Information-based management mode based on value network analysis for livestock enterprises

ABSTRACT

With the development of computer and IT technologies, enterprise management has gradually become information-based management. Moreover, due to poor technical competence and non-uniform management, most breeding enterprises show a lack of organisation in data collection and management. In addition, low levels of efficiency result in increasing production costs. This paper adopts ‘struts2’ in order to construct an information-based management system for standardised and normalised management within the process of production in beef cattle breeding enterprises. We present a radio-frequency identification system by studying multiple-tag anti-collision via a dynamic grouping ALOHA algorithm. This algorithm is based on the existing ALOHA algorithm and uses an improved packet dynamic of this algorithm, which is characterised by a high-throughput rate. This new algorithm can reach a throughput 42% higher than that of the general ALOHA algorithm. With a change in the number of tags, the system throughput is relatively stable.     

省际边界、方言边界和一价定律

逐步打破和消除市场分割,建立统一开放的市场体系,促进要素的合理流动及优化资源配置是我国经济转型时期面临的重要任务。本文使用1998-2010年123个地级市的月度价格数据,在一价定律框架下分析了27种服务品的短期价格偏差与省际边界、方言边界的关系。研究发现:(1)教育、医疗服务存在显著的省际边界效应,而其他服务的省际边界效应较弱;(2)教育服务还存在显著的方言边界效应,其中小学、初中、高中学习阶段的方言边界效应系数显著;(3)在考虑了样本异质性和样本选择偏误后,结果仍然稳健。上述研究结果反映出依附于行政边界的户籍制度通过影响教育、医疗受益性增加了劳动力省际转移的隐性成本,而地区间的方言差异通过影响随迁子女的教育进一步增加了劳动力跨区域流动的阻力。     

Environmental corporate social responsibility and the strategy to boost the airline’s image and customer loyalty intentions

This study aimed to uncover the role of an airline’s environmental corporate social responsibility in conjunction with building loyalty intentions of its customers while considering the mediating impact of its brand image, love and respect, as well as the moderating effect of environmental concerns. Our results from the structural analysis showed the salient role of environmental corporate social responsibility in determining loyalty intentions, and it was also a significant contributor to improving brand image, love, and respect that acted as significant mediators. Moreover, the results demonstrated a significant moderating effect of environmental concern on the brand respect and loyalty relationship.     

Cruise travel motivations and repeat cruising behaviour: impact of relationship investment

Passenger retention is undoubtedly one of the major challenges for cruise lines. Given that little is known about passengers’ post-purchase behaviour in the luxury cruise sector, this study addressed this omission by empirically verifying the imperative role of motivations, values, image, desire, and relationship investment in generating repeat cruising intentions. The proposed conceptual framework comprising these triggers was in general supported. In addition, its prediction ability for repurchase decision was sufficient. Specifically, our empirical findings demonstrated the adequacy of the higher order structure of cruise travel motivations that considerably increase hedonic and utilitarian values. Our results further identified the comparative importance of overall company image in determining intention. The mediating role of the study variables was also found. Lastly, the results of the metric-invariance model assessment revealed that relationship investment significantly moderated the value–image–desire linkages. Implications for tourism academics and cruise practitioners and future research directions are discussed.     

人民币汇率波动对中韩贸易影响的实证分析

以中美贸易摩擦为背景,应用不完全替代模型,基于中韩两国2011年第一季度到2019年第三季度的样本数据,采用Johanson协整检验和Granger因果检验,分析人民币汇率波动对中韩进出口额的影响.实证结果显示,中韩贸易存在理论上的J曲线效应.短期内,汇率对贸易收支具有恶化作用;长期中,整体存在正向作用.建议从国家层面进一步满足外汇衍生产品的市场需求;丰富外汇市场交易主体;积极推进中日韩自贸区的建立;加强货币互换等金融合作,持续推进人民币国际化进程.从企业层面来看,涉外企业应利用金融工具,规避汇率波动带来的风险;提高核心产品技术,增强国际市场竞争力;根据汇率波动的敏感差异,调整企业购销结构.     

基于"GM(1,1)模型"投资LNG项目财务评价研究

近年来,我国液化天然气(LNG)在全年能源使用消耗总量中占有的比值持续上升.由于其具有环境污染小、运输方便等优点,因此,在天然气市场占据了较大的市场份额.同时,由于其显著的经济效益,也受到了投资者的青眯,LNG项目成为能源企业的投资热点.在这种背景下,对LNG项目的动态经营成本进行评价分析,也成为投资者特别关注的方面.本文基于GM(1,1)模型,亦就是灰色系统,对LNG投资项目动态经营成本进行评价研究,为科学地投资LNG项目提供测算依据.     

Pursuing sustainable development through green entrepreneurship: An institutional perspective

Pursuing sustainable development through green entrepreneurship has been advocated, conceptualized, and empirically examined in the recent environmental management and entrepreneurship literature. However, green entrepreneurs are embedded in institutional environments that may discourage them from embracing sustainable development because of the “paradox of embedded agency.” How can a firm overcome the liability of such an agency issue and escape what has become known as a “green prison”? This study proposes that, because international venturing exposes firms to foreign institutions, it provides them with opportunities for institutional learning. Thus, we examine how international venturing influences green entrepreneurship which, in turn, impacts firm performance. Specifically, based on institutional theory, this study develops a firm-level green entrepreneurship framework with three dimensions: green initiatives (a firm's active adoption of green practices), received government green support (benefits that a firm gains from the government by adapting to governmental incentives, programs, and policies related to green practices), and green political influence (a firm's attempts to influence legislation that enacts laws, rules, and regulations related to green practices). The results obtained by analyzing 152 firms that engage in international venturing activities and 151 firms that do not show that international venturing is positively associated with green initiatives and government green support while these two factors further directly enhance firm performance and mediate the effects of international venturing on performance.

Evaluating user-generated content in social media: an effective approach to encourage greater pro-environmental behavior in tourism?

Appealing to tourists’ intrinsic interest for high-quality tourism environments, and thus encouraging them to act with a greater sense of personal responsibility toward the environment, could be critical to promoting sustainable tourism. Proliferating media channels makes the choice, style and delivery of pro-environmental messages a key issue for tourism marketers and management. Social media has become a recognized important channel for tourism information, with user-generated content (UGC) being more trusted than official channels, yet there is little knowledge about its potential role in activating pro-environmental norms. This study investigates that issue. Focusing on the conjoining aspects of personal and social norms for the first time, we propose a hypothetical model to explain the direct and indirect effects of pro-environmental UGC in activating tourists’ pro-environmental behavioral intentions. Working in a Chinese context, where social media plays an increasing role, the research, using a web-based sample (N = 1043), UGC-linked pro-environmental knowledge and awareness, was found to have a strong role in activating pro-environmental norms, creating a pro-environment online community, and increasing tourists’ level of engagement in pro-environmental social media activity. The study highlights the effectiveness of social media channels with UGC providing persuasive communications able to impact sustainable behaviors.
