Tourism as complex interdisciplinary research object

Tourism is currently a complex and globalised phenomenon with demonstrated socio-economic importance. While tourism is a socially recognised phenomenon, its status as scientific object within an academic field seems to be still in question. We ask the following questions: What is the order of construction of the field of knowledge constituted around tourism? Is it a paradigmatic order or an epistemic order? In what ways do the scientific object’s specificities constitute an important element of understanding of a new episteme? How do different definitions of tourism allow for a reconstruction of the field? This article seeks to summarise the current debate in the light of broader reconstructions of scientific discourse and reflect from an interdisciplinary epistemological perspective.     

铁路桥连续刚构边跨现浇段的吊架设计及受力检算

采用挂篮施工的连续刚构边跨现浇段的支架形式多种多样,其设计目的是施工简便、安全牢固、确保质量及节约成本。在遂渝二线铁路薛家坝涪江左线特大桥连续刚构梁边跨现浇段施工时采用型钢吊架支撑,吊架分别利用原施工悬浇节段的挂篮及在墩顶预埋工字钢作支承点。吊架施工现浇段不仅结构简单、施工方便,而且在安全、质量及效益方面均取得了很好的效果。文章对型钢吊架的设计、施工方法进行了详细介绍,并对吊架进行了受力分析及验算,验证了方案的可行性,为以后同类桥型的施工提供参考。

Eighteenth-Century Evolutionary Thought and its Relevance in the Age of Legislation

This essay revisits the evolutionist writingsof the eighteenth century to clarify their key ideas concerninglegal and social evolution and to assess their relevance in thepresent era of pervasive legislation. The discovery of the principleof the accumulation of design is traced to these writings andthe continuity of twentieth century spontaneous-order theoryand new institutional economics with this tradition is noted.While highlighting the contributions of other institutional theoriststo the elucidation of the role of purposive action in legal evolution,the author argues that input designing does not alter the fundamentalnature of legal emergence as postulated by the eighteenth centuryscholars. The essay supports the ideal of legal generality, freespeech, property and contractual freedom as normative implicationsof the evolutionary viewpoint.     

Technological Complexity and Country-of-Origin Effects on Binational Product Evaluation: Investigation in an Emerging Market

ABSTRACT

Research into the impact of the country of origin (COO) dimensions on product perceived quality in emerging markets is limited and does not distinguish between technologically complex/simple products. This paper investigates country-of-design (COD) and country-of-manufacture (COM) effects through their two subconstructs (global country image and the perceived capacity of the country to design/manufacture products), on the perceived quality of four products varying in their level of technological complexity. Findings indicate that consumers are more sensitive to COM than COD for complex and for simple products, and that COD only affects product quality for products carrying symbolic meaning. The findings have marketing implications for binational products entering emerging markets.     

Towards multi-system sociotechnical transitions: why simulate

A number of research frameworks have been developed for studying sociotechnical transitions. These are complex phenomena, particularly those involving multi-system interactions. Given these characteristics, the paper discusses the challenges in studying transitions solely through inductive inference methods. It argues that transition research has reached a point where taking the next step should include modelling and simulation as part of the standard methodological exploratory toolkit for studying the intensity, nature and timing of system interaction that lead to transitions and for producing timely and robust policy recommendations.     

eWOM across channels: comparing the impact of self-enhancement,positivity bias and vengeance on Facebook and Twitter

Abstract

When sharing personal details, versus talking about others, consumers tend to accentuate the positive experiences they have with brands in order to self-enhance amongst friends. Consumers also take vengeance on brands in public venues. Turning to social network sites (SNSs), it is unclear which is dominant. Here historical Facebook and Twitter eWOM (n = 47,907) is analyzed for a static group of 783 active US consumers. Self-enhancement is found on both SNSs. The majority of eWOM is positive Vengeance was rare, occurring only in 10.3% of all eWOM. eWOM appears to mirror a consumer's non-eWOM sentiment valence across SNSs. In this cross-platform comparison we suggest that SNS affordances alter eWOM creation Facebook has privacy expectations and limits direct brand interactions. Twitter is a public platform with less privacy expectations and a larger customer service component. Here eWOM is more prevalent on Twitter but contrary to our expectations is more positive.
