Search results

The paper describes how slight changes to a free‐text retrieval system (DECO) enable two methods of searching (free‐text and hierarchical) to be offered in one system (VIEWDECO). Users are thus free to choose either method, without the need to switch between different databases. Apart from introducing menus, which are an integral part of a viewdata (hierarchical) system, the technique has also been used to incorporate help messages and other instructional aids. A third method of searching, the ‘Electronic Book’, is also described. Providing three methods of searching in one retrieval system caters for users with a much wider range of skills, and presents an opportunity for a gradual, self‐paced transition to free‐text searching. The technique involves relatively small changes, and should be applicable to many other inverted file, free‐text retrieval systems.

This study aims to explore the dependence structure among Chinese firms across the emerging 5G industry at different stages and to provide some strategic insights for market participants.

This study adopt macroeconomic fundamentals and the log-returns of 45 listed firms in the Chinese 5G industry to construct the weighted adjacency matrix by measuring the correlation parameters and then use the triangulated maximally filtered graph (TMFG) algorithm to construct the dependence network. It analyses the topological structure of the constructed networks to obtain the dependence characteristics for each firm in the whole industrial supply chain at different levels.

The empirical results provide a comprehensive and concise snapshot of the industrial structure, across the whole 5G industry at different levels, rather than just a “one-to-one” pattern. Specifically, the dependence characteristics of different firms are heterogeneous, and most firms are highly connected with partners in the whole industrial supply chain, whereas a few firms that are weakly connected. Those closely connected firms are usually in the midstream. In addition, compared with firms at different levels, downstream firms usually have closer dependencies and stronger influence capabilities.

Regulators not only should promote stability development for those firms most intensely connected with whole industry chain but also protect those firms with weak link in the whole industry chain. Investors should better understand the embedded ties among different firms to obtain effective market information and can select multiple firms with fewer connections as backup to conduct joint investment for risk mitigation. Mangers should give priority to the central players/firms in the whole industrial supply chain and establish the alliances with closely connected firms.

This study contributes to both the information system and operation management literature by constructing a new network method, Copula-TMFG, to capture the dependence structure among Chinese firms in 5G industry, empirically providing some strategic insights for 5G industry stakeholders, such as regulators, investors and managers.

This study assesses the factors influencing customers’ intention to adopt e-banking in the context of the technology acceptance model and the moderation role of cybercrime.

The variables in the study are measured using a five-point Likert scale with measures adopted from existing literature. The independent variables are perceived ease of use, perceived usefulness and security and privacy. These are postulated to be moderated by the perceived risk of cybercrime and to influence e-banking adoption intentions. A quantitative approach is used. Primary data are collected from a sample of 209 randomly selected bank customers. The study uses a two-step (measurement model and structural model) approach to data analysis.

The key findings in this study are that perceived risk of cybercrime strengthens the positive relationship between perceived ease of use and e-banking adoption intentions but dampens or weakens the positive relationship between perceived usefulness and customers’ e-banking adoption intentions. The study makes several recommendations to inform scholarship, policy and practice.

Unlike existing literature, the study makes a unique contribution by including perceived risk of cybercrime as a moderating variable of theoretical significance in the relationship between adoption of e-banking and its determinants.

The chapter is devoted to considering the aspects of the COVID-19 pandemic influence on the global and Russian electronics industry. The work aims to examine the impact of the COVID-19 pandemic on the electronic industry in the world and Russia from various angles. As a result of the study, the main features of the global electronic industry are highlighted, including leadership of Western European countries, Japan and the United States in the segment of high price electronics; the leadership of the new industrial countries in a lower price segment; active development of microelectronics as an electronics industry segment and its colossal role in the economy of modern countries; the trend towards acquisitions of small companies by large corporations and other industry. Key problems of the Russian electronics are identified, including a small fraction of the global electronics dependence of Russian industry on imported electronic components, a huge backlog of electronic industry of Russia in comparison of world leaders and the newly industrialized countries, technological backwardness of many enterprises of electronic industry, the low level of qualification as a whole industry. The novelty of the research is highlighting the impact of the COVID-19 pandemic on the electronics industry. The study highlights both negative consequences (decline in production of many electronic enterprises, disruption of supply chains, insufficient financing of the industry) and positive aspects (active growth of the segment of household appliances and electronics), as well as an impetus to the development of new directions of world electronics (radio-photonics, optoelectronic and quantum technologies, artificial intelligence, laser technology).

The purpose of this paper is to evaluate the innovation perception, in its different aspects, of the Spanish people. To this end, several ordered logit models have been developed to determine the extent to which socio-demographic characteristics and other aspects of innovation affect the perception of innovation.

This paper analyses the perception of individuals about innovation in Spain and the related factors. It uses 2015 and 2018 data on individuals from Spanish surveys. The data include various measures of innovation perception, age, gender, educational level and other socio-economic variables.

The results indicate that people have a better perception of innovation if they are being trained in innovation or have good information and communication technologies skills. Among the main results, there is a gender gap in the perception of innovation, as well as differences in terms of digital skills.

To the best of the authors’ knowledge, it is the first time of this kind of analysis in this country. The results are linked to the literature, but should nevertheless be taken into account, which is why some policy recommendations are presented below.

THE Trident 2E is fitted with a further development of the Rolls‐Royce Spey RB.163–25 turbofan engine, designated the Spey 25 Mk. 512–5W. This engine develops a nominal 12,000 lb. take‐off thrust for a dry weight of 2,590 lb.

The interior lighting in the new B.O.A.C. hangars at London Airport is automatically controlled by a comprehensive photoelectric system installed by Rashleigh Phipps and Co. Ltd., Esmond Court, Thackeray Court, Thackeray Street, London, W.8. This system ensures that the interiors of the hangars are maintained at a uniform level of illumination both by day and by night, and during fogs. At the same time the photoelectric control, by switching off the interior lighting as soon as the daylight renders it superfluous, obviates any wastage of electricity.

It will be recalled that the last monograph treated the significance of the collective agreement in society. If solely a function in society, (though having a legal basis), were to be attributed to the collective agreement, this would mean that no rights or obligations whatsoever would be created between the parties to it. This is not so in practice. It is of course a fact that no legally enforceable rights and obligations normally accrue, and as already indicated, those are moral ones and are only enforceable in honour, i.e. a gentleman's agreement. Nevertheless, this does not necessarily mean that the collective agreement has no juridical significance. Even agreements which are binding in honour only, as for example the kind of agreement found in Balfour v. Balfour, have a known juridical nature. Furthermore, though the collective agreement is only binding in honour, its incorporation into the individual contract of employment makes its terms legally enforceable even though recourse to the courts is seldom had. As a source of rights and obligations of considerable importance the collective agreement must therefore have some juridical significance and cannot remain entirely in the realms of society.
