【目的】 提出用数学方法定量分析高校学报载文特征信息对其文献指标的影响,为优选稿件提供依据。 【方法】 以2005—2014年《中国矿业大学学报》载文特征信息和中信所、中国知网公布的期刊主要文献指标为样本,通过建立互信息（MI）对高校学报载文特征信息与高校学报文献指标的相关性进行定量分析;利用偏最小二乘（PLS）方法构建高校学报载文特征因子与文献指标的数学模型,然后引入MIV的计算策略,获得各载文因子对某文献指标MIV的累积贡献率(ACR)。 【结果】 高校学报载文学科因子的互信息MI值高于作者因子的互信息MI值,揭示优选学科方向是提升高校学报文献指标的关键;PLS模型能够准确地表达载文特征因子与文献指标之间的数学关系,与MIV策略相结合可有效评估载文特征因子对文献指标的影响。 【结论】 用基于互信息的直接分析方法和基于平均影响值模型评估的间接分析方法,有助于优选稿件以提升高校学报学术影响力。 相似文献

在处理开发和保护这一对矛盾时,传统作法是”自上而下”的简单方式,由于它忽略了基层土地用户的愿望,实施时困难重重,效果不佳。本文“交互式土地规划”的出发点是协调个体和群体的利益冲突：既考虑代表全社会利益的政府规划（自上而下）,又在具体规划中重视土地用户的切身利益（自上而下）,鼓励所有当事人的积极参与,既鼓励开发,又鼓励保护,因而具有许多优点,容易实施。 相似文献

Deep multi-view clustering (MVC) is to mine and employ the complex relationships among views to learn the compact data clusters with deep neural networks in an unsupervised manner. The more recent deep contrastive learning (CL) methods have shown promising performance in MVC by learning cluster-oriented deep feature representations, which is realized by contrasting the positive and negative sample pairs. However, most existing deep contrastive MVC methods only focus on the one-side contrastive learning, such as feature-level or cluster-level contrast, failing to integrating the two sides together or bringing in more important aspects of contrast. Additionally, most of them work in a separate two-stage manner, i.e., first feature learning and then data clustering, failing to mutually benefit each other. To fix the above challenges, in this paper we propose a novel joint contrastive triple-learning framework to learn multi-view discriminative feature representation for deep clustering, which is threefold, i.e., feature-level alignment-oriented and commonality-oriented CL, and cluster-level consistency-oriented CL. The former two submodules aim to contrast the encoded feature representations of data samples in different feature levels, while the last contrasts the data samples in the cluster-level representations. Benefiting from the triple contrast, the more discriminative representations of views can be obtained. Meanwhile, a view weight learning module is designed to learn and exploit the quantitative complementary information across the learned discriminative features of each view. Thus, the contrastive triple-learning module, the view weight learning module and the data clustering module with these fused features are jointly performed, so that these modules are mutually beneficial. The extensive experiments on several challenging multi-view datasets show the superiority of the proposed method over many state-of-the-art methods, especially the large improvement of 15.5% and 8.1% on Caltech-4V and CCV in terms of accuracy. Due to the promising performance on visual datasets, the proposed method can be applied into many practical visual applications such as visual recognition and analysis.

The International Network of Quality Assurance Agencies in Higher Education’s Guidelines of Good Practice by higher education
quality assurance agencies need substantial revision before they can be considered adequate by stakeholders in any national
higher education system. Various revisions are proposed in this article. But the International Network of Quality Assurance
Agencies in Higher Education also argues that adoption of its Guidelines of Good Practice has international significance in
that the decisions about higher education quality made by agencies which comply with them can be accepted at face value universally.
This conclusion, however, cannot be accepted until the Guidelines of Good Practice are amended to address the processes whereby
each agency can become comfortable with the criteria and standards which the others impose in their respective jurisdictions.
This article also maintains that, even if the Guidelines of Good Practice were technically perfect, agencies and/or governments
ought to subject any proposals for their implementation to the discipline of rigorous risk management processes.

孔子人性论所蕴含的矛盾引发了孟、荀的人性论之争。孟子的性善论和荀子的性恶论各有其特定的人性概念内涵,既在理论形式上互相对立,又在逻辑意蕴上互相补充。秦汉以降的人性论大多沿着调和孟、荀的路径发展。考察孟、荀的人性论,有助于我们正确反思当代中国人性沉沦与道德价值观冲突的实质、表现及其根源。 相似文献
