知识图谱视角下中国循环经济研究动态分析

以CSSCI数据库中收录的主题为循环经济的相关文献为研究对象,运用CiteSpaceⅢ软件进行知识图谱分析,分别制作了时空分布、文献共引和关键词共现知识图谱,以探究循环经济研究的分布状况、变化趋势和热点领域。研究发现:2001年以来循环经济方面的文献在数量上呈整体上升趋势并于2005年达到顶峰;《环境保护》刊登相关文献数量最多;该领域引用的外文期刊主要有《Journal of Cleaner Production》等;冯之浚教授为中国循环经济研究领域最多产的学者;循环经济生态机理、发展模式、技术支撑及发展保障是主流研究领域;研究发展路径为从认识循环经济核心内容、出台相关法律来推动循环经济的实施以及到循环经济的深化发展。     

Likelihood-based inference for the transmuted log-logistic model in the presence of right-censored data

Although new transmuted distributions have been widely proposed in the last few years, it is rarely to find those class of models applied in survival analysis in the presence of censored lifetimes. In this context, we are concerned in applying the transmuted log-logistic model in the study of discharge times of patients treated with the Linezolid drug. For model fitting, we use and compare different profile likelihood methods. Analysis of residuals and influence are also presented. All results are validated in a simulation study by considering the bootstrap techniques.     

Flood risk mapping and analysis using an integrated framework of machine learning models and analytic hierarchy process

In this study, a new approach of machine learning (ML) models integrated with the analytic hierarchy process (AHP) method was proposed to develop a holistic flood risk assessment map. Flood susceptibility maps were created using ML techniques. AHP was utilized to combine flood vulnerability and exposure criteria. We selected Quang Binh province of Vietnam as a case study and collected available data, including 696 flooding locations of historical flooding events in 2007, 2010, 2016, and 2020; and flood influencing factors of elevation, slope, curvature, flow direction, flow accumulation, distance from river, river density, land cover, geology, and rainfall. These data were used to construct training and testing datasets. The susceptibility models were validated and compared using statistical techniques. An integrated flood risk assessment framework was proposed to incorporate flood hazard (flood susceptibility), flood exposure (distance from river, land use, population density, and rainfall), and flood vulnerability (poverty rate, number of freshwater stations, road density, number of schools, and healthcare facilities). Model validation suggested that deep learning has the best performance of AUC = 0.984 compared with other ensemble models of MultiBoostAB Ensemble (0.958), Random SubSpace Ensemble (0.962), and credal decision tree (AUC = 0.918). The final flood risk map shows 5075 ha (0.63%) in extremely high risk, 47,955 ha (5.95%) in high-risk, 40,460 ha (5.02%) in medium risk, 431,908 ha (53.55%) in low risk areas, and 281,127 ha (34.86%) in very low risk. The present study highlights that the integration of ML models and AHP is a promising framework for mapping flood risks in flood-prone areas.     

中国共产党国际宣传工作研究的知识图谱分析

国际宣传工作历来是党的一项重要工作。随着中国国际地位不断提高,在国际事务中发挥的作用越来越大,党的国际宣传工作越来越受到重视,学界的关注度和相关的研究成果数量也逐年上升。学界对党的国际宣传工作的理论与实践展开了研究,形成了一些有代表性的成果,推动了相关理论研究不断走向成熟,但是仍然存在相对薄弱之处。为了揭示目前学界关于中国共产党国际宣传工作研究的现状、热点、发展趋势及现有研究的不足之处,以CiteSpace 6.1.R2作为研究手段,以2002-2022年中国知网(CNKI)数据库检索的418篇有效文献为数据基础进行计量分析,绘制相关知识图谱,通过分析知识图谱和梳理现有文献得出结论,并据此提出研究建议,以期为未来该领域的研究提供参考与借鉴。     

法国现象学或实存与知识的张力

现象学在法国的引进与发展包含了主体哲学和概念哲学的共同努力。在主体哲学和概念哲学之间存在着复杂的关联,这意味着实存论与知识论之间巨大的张力。现象学在20世纪法国哲学中占据着主导地位,但现象学有着复杂多样的形态,出现了从意识现象学到身体现象学再到物质现象学的演变。     

A card game to renew urban parks: Face-to-face and online approach for the inclusive involvement of local community

Urban parks are often designed and renewed using standardized models that fail to incorporate the different functions and services required by the local communities served. Furthermore, when the citizens are involved in co-design, the participation processes are seldom fully inclusive, and the results are not representative of the entire local community. The paper starts from these considerations for developing an innovative participatory design method to renew urban parks. This method simultaneously uses multiple and alternative participation tools for adapting to the different technical skills of the citizens and to their inclinations. Furthermore, it entails the analysis and interpretation of the expectations of the local community in light of the urban green network. The method uses the conceptual framework of the SWOT analysis and the Trochim's concept mapping for developing a card game playable face to face or online. The results of the card game are processed using the statistical analysis to identify the main design themes (the clusters), and to split the participants’ suggestions into different design alternatives. Successively, the participants vote these alternatives for selecting the renewal design respondent to the local community's needs.     

科学发展观研究的基本特点、实践运用及其未来走向

Urban ecosystems: What would Tansley do?

The ecosystem concept was introduced in ecology originally to solve problems associated with theories of succession and ecological communities. It has evolved to become one of ecology’s fundamental ideas, and has proven to be applicable to a wide variety of research questions and applications. However, there is controversy about whether or how well the ecosystem concept is suited to urban habitats. By examining Arthur Tansley’s original presentation of the ecosystem concept, and exploring how the ecological context of the concept has changed, we indicate that the fundamental concept of the ecosystem is well suited to urban ecological studies. The concept can be clarified for urban use by including a social complex and a built complex to insure that human social institutions and actions, and the structures and infrastructure they build are explicitly included in the ecosystem concept. The ecosystem concept is thus seen as clearly robust to use in urban areas.

Benefits of cultural matching in foster care

Sixty-one foster parents from a central Canadian province participated in a telephone interview that included the question: “What are the benefits of fostering children who have the same values, beliefs and traditions as you?” A total of 51 unique responses were obtained and grouped together by 13 foster parents. Multidimensional scaling and cluster analysis were used to analyze the grouping data. Foster parents described five themes: expand on held values, child feels secure, smooth transitions, low stress and more in common. There were similarities and differences between the perspectives of foster parents interviewed and the literature. Implications for future research are discussed.     

析黑格尔的"具体真理"

文章阐明黑格尔的"具体真理"是完全的唯心主义,但其又有合理的因素,即深刻地揭示了真理的具体性就在于它的辩证性,主要表现为三个明显的特点:真理是"多样性的统一";真理是普遍性和特殊性的统一;真理是"对立面的统一".
