林业职业技术培训研究进展与展望

从文献研究规模、研究主题以及研究机构三个方面对林业培训文献进行梳理,并从培训现状、尚存在的问题、培训研究方法以及培训对策对文献进行分析。结果发现:尽管林业培训越来越受到林业局以及林户的重视,但依旧存在培训内容不够全面、培训效果评估体系不够健全等问题。从政府和林业局、参与培训的林户以及该领域的研究学者三个方面提出了相应的建议。     

Free add-on services and perceived value in competitive environments: Evidence from online hotel reviews

This study investigates how free add-on services affect customers’ perceived value in horizontal and vertical competition. We collected 349,879 reviews about over 3000 hotels in 25 U.S. cities from TripAdvisor. Using three balanced data sets generated by coarsened exact matching, the ordered logistic regressions show that free hotel add-on services (including free breakfast, parking, and WiFi) positively affect consumers’ perceived value. However, increased horizontal and vertical competition differentially weakens the positive effects of free add-on services. We not only observe a negative moderating effect of horizontal competition, but also identify three patterns of the marginal effects of these three add-ons in horizontal competition. The moderating effect of vertical competition exists from the higher-grade hotel segment to a lower-grade hotel, but such an effect is insignificant from the lower-grade hotel segment to a higher-grade hotel. Therefore, hotel managers should consider diverse external competitive environments and design appropriate differentiated service strategies.     

家庭旅游研究进展——基于2000-2019年英文文献的综述

家庭旅游是全球旅游业最重要的细分市场。近年来,我国家庭旅游市场的规模和发展潜力受到业界的广泛关注,但相对于我国家庭旅游市场的发展实践,国内学术界对这一细分市场的研究明显不足。文章对2000-2019年发表在英文期刊的136篇家庭旅游文献进行了系统梳理,研究发现国际学术界日益关注家庭旅游,文献数量不断增长,但研究地域主要集中在北美和欧洲等发达国家和地区。研究方法以定量研究为主,研究主题、数据获取方法呈现出多元化的趋势,研究对象聚焦儿童参与的核心家庭旅游活动。研究主要以家庭消费的计量模型、家庭角色和家庭资源/权力理论、体验理论和家庭功能理论等为基础,可归纳为消费、决策、体验和功能等4个研究视角。基于英文研究的局限,并结合中国的文化、家庭、市场和社会特征,文章提出了中国家庭旅游研究应该重点关注的4个方向:(1)中国文化价值观及其影响;(2)中国家庭角色和结构特征;(3)家庭旅游市场的供给研究;(4)积极老龄化(active aging)和社会功能。     

A systematic review of AI technology-based service encounters: Implications for hospitality and tourism operations

The hospitality and tourism industry faces serious challenges during public health emergencies such as COVID-19. Managers are concerned not only about how to maintain business and provide humanized services but also about social distancing. This study presented artificial intelligence (AI) technology-based service encounters as a possible solution and examined the antecedents and consequences of the encounter triad including customers, employees, and AI. Based on a systematic literature review, the study identified 4 modes of AI technology-based service encounters: AI-supplemented, AI-generated, AI-mediated, and AI-facilitated encounters. In addition, the study developed an integrated model to specify the factors that influence AI technology-infused service encounters in general and the customer service outcomes that result from the encounters. The findings contribute to service management and AI application theoretically and practically.     

国外生态修复研究进展评述

研究目的:系统总结国外生态修复研究的重点进展和主流共识,为把握未来生态修复研究的前沿态势提供参考。研究方法:文献研究法。研究结果:按照生态修复的"目标导向—技术方法—成效评价"的框架进行梳理,现有研究在生态修复的对象及尺度、生态学及社会经济文化目标、各类型生态系统及要素的修复技术方法、成效评价维度及指标等方面取得了一定的研究进展,但总体而言,目前生态修复研究存在理论—实践—政策之间知识转移欠缺、生态学与社会经济学科交叉研究不足、全球气候变化背景下的研究缺乏等问题。研究结论:理论—实践—政策耦合研究、生态学—社会经济学科交叉研究、气候变化—生态修复联动研究等可能是未来生态修复领域的重点研究方向。     

2019年土地科学研究重点进展评述及2020年展望——土地管理分报告

研究目的：归纳分析2019年国内外土地管理领域研究进展，展望研究趋势。研究方法：文献研究法。研究结果：2019年，国内土地管理问题研究涉及基本理论、制度变迁及土地管理体制、制度、政策和法律等方面，关注实践中的新情况、新问题；国外土地管理研究偏向关注土地问题尖锐的发展中国家和第三世界国家；土地管理体制、制度、法律、权籍与利用问题是国内外共性研究内容。研究结论：2019年土地管理研究紧扣理论与实践问题，在探索土地管理体制与实施机制方面取得了进展，但仍需加强方法创新与土地管理科学规律凝练；2020年将重点关注土地治理体系改善、土地计划管理方式改革、农村土地制度改革、城乡土地统一市场、国家重大区域战略实施中的土地管理问题、自然资源资产产权制度改革、自然资源统一确权登记、耕地保护转型、自然保护地管理、国土空间规划管理、土地市场管理与产业用地政策创新等议题。     

THE ECONOMIC AND BEHAVIORAL CONSEQUENCES OF ONLINE USER REVIEWS

Online user reviews have become an increasingly relevant informational tool during product search and adoption. Recent surveys have shown that consumers trust and rely on online reviews more than they do on website recommendations and experts opinions. As a new way of driving consumer purchasing intentions, online user reviews have therefore come under scrutiny by researchers. The objective of this paper is to offer an overview of the literature regarding the impact of online user reviews on economic indicators (e.g., sales, marketing strategies) and on consumer behavior. Furthermore, following the growing interest of academics and professionals alike on the topic, the present work provides an exploratory analysis of the consequences of online reviews on individual rating behavior – empirical regularities showed that online rating distributions tend to be concentrated on extreme values, possibly because of rating biases. As consumers and firms incorporate the heuristic cues from such distributions into their decision-making processes, biased ratings might lead to suboptimal choices. This overview presents established results (e.g., the impact of volume on product sales) and insights as issues for future research.     

UNIVERSAL PRESCHOOL PROGRAMS AND LONG-TERM CHILD OUTCOMES: A SYSTEMATIC REVIEW

What are the long-term effects of universal preschool programs on child outcomes? We review 26 studies using natural experiments to estimate the effects of universal preschool programs for children aged 0–6 years on child outcomes measured from third grade to adulthood. Studies comparing universal preschool with a mix of parental, family, and private modes of care show mixed effects on test scores and on measures related to health, well-being, and behavior. All estimates for outcomes related to adequate primary and secondary school progression, years of schooling, highest degree completed, employment, and earnings indicate beneficial average effects of universal preschool programs. Three of the included studies calculate benefits-to-costs ratios and find ratios clearly above one. Universal preschool tends to be more beneficial for children with low socioeconomic status and there are not consistently different effects for boys or girls. Only three studies compare two alternative types of universal preschool programs in terms of long-term outcomes.     

SYSTEMATIC LITERATURE REVIEW OF TOURISM GROWTH NEXUS: AN OVERVIEW OF THE LITERATURE AND A CONTENT ANALYSIS OF 100 MOST INFLUENTIAL PAPERS

This study performs the first citation-based systematic literature review of the tourism-growth nexus. The citation analysis provides a bird's eye view of this literature, which, in turn, identifies the sources of knowledge in terms of most influential journals, authors, and articles. A detailed content analysis of 100 most influential papers has been generated on the nature of the study, variables used, country of analysis, type of analysis, the methodology, and the direction of causality. In total, 284 papers were found relevant in the Scopus database using a comprehensive list of keywords. The citation analysis reveals that Tourism Management is the leading journal with a total of 2527 citation counts, whereas Tourism Economics is the leading journal with a total of 41 publications on this topic. Juan Gabriel Brida is the most prolific author, whereas Lee and Chang (2008) is recognized as the most influential paper. The content analysis reveals that 58% have applied time series, and 38% have used panel data analysis. Tourism causing growth is the leading result of both time-series and panel studies. International tourism receipts/earnings/expenditure and the number of international tourist arrivals are the most widely used variables to measure tourism.     

Partial least squares structural equation modeling in HRM research

Abstract

Partial least squares structural equation modeling (PLS-SEM) has become a key multivariate analysis technique that human resource management (HRM) researchers frequently use. While most disciplines undertake regular critical reflections on the use of important methods to ensure rigorous research and publication practices, the use of PLS-SEM in HRM has not been analyzed so far. To address this gap in HRM literature, this paper presents a critical review of PLS-SEM use in 77 HRM studies published over a 30-year period in leading journals. By contrasting the review results with state-of-the-art guidelines for use of the method, we identify several areas that offer room of improvement when applying PLS-SEM in HRM studies. Our findings offer important guidance for future use of the PLS-SEM method in HRM and related fields.
