诗人张枣一生仅仅创作了百余首诗歌,但在这些为数不多的作品中,关于传统,他始终有着一种相对明晰的态度。本文选择以声音的视角切入,将通过句式、停顿、词的选择等包孕在情感与意象中的内在化节奏展开,从而在声音传统中去洞悉张枣的诗歌所彰显出的哀鸣与急促等情感特征。  相似文献

本案例中,大学的规章制度与组织结构规定了参与旧房改造项目相关决策的群体和机构以及做出相关决策所需要的步骤与程序,也规定了不同群体在这一决策过程中的不同地位和可能拥有的资源,甚至是他们的决策倾向;旧房改造项目的冲突根源在于计划经济体制向市场经济体制转型过程中大学内部出现的不同群体的利益分化,但值得注意的是,这些不同群体的利益冲突却是以质疑相关环节上决策者行为的合法性为中心展开的,而关于合法性的争议则更多地涉及了对相关行为的价值意义的解释。  相似文献

Story stem measures are an increasingly popular method for assessing the attachment representations of young children, but little is known of their cross‐cultural applicability. This study aimed to characterise the attachment representations in 73 five‐ to eight‐year‐old children in urban Ghana, West Africa, using the Manchester Child Attachment Story Task (MCAST) to test its feasibility, psychometric characteristics and concurrent associations with caregiver‐ and teacher‐rated child behaviour, and to conduct a qualitative thematic analysis of methodological observations. Among the classifiable cases (92 percent), all attachment classifications were observed, yielding a higher rate of secure attachment than in European samples. Inter‐rater reliability, internal consistency, and internal structure were reasonable and largely similar to European studies, although one structural difference was the separation of ‘child assuagement of distress’ from other secure‐related items. MCAST narratives were associated with teacher‐ and caregiver‐rated hyperactivity, but internal consistency was low in most Strengths and Difficulties Questionnaire scales. Possible culturally‐sensitive explanations for our psychometric and qualitative findings are discussed. Overall, story stems are a promising tool for accessing attachment representations in non‐Western samples, although modifications are likely to improve cross‐cultural equivalence when applied to non‐Western cultures. Further investigation is needed to link MCAST outcomes to parenting and socio‐emotional development.  相似文献

Despite the significance of relationship management in any information provision or exchange, public relations scholarship has typically focused on examining the underlying internal communication processes from a transactional perspective. These processes are frequently associated with organizational information dissemination, overlooking other critical contents to make strategic decisions. This study draws market information processing into the debate about internal communication, providing a greater understanding of how a relational approach can improve market intelligence dissemination. Results show that an effective management of market knowledge requires the use of such an approach, which in turn, cultivates the shared interpretation of market information and innovation performance. The findings stimulate fresh discussion about the nature and development of internal communication knowledge and practice.  相似文献

The internal conversation has a venerable place in the symbolic interactionist tradition but has been the focus of little empirical research by interactionists. After reviewing selected research on the internal conversation (most by noninteractionist sociologists or nonsociologists), we argue that interactionists ought to conduct research of our own to examine claims we have been making and to better understand social life. We propose some worthy areas and avenues of investigation.  相似文献

Prior information is often incorporated informally when planning a clinical trial. Here, we present an approach on how to incorporate prior information, such as data from historical clinical trials, into the nuisance parameter–based sample size re‐estimation in a design with an internal pilot study. We focus on trials with continuous endpoints in which the outcome variance is the nuisance parameter. For planning and analyzing the trial, frequentist methods are considered. Moreover, the external information on the variance is summarized by the Bayesian meta‐analytic‐predictive approach. To incorporate external information into the sample size re‐estimation, we propose to update the meta‐analytic‐predictive prior based on the results of the internal pilot study and to re‐estimate the sample size using an estimator from the posterior. By means of a simulation study, we compare the operating characteristics such as power and sample size distribution of the proposed procedure with the traditional sample size re‐estimation approach that uses the pooled variance estimator. The simulation study shows that, if no prior‐data conflict is present, incorporating external information into the sample size re‐estimation improves the operating characteristics compared to the traditional approach. In the case of a prior‐data conflict, that is, when the variance of the ongoing clinical trial is unequal to the prior location, the performance of the traditional sample size re‐estimation procedure is in general superior, even when the prior information is robustified. When considering to include prior information in sample size re‐estimation, the potential gains should be balanced against the risks.  相似文献

To examine the multiplicative consistency of interval fuzzy preference relations (IFPRs), this paper first analyzes the limitations associated with the previous consistency concepts. Accordingly, a new consistency concept is defined that is an extension of the crisp case and overcomes limitations in the previous concepts. Next, a linear programming model to judge the consistency of IFPRs is constructed, and an approach to derive multiplicative consistent IFPRs is introduced. Furthermore, goal-programming models to determine missing values in an incomplete IFPR are constructed that have the highest consistent level with respect to known values. Moreover, a multiplicative consistency and consensus based method for group decision making with IFPRs is developed that can address incomplete and inconsistent cases. Finally, two practical decision-making problems are offered to demonstrate the feasibility and efficiency of the new method, and an analysis of a numerical and theoretical comparison with several related methods is performed.  相似文献

钢板桩围堰合理的内支撑施工方案对施工安全、工期长短、成本大小均有一定的影响。以阜阳至六安铁路颍河特大桥深水基础超长钢板桩围堰施工实践为例,通过建立钢板桩、内支撑和土层相互作用的三维整体有限元模型,根据封底混凝土施工时机的不同,选择4种施工方案,对超长钢板桩围堰内支撑施工方案进行了探讨。结果表明:封底混凝土施工越早,对围堰结构的整体安全越有利;实际采用的施工方案要根据桥址处工程地质条件,结合实际工程情况,经方案比选和分析论证以后确定。  相似文献

对于“省管县”财政体制改革的认识,不能仅定位于压缩财政层级或县域政区财政脱困的权宜之计,必须将其提升至地方行政管理体制变革的高度。中国的财政管理体制改革必须在行政管理体制改革的大背景中找到自己的位置。本文认为,应逐步通过解除市领导县的管理体制,重新整合县域行政辖区,以及必要的省级行政区划的调整,在形成了一个相对合理地地方行政管理层级架构之后,方能营造出构建相对合理的地方政府间财政关系的可能性,进而使得“省管县”财政管理体制成为一种常态化的模式。  相似文献
