Running Scaling Dimensions in Holographic Renormalization Group Flows

Holographic renormalization group flows can be interpreted in terms of effective field theory. Based on such an interpretation, a formula for the running scaling dimensions of gauge-invariant operators along such flows is proposed. The formula is checked for some simple examples from the AdS/CFT correspondence, but can be applied also in non-AdS/non-CFT cases.Comment: 14 pages, 2 figure

Industry 4.0: a bibliometric review of its managerial intellectual structure and potential evolution in the service industries

The “industry 4.0” phenomenon is expected to influence almost every aspect of business value chains, and hence it has been increasingly analyzed by management scholars. However, the overarching intellectual structure emerging from this new stream of literature has not yet been synthesized in a framework nor critically discussed. Furthermore, despite being part of the rhetoric in several recent industrial governmental plans, industry 4.0 in service sectors has not been systematically reviewed to date. By leveraging a systematic quantitative literature review, a data-driven approach and a quantitative methodology—embedding both bibliographic coupling and network analysis techniques—this study provides a clear visualization of the emerging intellectual structure of industry 4.0 in management studies. We also develop a framework based on the most recurrent themes emerging from the results of bibliometric and network analyses—the latter could be used by management scholars to understand studies surrounding industry 4.0. As service businesses can create and capture value generated through the 4th Industrial Revolution as well as manufacturing firms, we suggest that scholarly attention should also be directed toward the service industries and provide a research agenda

How do you feel when you see a list of prices? the interplay among price dispersion, perceived risk and initial trust in Chinese C2C market

The issues of trust fraud, product genuineness and price dispersion jointly make Chinese C2C buyers difficult to identify trustworthy sellers with a low price. Little is known about the generation of initial trust when buyers search products and receive lists of widely ranged prices. This study proposes a theoretical model to explain how price dispersion interacts with other factors in C2C purchase, such as initial trust, perceived risk, perceived value and purchase intention. Product type is considered as a moderator. 261 students were invited in a survey-based experiment. The results from PLS analysis show that price dispersion negatively affects perceived value, whilst, positively affects perceived risk, which further influences perceived value negatively. Price dispersion also negatively influences initial trust through perceived risk. Moreover, the negative effects of price dispersion are stronger when buyers purchase high-touch products

Do industry 4.0 technologies matter when companies backshore manufacturing activities? An explorative study comparing Europe and the US

The objective of this chapter is to analyze the impact (if any) of Industry 4.0 enabling technology on firms’ decision to relocate to the home country their offshored production activities. In particular, the chapter analyzes whether Industry 4.0 technologies may represent a driver/motivation or an enabling factor for companies which are evaluating such a strategic alternative. In order to reach such an objective, a two-step explorative methodology has been applied. After implementing a structured literature review, empirical evidence of backshoring decisions implemented by both European and US companies has been analyzed. Collected findings show that the majority of sampled articles conceptualize Industry 4.0 technologies as a driver. At the same time, empirical findings show some interesting differences between European and US companies adopting backshoring decisions based on/enabled by Industry 4.0 technologies. Finally, competences (related to both the manufacturing activities as a whole and the Industry 4.0 technologies) emerge as one of the most critical issue for investigated companies
