基于区块链的文件存储碎片分配优化模型

为了改善原有碎片分配方案仅以节点响应效率为主而对节点分配次数、节点空间利用率、安全性能欠缺考虑的现状,提出分布式文件存储系统的碎片分配优化模型。优化模型由节点响应状况检测、大范围节点数据完整性审计和包含剩余存储空间大小、最近存储碎片时间戳以及响应时间长短的综合评估3方面构成。对其进行仿真实验,对比原有方案,优化方案没有出现节点倾斜现象,选取次数最大落差不超过95;节点效率得到了均衡,最大落差缩减至15%。优化方案提高了碎片分配的公平性、安全性和可靠性,实现了最优节点的自动化选择。     

大学生职业声望评价研究

运用自编的大学生职业声望问卷对河南省近千名大学生进行问卷调查，结果发现，大学生最为欣赏的十种职业依次为：白领人员，企业管理人员、军人、公公司经理、企业策划人员、厂长、信息分析人员、大学教师、工程师和律师。不同专业、性别、生源、年级间职业声望评价差异较小，但在具体职业上存在差异。表现出职业声望评价共性与个性的统一。     

Organizational Identification: A Mixed Methods Study Exploring Students’ Relationship with Their University

Organizational identification (OID) is the outcome of social construction processes in which individuals define themselves in terms of their organizational membership. Students’ identification with their university reflects value congruence with the institution and is reflected in communication. Drawing on social identity theory (SIT) and utilizing quantitative and qualitative data from students (n = 555), we found relationships between OID and construed external image of the university, trust in the university, satisfaction with the university, perceived interorganizational competition, and outcomes, including intended future involvement. Students were re-surveyed nine months later (n = 397, with 83 respondents matching Time 1 and Time 2) to assess their OID stability. Open-ended responses describe situations and events that strengthen/lessen OID. We offer implications for OID, SIT, and for organizational communication research and practice.     

University reputation and undergraduates’ self-perceived employability: mediating influence of experiential learning activities

ABSTRACT

Stratification, in the form of silent exclusion that is experienced by some groups of students because of the perceived low reputation of the university attended, and which the students have no control over, has been observed as a social menace that works against the concept of equity in education. To address this problem, a need exists for universities with lower reputations to go the extra mile to develop the employability skills of their students, which, in turn, will enhance their self-perception of employability. The major objective of this study was to investigate the influence of experiential learning activities on the relationship between university reputation and self-perceived employability among undergraduates in South African universities. Data were collected by means of an adapted questionnaire from 402 respondents drawn from two universities in the same province in South Africa. To achieve our objective, four hypotheses were formulated and tested through Structural Equation Modelling (SEM) using AMOS 25. The findings show that both direct and indirect effects of university reputation on undergraduates’ perceived employability through experiential learning activities are positively significant. To minimise the negative effects that universities with low reputations are likely to have on undergraduates’ acquisition of experiential learning, on their self-perceived employability, and subsequently on their employment prospects, the government, the Department of Higher Education and universities (particularly, the low-rated ones in South Africa) need to put in place some timely interventions, some of which are suggested in the study.

论我国大学跨学科研究的三重障碍及其突破

我国大学的跨学科研究面临三重障碍:组织结构的院系隔离和跨学科学位的欠缺造成组织障碍;僵化的人事制度和评价制度构成制度障碍;以学科分化为基础的管理体制、学术评议中的"本位主义"造成资源障碍.有鉴于此,必须促进大学跨学科研究组织的多元化,成立跨学科专家委员会、信息办公室等机构以提供组织支持;必须采用固定和流动相结合的人事制度、相对灵活的考核与激励机制以提供制度支持;必须加强校级统筹以促进资源共享、设立跨学科研究发展基金以提供资源支持.     

声誉损失对会计师事务所市场份额影响的实证研究

会计师事务所规模是否与审计质量成正比？声誉说认为会计师事务所规模越大,审计质量越高。而诉讼威胁论则认为只有在法制环境足够健全时,会计师事务所规模才与审计质量正相关。文章利用我国2003-2010年的上市公司审计数据检验了声誉损失对会计师事务所份额的影响,未能发现有系统性的证据支持声誉说。分析表明,在受到证监会处罚的事务所并没有出现系统性的失去客户或被迫降低审计收费的情况出现。鉴于这种情况,结合我国法制环境比较薄弱的现实,在将事务所规模与审计质量成正比的理论应用到我国审计市场时,应作特别谨慎的检验。
