人工智能时代情报学发展走向之辨——对本体论、感知论、方法论、服务论的再思考     

曹文振  赖纪瑶  王延飞 《情报学报》2020,39(5):557-564

人工智能相关技术的迅猛发展和逐步普及,使得情报学难以避免人工智能的融合趋势,无论这种融合是主动为之或是被动选择。然而学界对人工智能时代情报学学科的发展走向并未予以充分探讨,大部分研究均将焦点置于大数据与下一代互联网环境中进行论述。本研究将人工智能时代情报学学科走向解构为"本体论""感知论""方法论""服务论"四个论题,对每个论题借由理论面向与实践面向的二分法展开阐释,并从整体视角上提出应在人工智能洪流中找准情报学定位,不能忽视"人"在情报学中的价值以及重视跨学科融合、跨领域应用的发展趋势。  相似文献   

集装化危险品物流作业风险因素识别与评价     

何景师  张智勇 《上海海事大学学报》2020,41(4):62-69

为识别与评价集装化危险品物流作业的风险因素，通过鱼骨图分析法构建风险因素评价指标体系。以风险发生的概率和后果为决策变量建立基于熵权 层次分析法（analytic hierarchy process, AHP）约束的数据包络分析(data envelopment analysis, DEA)法的风险评价模型。利用熵权 AHP解决传统DEA法的权重无限性问题，利用DEA法求解风险极大、极小值并对风险因素进行评价与排序。研究发现，人员风险、包装风险达到风险极大值，集装箱风险达到风险极小值。研究得到各风险因素决策单元的风险降低比例，并根据风险因素的特点提出集装化危险品物流作业风险管理的建议。结果表明了该评价模型的适用性和评价方法的科学性。  相似文献   

From shanzhai chic to Gangnam style: seven practices of cultural-economic mediation in China and Korea     

Tommy Tse  Victor Shin  Ling Tung Tsang 《Journal of Cultural Economy》2020,13(5):511-530

ABSTRACT

This paper examines the social construction of ‘fashionability’ – namely, what is ‘desirable’ and ‘fashionable’ – with reference to the concept ‘cultural mediators’ that foregrounds agency, negotiation and the contested practices of market actors in cultural production. It zeroes in on the cultural mediators’ attitudes and positions in the two markets by drawing on 25 in-depth interviews with industry veterans. It shows that the mediators in South Korea and China increasingly occupy hybrid occupational roles and social positions across industries and sectors yet achieve limited success in countering the status quo of Western fashion through mediation. The analysis contributes to the literature with a categorisation of seven mediation practices that shape the valuation of fashion products (i.e. ‘fashionability’) in two ways. Empirically, this categorisation illuminates how cultural mediators make reference habitually to the broader social and cultural contexts to co-construct cultural-aesthetic objects. Theoretically, it advances a cultural-economic approach to the understanding of cultural mediation and challenges the reductionist viewpoint of actor–network theory through the notion of a matrix of cultural-economic agency.  相似文献   

Motivation profiles of urban preservice teachers: Relations to socialization,initial career perceptions,and demographics     

《Contemporary educational psychology》2021

Given the perennial challenge of attracting and retaining high-quality teachers, especially in large cities, there is a need to understand why preservice teachers in urban districts choose a teaching career, their perceptions of the profession, and how these relate to their initial career commitments and aspirations. Using latent profile analysis, we examined patterns of motivational perceptions with variables from the Factors Influencing Teacher Choice model alongside perceived task effort cost, opportunity cost, and emotional cost of teaching within a diverse sample of 630 preservice teachers. We identified four distinct profiles that differentially related to theorized antecedents (prior teaching and learning experiences, social encouragement, fallback career) and outcomes (satisfaction, planned persistence, planned professional development, leadership aspirations). Race, gender and certification-level were distributed in unique patterns across profiles. Results provide a holistic perspective of preservice teacher motivations and indicate that perceived costs in relation to FIT Choice variables were a defining characteristic of motivational patterns.  相似文献

Leader prototypicality in sport: The implicit leadership theories of women and men entering sport management careers     

《Sport Management Review》2020,23(4):640-656

Implicit leadership theories (ILTs) matter because they are used as the benchmark against which people determine who is a leader and who is not. This assessment informs their behavioral responses. People are thought to have a superordinate-level ILT representing their prototypical mental model of leadership and a series of basic-level ILTs. Each of these represents how people conceptualize leadership in particular domains (e.g., sport, politics, and popular culture). In this study, the authors generate the structures of basic-level sport management ILTs for women and men who are about to enter this industry. These form the baseline from which socialization to work, organizational cultures, and the sport management industry begins. The ILTs of women entering sport management careers have a 35-item, 6-factor structure (Sensitivity, Knowledgeable, Physical Attractiveness, Inspirational, Dedication, and Focused), whereas men entering the industry have a 32-item, 7-factor structure (Sensitivity, Dedication, Physical Attractiveness, Focused, Creativity, Inspirational, Courageous). The resulting sport management ILT profiles differ from superordinate ones by emphasizing physical and vitality attributes, incorporating emotional elements, and by eschewing antiprototypical elements. The paper ends with a discussion of the implications for leadership research in sport management.  相似文献   

When digitalized customers meet digitalized services: A digitalized social cognitive perspective of omnichannel service usage     

《International Journal of Information Management》2020

With the prevalence of digital technologies, various services have grown digitalized. Specific to the marketing section, multichannel has been gradually replaced by omnichannel, which aims to integrate all the physical and digital channels tightly. Although omnichannel has received considerable attention, there is still a dearth of research that theorizes the multi-faceted impacts of digitalization on omnichannel. This study thus extends social cognitive theory (SCT) to the digitalized context and contextualizes the digitalized customer and digitalized environment as mobile identity and channel integration quality, respectively. Moreover, based on the self-regulation process of human agency, we incorporate omnichannel self-efficacy, satisfaction, and habit as the agentic factors to interpret a customer’s conscious (ability and expectancy beliefs) and unconscious (automatic behavioral tendency) decision-making under the omnichannel setting. Through an online survey of 401 omnichannel customers, we find support for all the proposed hypotheses. Implications and limitations of this study are further discussed.  相似文献

主题内容频数相关分析与历代书法理论演替关系研究     

张捷  饶薇  王小伦 《情报科学》2006,24(12):1822-1827

针对古代文献引用方式的特殊性和无法运用常规引文分析及关键词分析方法进行研究的现状，本文以主题内容为检索单元以朝代为时间单元进行频数统计研究，将贯穿中国历代传统书法理论（书论）中的大量自然意象描述主题内容分为21类，并以此为指标进行分朝代统计，进而采用线性回归方法计算不同朝代书论之间的相关性，并以此作为各朝书论之间的传承关系。论文同时利用文史考证材料对所揭示的传承现象进行了分析、验证和阐释。  相似文献
