现实世界不确定性的哲学意蕴     

欧庭高  陈多闻 《山西师大学报(社会科学版)》2004,31(3):12-17

不确定性是普遍存在的,是现实世界的本质属性。人类的实践和认识活动并不仅仅在于追求确定性,更重要的是消除不确定性。不确定性渗透在人类的思想、行动之中,是各种理论的前提和基础。它根源于客观事物或过程自身和认识主体以及认识主体与客体之间的复杂关系中,具有本体论与认识论的含义。  相似文献

AIS数据对两船会遇中自动避碰决策的影响初探     

陶源 《上海海事大学学报》2002,23(3):27-31

通过分析AIS技术所提供的他船数据的性能和作用 ,提出了解决长期困扰自动避碰决策技术发展的两个问题 (即他船信息来源的可靠性问题和船舶间航行、避碰意图互相通报的问题 )的办法。还提出了将AIS作为自动避碰决策系统的他船数据信息来源的设想 ,并分析了这种设想的可行性。介绍了在AIS数据的支持下 ,上述困扰自动避碰决策技术研究多年的两个问题得到解决的情况 ;分析了AIS数据中的新信息 ,例如他船状态信息 (操限船、失控船、限于吃水船等 )和他船避碰意图发现的新方法 (实时监控他船动向 )等AIS优于ARPA的数据功能对于自动避碰决策的作用 ,并研究了其应用方法  相似文献   

研究生学术搜索中的信息规避行为与成因研究     

金燕  刘琦  毕崇武 《图书情报工作》2022,66(18):84-94

[目的/意义]探索研究生学术搜索中的信息规避行为及成因,为改善信息规避消极影响、提升学术搜索效果提供依据。[方法/过程]首先利用任务式搜索实验获取搜索行为数据;其次通过访谈、扎根理论编码析出各搜索环节的信息规避行为及其影响因素;然后结合实验和访谈归纳出信息规避行为引发的搜索模式及搜索路径;最后依据SOR理论构建不同搜索模式下的信息规避模型,并结合问卷调研分析各搜索环节的信息规避成因。[结果/结论]研究生学术搜索中的信息规避行为受任务、信息、环境、资本因素外部刺激,受心理因素内部驱动,受能力因素调节控制;信息规避行为引发了直线式和螺旋式 2种搜索模式,在心理因素的反作用下,螺旋式搜索模式是对直线式搜索模式下信息规避行为负面影响的主观矫正;信息规避行为有积极和消极之分,需要引导消极信息规避行为,减少其带来的不利影响。  相似文献   

Relationship transitions for parents of children with autism spectrum disorder: types,turbulence, and transition processing communication     

Kellie St.Cyr Brisini  Denise Haunani Solomon 《Journal of Applied Communication Research》2018,46(4):447-468

This study surveys transitions specific to parents of children with autism spectrum disorder (ASD), examines how aspects of relational turbulence vary based on the type of transition experienced, and explores the transition processing activities couples use to navigate marital transitions in this context. The study examined the transition experiences of 298 parents of children with ASD who were currently married. Participants detailed an important transition throughout the life span of their child with ASD using open-ended questions. They completed scales assessing qualities of the relationship during the transition and transition processing communication used to navigate the experience. Results demonstrate significant differences in experiences of relational turbulence based on the type of transition described. In particular, the initial diagnosis received the highest ratings for transition magnitude and relational turbulence compared to other common transitions. Engagement in transition processing communication predicted relational uncertainty and facilitation from a partner, which predicted relational turbulence.  相似文献   

Relational turbulence and perceptions of partner support during reintegration after military deployment     

Leanne K. Knobloch  Erin D. Basinger  Jennifer A. Theiss 《Journal of Applied Communication Research》2018,46(1):52-73

The transition from deployment to reintegration can be stressful for returning military personnel and at-home partners, and support plays a key role in their ability to transition effectively. We draw on relational turbulence theory to advance predictions about how parameters of the relationship between returning service members and at-home partners predict their perceptions of their partner’s support during the post-deployment transition. We surveyed 235 individuals (117 returning service members, 118 at-home partners) who had experienced the transition within the past 6 months. Findings consistent with the theory indicated that relational turbulence partially mediated the negative associations that relational uncertainty and interference from a partner shared with partner support. Partner uncertainty was a direct negative predictor of partner support as well. We consider how these results extend theory, research, and practice.  相似文献   

Mapping the educational experiences of children with pathological demand avoidance     

Emma Gore Langton  Norah Frederickson 《Journal of Research in Special Educational Needs》2016,16(4):254-263

‘Pathological demand avoidance’ (PDA) describes a pattern of difficulties increasingly recognised as forming part of the autistic spectrum. Although clinical reports suggest that children with PDA are likely to experience considerable difficulties in education, their educational experiences have not yet been explored in any systematic way. In the current study, 42 parents of children with PDA completed a questionnaire about their child's educational experiences. Parents' responses indicated that this group of children displays high levels of problem behaviours in school, and receives corresponding high levels of special educational need support and professional involvement. Despite this support, the group had experienced high rates of exclusion and placement breakdown, with only 48% now in mainstream education. Parents reported relatively high satisfaction in their children's educational placements, with success defined by parents in terms of child outcomes, school characteristics and PDA‐specific factors. Findings are discussed with reference to what is known about the educational experiences of children with more typical autism spectrum conditions and in terms of the implications for the inclusion of this group of children with complex needs.  相似文献   

交换视角下体育公共服务治理中的问题与对策分析     

朱传客  童莹娟  刘玉洁 《武汉体育学院学报》2017,51(3):16-21

基于交换理论，以交换理性、交换结构、交换的不确定性为切入点，结合相关治理案例，对体育公共服务治理中的公共性偏移、合作性缺失、多元化不足等问题进行解释。研究认为，在体育公共服务治理中，当经济理性超过社会理性，各主体将形成损公利私的扭曲行为；资源状况的差异导致主体结构失衡，进而导致主体间形成控制与依附的关系，阻碍了以平等、协作为特征的主体间合作形成；不确定性影响了“体制外”组织的参与，导致“多元化”的不足。最后，以培育社会理性、平衡主体结构、降低不确定性三个角度出发，以规范各主体行为为抓手提出治理策略与建议。  相似文献   

Trait Affection Given and Received: A Test of Hofstede’s Theoretical Framework     

Daniel H. Mansson  Aldís G. Sigurðardóttir 《Journal of Intercultural Communication Research》2017,46(2):161-172

This study sought to address Hofstede and McCrae’s (2004) call for systematic cross-cultural comparisons of trait-like attributes. Specifically, we examined the extent to which Danish, Icelandic, Polish, and American adults’ trait affection given and trait affection received are (a) dependent on national origin, and (b) associated with Hofstede’s dimensions of cultures (i.e. individualism-collectivism, masculinity-femininity, power distance, and uncertainty avoidance). The participants (N = 606) completed a questionnaire in English that consisted of the trait affection given and trait affection received scales. Results of a multivariate analysis of variance and linear regression analyses revealed that people’s trait affection given and received are (a) dependent on national origin, and (b) associated with Hofstede’s dimensions of cultures.  相似文献
