich I/O interfaces between upper layer applications and file systems, file system can provide useful and insightful information about semantic. Hence, file semantic mining has become an increasingly important practice in both engineering and research community. Unfortunately, it is a challenge to exploit file semantic knowledge because a variety of factors could affect this information exploration process. Even worse, the challenges are exacerbated due to the intricate interdependency between these factors, and make it difficult to fully exploit the potentially important correlation among various semantic knowledges. This article proposes a file access correlation miming and evaluation reference (FARMER) model, where file is treated as a multivariate vector space, and each item within the vector corresponds a separate factor of the given file. The selection of factor depends on the application, examples of factors are file path, creator and executing program. If one particular factor occurs in both files, its value is non-zero. It is clear that the extent of inter-file relationships can be measured based on the likeness of their factor values in the semantic vectors. Benefit from this model, FARMER represents files as structured vectors of identifiers, and basic vector operations can be leveraged to quantify file correlation between two file vectors. FARMER model leverages linear regression model to estimate the strength of the relationship between file correlation and a set of influencing factors so that the “bad knowledge” can be filtered out. To demonstrate the ability of new FARMER model, FARMER is incorporated into a real large-scale object-based storage system as a case study to dynamically infer file correlations. In addition FARMER-enabled optimize service for metadata prefetching algorithm and object data layout algorithm is implemented. Experimental results show that is FARMER-enabled prefetching algorithm is shown to reduce the metadata operations latency by approximately 30%–40% when compared to a state-of-the-art metadata prefetching algorithm and a commonly used replacement policy.

Implementation of advanced peripheral bus interface for MV1O MCU

MV10 is an MCU which consists of PWM,ADC,CAN and some other function blocks.It is designed for car body's control.Advanced peripheral bus (APB) is a low speed AMBA bus connecting low-power peripherals.This paper presents an implementation of APB interface for MV10 MCU.After that,MV10 can be integrated into any AMBA system on chips (SoCs) easily.We have built a multi-core system with ABMA to verify this design.In this system ARM9 is a main processor mounted on AHB and MV10 acts as a low-power and low-speed slaver on APB.Before building this system,some operations are encapsulated into a task with dedicated ID.MV10 works as a co-processor with ARM by acquiring task ID from ARM.The result of simulation indicates that MCU can work well as expected.Based on our design,MV10 can be mounted on any AMBA system from now on.     

Global existence and blow-up of solutions to reaction-diffusion system with a weighted nonlocal source

In this paper, we study a semi-linear reaction-diffusion system with a weighted nonlocal source, subject to the null Dirichlet boundary condition. Under certain conditions, we prove that the classical solution exists globally and blows up in finite time respectively, and then obtain the uniform blow-up rate in the interior.

中国的城市化与土地制度改革

我国宪法一方面规定城市的土地归国家所有,农村的土地归集体所有,这就意味着无论是公益性还是非公益性土地需求,都必须通过国家的征地行为来满足,必须先变成国有;另一方面《宪法》又明确表明,国家只有出于公共利益的需要,才能对农地进行征收或者征用。现行征地制度中存在着这个二律背反,应进一步创新和完善城市国有土地制度改革和农村集体土地制度改革的基本思路,尤其要重视研究解决城乡建设用地增减挂钩中土地增值的分配、城市化与土地适度规模经营以及农民增收的关系、城乡宅基地同权同价以及粮食安全责任分摊等问题。
