词的离合现象是语法研究中的老大难问题。文章独辟蹊径,从与词的离析使用密切相关的准定语和准名词入手,根据句子的信息结构原则,解释了词的离合现象的成因。文章指出,话语的信息结构安排是促成句法结构重组的语用推力:话题语的指称化处置诱发了准定语结构的操作,基本不涉及词的离析;评述语受单一新信息原则制约而出现的事件化处置,迫使及物性低的双音词强行拆分以容纳事件化所需要素,是诱发词的离析并催生准定语和准名词的直接动因。文章的观点是,用朴素的眼光看汉语,汉语中并无什么离合词,词的离合只是非形态语中双音词的用法变异,是语用型语言句子信息结构进行整编与重组的副产品。  相似文献

扶贫开发是国家治理的重要内容,有着丰富的政治意涵,展示着执政党执政、政府治理的基本过程和价值归属。中国的扶贫工作带有着明显的运动式、项目制、压力型的色彩,在取得巨大成效的同时,也有着走向无序化、无效化的风险。以现代国家建设和政党建设的基本理念,构筑多中心的贫困治理格局,建立现代化的扶贫开发的制度体系,走向法治化、制度化、民主化、规范化是扶贫开发的治本之策。  相似文献

迄今,为解决多属性偏好关联决策属性集容量判断指数复杂性难题所提出的λ模糊测度模式与k-可加模糊测度模式,以及建构在它们之上的属性集容量确定的推算模型,尚存在着适用性差的技术不足。为此,以平衡容量判断的可操作性和容量推算的准确性为视角,提出了一种新容量测度模式,即关于容量判断与推算的夹挤式测度模式,并在此基础上通过引入决策者较易判断给出的容量序信息构建了相应的容量推算模型。基于数值模拟的对比分析表明:新模式不仅在应用可行性上高于k-可加模糊测度模式,而且从容量推算的准确性上看也明显优于λ模糊测度模式和k-可加模糊测度模式,因而对实际决策具有更强的适用性。  相似文献

Undergraduate career planning courses have shown efficacy in decreasing students’ negative career thoughts; however, universities have minimally applied these courses to science, technology, engineering, and math (STEM) populations. This study compared the influence of a STEM‐focused career planning course for undecided STEM students with a seminar course for decided STEM majors. An analysis of covariance with covariate adjustment revealed that undecided career planning students had lower adjusted mean scores on a measure of negative career thinking than the decided STEM majors after the first semester of college. The results provide support for the efficacy of STEM‐focused career planning courses and measuring negative career thoughts with STEM undergraduates.  相似文献

当代知识论越来越重视认知价值的研究,但从认知价值角度去重新思考传统怀疑主义问题的研究却很少。历史上的怀疑主义者既认为我们无法拥有任何知识,又主张我们应该悬置判断。因此,他们不仅预设了一个高的知识标准,而且预设了一个价值标准:任何达不到知识标准的认知状态都是没有认知价值的。但这个价值标准是错误的,所以我们即使无法达到怀疑主义者所设定的知识标准,也不必悬置判断。假设怀疑主义者认为我们无法拥有任何知识,同时认可“有些达不到知识标准的认知状态也有认知价值”,那么怀疑主义就没有很大的威胁性,因为即使我们无法获取知识,也可以获得具有认知价值的东西,取得认知进步。此外,摩尔主义、语境主义、溯因主义这几种对怀疑主义的主要回应是否成功,最终都依赖于对认知价值的讨论。  相似文献

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

Objectives

The aim of this project is to determine, assess and identify the real impact of breastfeeding support networks in Murcia (Spain).

Methods

After searching unsuccessfully for a validated questionnaire, a specific one was developed and validated for measuring the impact of formal and informal support networks through five dimensions: satisfaction, consultation, experience, problems and support. The questionnaire was provided to 500 mothers with experience in breastfeeding, who brought their children to baby paediatricians between 2 June and 27 November 2014. Upon completion of the survey and fieldwork, a detailed statistical analysis was conducted.

Results

The degree of satisfaction perceived by the users of the services of support breastfeeding networks is remarkable. In addition, mothers who clarified their doubts and discussed their problems with health professionals and/or breastfeeding support networks were more likely to breastfeed for a longer duration compared to those who did not (p = 0.005). Furthermore, mothers who sought support in breastfeeding are more likely to breastfeed for more than 6 months (p < 0.0005).

Conclusion

Based on this information, we conclude that breastfeeding support networks have a positive influence in the duration of a women’s decision to breastfeed.  相似文献

This paper introduces a systemic methodology for reviewing professional responses to abuse between young people. The approach, “contextual case reviewing,” draws upon constructivist structuralism to assess the extent to which safeguarding practices engage with the social and public contexts of abuse. The paper conceptually compares the methodologies of contextual case review and other serious case review methods before drawing upon findings from 2 studies, which used the contextual case review methodology to explore the extrafamilial nature of peer‐on‐peer abuse and the ability of child protection practices to engage with this dynamic. Thematic findings from these studies regarding the practical interpretation of “significant harm” and “capacity to safeguard,” as well as their use within child protection assessments, are used to challenge conclusions of other case reviews, which imply that child protection procedures are sufficient for safeguarding young people. Contextual case reviews suggest that safeguarding practices, and the legislation that underpins them, are culturally, procedurally, and organisationally wedded to the context of the home, whereas insufficiently engaged with extrafamilial contexts of significant harm. The application of these issues require interrogation if social work systems are to provide sufficient mechanisms for safeguarding young people and families at risk of significant harm.  相似文献

ABSTRACT

Scientific research of all kinds should be guided by statistical thinking: in the design and conduct of the study, in the disciplined exploration and enlightened display of the data, and to avoid statistical pitfalls in the interpretation of the results. However, formal, probability-based statistical inference should play no role in most scientific research, which is inherently exploratory, requiring flexible methods of analysis that inherently risk overfitting. The nature of exploratory work is that data are used to help guide model choice, and under these circumstances, uncertainty cannot be precisely quantified, because of the inevitable model selection bias that results. To be valid, statistical inference should be restricted to situations where the study design and analysis plan are specified prior to data collection. Exploratory data analysis provides the flexibility needed for most other situations, including statistical methods that are regularized, robust, or nonparametric. Of course, no individual statistical analysis should be considered sufficient to establish scientific validity: research requires many sets of data along many lines of evidence, with a watchfulness for systematic error. Replicating and predicting findings in new data and new settings is a stronger way of validating claims than blessing results from an isolated study with statistical inferences.  相似文献

As numbers of families with same-sex parents increase in the United States, children are more likely to encounter diverse family structures. Given that young children can demonstrate in-group bias, prejudicial attitudes, and social exclusion, it is important to understand how children perceive their peers in diverse families. To our knowledge, no studies have assessed elementary-school-age children's attitudes about same-sex parent families. Here, 131 elementary school students (Mage = 7.79 years; 61 girls) viewed images of same-sex (female and male) and other-sex couples with a child and then were asked about their perceptions of these families, particularly the children. Results indicated participants' preferences toward children with other-sex versus same-sex parents. Developmental and practical implications about children's attitudes toward sexual minority parent families are discussed.  相似文献
