噪声环境中基于DTW的说话人识别

在VC++环境下,提取PLAR特征参数,基于听觉特性和语谱特性的语音增强器作为预处理器,对语音信号首先进行降噪处理,建立了基于DTW的抗噪声说话人识别系统.实验结果表明,即使在信噪比比较低的情况下,该系统都会在一定程度上提高多种噪声环境下说话人识别系统的识别性能.     

医药冷链物流在物联网环境下的动态风险评估

首先运用流程图法分析造成物联网环境下医药冷链物流各环节风险的众多因素源,并运用熵权法对风险指标客观赋权建立风险因素评估指标体系,然后利用Ge NIe软件建立动态贝叶斯网络模型对风险环节的关键风险因素进行概率评估。结果显示在风险评估中运输环节风险的发生概率最高,同时企业关于设备的验证选型是影响物联网医药冷链的关键风险因素,这为企业和政府控制药品质量安全管理提供了依据。     

军民科技资源共享博弈与治理研究

从经济、科研和制度三个方面,分析军民科技资源共享的基础条件,研究军民科技资源共享过程存在的现实困境。采用博弈理论方法,构建军民科技资源主体间的资源共享博弈模型,结果表明某一科技资源主体的预期共享收益(效用)不仅要高于其不共享科技资源时的收益,还与另一科技资源主体共享资源量、共享概率有关,并受到该主体对共享资源的吸收、利用能力影响。基于博弈分析结果和共享困境,从共享观念、法律制度、平台、标准体系、管理体制等方面,提出一系列的有效治理策略。     

The role of social media in the engagement and information processes of social CRM

This study furthers investigation into exactly how Social CRM (S-CRM) is different from traditional CRM, and models the interrelationships between its capabilities. It is underpinned in dynamic capabilities theory, to explain how social media, as a resource all organizations use, can lead to differing performance outcomes. It is underpinned in seminal research into traditional CRM, but which does not cater for the disruptive nature of social media. We outline how S-CRM is a second-order dynamic capability consistng of a set of first-order integrative dynamic capabiliies that, when properly interrelated, lead to performance outcomes. We particularly model the role of S-CRM front- and back-office technology capabilities, customer engagement initiatives, and social information processes in driving customer relationship performance. Findings show that S-CRM is different from traditional CRM in a range of ways in the front- and back-offices, and provide a framework for researcher and managers in information systems and marketing to operate at strategic and tactical levels within S-CRM, while being congisant of both.     

Digitally transforming work styles in an era of infectious disease

As a new perspective in this era of infectious disease confronting humanity (that cannot be avoided), and in light of research done to date, this article identifies the importance of exploratory research on the business and social impacts of “collaboration systems” which include video conferencing tools - important IT applications for companies. The article proposes analysis integrating four research streams on the digital transformation of work styles through collaboration systems.     

BHP:孤独症患者观点采择训练新方法

观点采择是个体社交能力的基础.关系框架理论RFT认为观点采择是一种操作性行为,其核心是包含人际、空间及时间三个维度的直证关系反应.基于RFT的评估和训练方案BHP采用多范例的方式来训练直证关系反应,从而促进观点采择.采用BHP方案训练孤独症儿童观点采择的多项研究发现,该方案能有效提升被试的观点采择能力,并有较好的维持和...     

行动、断言、事件和主体——动态道义逻辑的几个基本概念

1988年梅耶给出一个动态道义逻辑(DDL)系统,该系统不是处理一般的词项和命题,而是把行动和断言作为逻辑的处理对象。梅耶之后,这一系统不断完善,使得对于道义逻辑的讨论扩展到实施行动的主体,即行动者以及和行动者相关的事件。在此对DDL及其个体事件扩展进行粗略讨论,意在表明道义逻辑的探索,是一个不断地从抽象的一般道义范畴朝向具体的生活世界范畴的过程。     

自我决定理论视域下运动心理学课程思政改革创新研究

新时代高等院校的课程思政改革致力于深入挖掘专业课中的思想政治资源,有效发挥课堂育人的主渠道功能。在此目标指引下,体育类院校专业课程的课程思政改革势在必行,运动心理学是体育类高校体育运动类专业的本科骨干课程。动机的自我决定理论认为,人天生就有追求身心成长和能力发展的倾向,但需要环境提供持续的营养和支持。基于此,运动心理学课程思政从自我决定理论出发,立足于对学生个体特征和不同学习需求的分析,紧紧围绕如何满足其自主性、能力感和归属感来设计并实践激发和内化学生协同吸收专业知识和思政资源的动机环境,在具体教改中实现了5个方面的经验:以生为本,精心引入与专业深度融合的思政资源来激发动机的教学内容上的“精”;“师”是基础,着力构建专业教师团队确保课程思政教师队伍上的“专”;问号课堂,“问”出融会贯通专业知识和思政资源的教学过程上的“问”;活学活用,构建问题情境促进思政资源内化的教学设计上的“活”;知行合一,做中学,磨砺意志深度夯实思政教育的教学手段上的“实”。另外,要全面推进课程思政,还需注意完善教师全员育人的教学理念、着重分析学生的个性特征、打造多部门协同合作的“育人共同体”,以构建高校专业课课程思政改革的全员全程全方位育人体系。     

Sport-for-development: A comprehensive analysis of theoretical and conceptual advancements

Over the past decade, the field of sport-for-development (SFD) has experienced significant growth and diversification across research and practice. In this review paper, the authors provide a comprehensive analysis and discussion of the theoretical and conceptual developments within SFD, addressing a gap in the literature. Following a sport-focused review of SFD literature, the authors first identify five theoretical and conceptual frameworks that have emerged from within the SFD space. As a second step, they analyze and discuss scholarly work that has utilized these theories and frameworks. Building on a comparison of key messages, themes, and concerns, the authors highlight that to date, limited SFD scholarship has truly applied, extended, or challenged existing frameworks and conceptualizations. Motivated by this review, they posit several conceptual advancements, and offer directions for future research and theoretical development.     

中国耕地总量动态平衡的数量和质量分析

耕地作为土地的精华对我国农业和国民经济发展起着不可替代的基础性作用，为解决中国日益短缺的耕地资源和粮食安全问题，自1997年以来，我国实行了耕地总量动态平衡的土地管理政策，但耕地资源转化为非农建设用地的猛烈趋势仍缺乏有效的调控。基于耕地总量动态平衡的新视角和中国耕地资源变化态势和构成分析，提出了反映耕地总体产出能力的标准系数以及相对应的标准耕地面积，并进一步分析了我国耕地统计面积和标准面积的时空差异状况，从数量和质量两个方面重新考察了我国耕地总量动态平衡状况，并据此提出了实现中国耕地总量动态平衡的对策措施。
