Walloon & Flemish videotex trials

This article focuses on the problems surrounding ‘compunication’, ie the growing imbrication between electronic computers and telecommunications. (The corresponding French term is télématique). More precisely, the specific problems of videotex systems thrown up by different experiments in Belgium are examined. The CCITT of the ITU uses the term videotex as the generic name referring to all systems that make it possible to gain information through telecommunication networks (Hertzian waves, cable TV distribution networks or telephone lines). Requested information appears on a TV screen (at home, in a place of work or in a public place).     

Videotex for news and business data: Comparison of user response to two information retrieval applications

An empirical comparison of user response to two information services offered by a prototype videotex system indicated that the business (ie farm market data) service was rated as more efficient and that users browsed more in that service than in the consumer (ie news) service. Further, both efficiency ratings and amount of browsing were more strongly correlated with amount of service use, ratings of service value and ratings of dependence upon the service for the business service than for the consumer service. Browsing thus seems to be a utitarian surveillance behaviour rather than a communication play behaviour in this setting.     

住房抵押贷款提前还贷风险管理研究

从现代金融和风险管理角度看,住房抵押贷款提前还贷对商业银行是一种期权性风险,对其收取违约金并非国际惯例,也并不是有效的风险补偿方式。商业银行应适应市场竞争需要,接受风险转嫁并提供风险管理服务,运用风险定价技术在按揭交易价格中对提前还贷风险进行补偿。对于已承担的风险,商业银行应构建抵押贷款提前还贷的数据库,通过表内对;中和市场对冲,推出多样化的住房抵押贷款方式,积极推进住房抵押贷款证券化．从而最终增强银行的盈利来源和核心竞争力。     

Factors influencing the user acceptance of digital home services

Digital home services provide multimedia entertainment, communication, and healthcare services to the public in order to make their lives more convenient. Many articles predict that the digital home service market will be huge and that many will take advantage of this situation. The purpose of this paper is to identify the future market for digital home services in South Korea by exploring the existing critical information and literature. This study proposes a conceptual model for assessing the adoption of digital home services, for which survey data from 600 heads of households in Korea were collected and used to test the proposed model. This paper also examines customer characteristics and their relationship with the acceptance of digital home services. First, the findings indicate that infra-service is mainly determined by age, region, job, family type, house type, and attitude towards adoption of new products. Second, home entertainment service is also significantly affected by gender, age, region, family type, family member, house type, and attitude towards adoption of new products. Third, home healthcare service was positively affected by gender, region, job, and usage period of high-speed internet. This study may provide companies with valuable guidelines for the implementation of digital home services.     

What will be the possible barriers to consumers’ adoption of smart home services?

Recently, smart home services have come to the forefront as part of the growing market for the “Internet of Things.” Since these smart home services were introduced, they have been expected to grow rapidly. However, contrary to optimistic expectations for future market growth, the smart home market has appeared to hit a roadblock and remains at an early market stage. This study attempts to identify the possible barriers that consumers perceive when they are introduced to smart home services. Based on the resistance theory and perceived risk model, we investigate the relationship between perceived risk and resistance to smart home services, using technological uncertainty and service intangibility as the antecedents of perceived risk. Dividing perceived risk into four dimensions—performance risk, financial risk, privacy risk, and psychological risk—the empirical results show that these four risk types are affected by technology uncertainty and service intangibility, and the perceived risks, except for financial risk, have positive effects on the resistance to smart home services. When the survey respondents are divided into two types, postponers and rejecters, the result of postponers is similar with that of total sample, except that privacy risk is unimportant to postponers, and the result of rejecter cannot satisfy the recommended model fit.     

The videotex marketplace: A theory of evolution

Prospects for videotex in general and for business videotex applications in particular, are still highly controversial and speculative. There is growing agreement, however, that the future of videotex as a mass medium may hinge on its initial acceptance as a business tool. The authors present their views on the factors that will influence the use of videotex in business; how it may evolve as a business tool; and how its early impact in the business environment may eventually be the cause of its acceptance as a mass consumer medium.     

Local number portability and local loop competition. Critical issues

Local telephone number portability (LNP), the ability of a telephone subscriber to change local exchange carriers, location or type of service without changing telephone numbers, is an essential feature of a competitive local loop market. This article describes these three types of portability and then examines the implications for local loop competition of specific LNP issues: implementation techniques; E-911 emergency services delivery; neutrality of subscriber database and number administration; infrastructure cost allocation and cost recovery. Evolution of number portability policy in the US, including jurisdictional complications, is reviewed.

Computing Technology for the Home: Product Strategies for the Next Generation

Recent developments in the personal and home computer marketplace have raised questions about the effectiveness of current product strategies. In this article, Alladi Venkatesh and Nicholas Vitalari focus on the home computer market which continues to evolve in different ways. Specifically, they identify five technologically oriented product strategies, the electronic game technology strategy, the children's educational focus strategy, the office technology transfer strategy, the consumer electronic interchange strategy, and the home information systems strategy. The authors feel that the home information systems strategy may have the best long-run potential for success because it comes closest to meeting the needs of the changing household.     

Competitive relationships between traditional and contemporary telecommunication services in Taiwan

This study sets out to examine the competitive relationships that exist within the telecommunications market using the niche theory on the personal gratifications and system gratifications dimensions. The findings from the analysis of 363 survey responses indicate that traditional and contemporary telecommunication services offer different specializations to satisfy their consumers. Overall, mobile telecommunication services partially replace wired services, on personal gratifications dimensions in particular. The system gratifications dimensions of the wired telecommunication services facilitate the existence of wired services. New telecommunication services (3G and VoIP) partially replace old telecommunication services (home landline and 2G) in providing greater satisfaction in entertainment. The results also demonstrate that VoIP does not impose competitive displacement effects on home landline, 2G, and 3G services. Limitation and suggestions are discussed.     

Servicing the media: freelancing, teleworking and 'enterprising' careers

This article examines the working lives of people offering services to the media on a freelance basis. Almost all work from home using information and communication technologies but isolation in the home is not the norm as most maintain extensive personal networks in the industry. Nevertheless, popular imagery of the 'electronic cottage' and the 'virtual organisation only superficially capture their experiences. Insecurity and weakness in the market are suggested by histories of redundancy and dependence on single client organisations including former employers.     

The Green thumb videotex experiment: Evaluation and policy implications

The authors report on an evaluation of Green Thumb, a videotex experiment carried out by the Cooperative Extension Service and the US Department of Agriculture. Green Thumb provided marketing, weather and other information to 200 farm families in Kentucky. The experiment was a successful demonstration of the concept of providing farming information via new communication technologies, but the specific configuration and organizational arrangements will have to be improved in future systems. Policy issues concerning the role of USDA in future agricultural systems are discussed.     

Are more resources always better for growth? Resource stickiness in market and product expansion

We examine how managerial growth logics combine with financial and human resource slack to influence the short‐term revenue growth of a sample of 112 manufacturing firms drawn from a unique database provided by the Ewing Marion Kauffman Foundation. Our results provide evidence that firms pursuing product expansion logics generally grow more slowly than firms that are not expanding their product base, but that financial slack positively moderates this relationship. We also find that human resource slack enhances short‐term market expansion, but slows down short‐term product expansion. We discuss the implications of these results for resource‐based views of growth. Copyright © 2004 John Wiley & Sons, Ltd.     

Product Change Intensity, Product Advantage, and Market Performance: An Empirical Investigation of the PC Industry

Product change decisions, such as the frequency of new product introductions, can impact product performance characteristics, sales, and market share of several generations of products and, therefore, a firm's long‐term survival and growth. The purpose of this study was to explore the impact of a firm's product change frequency, also referred to as product change intensity. A conceptual model linking a firm's product change intensity to its product advantage—and, in turn, to its market performance—with strategic product change orientation and technology competence as moderating effects, was used as a foundation for the study's hypotheses. These were tested using hierarchical and linear regressions, based on survey data collected from 55 U.S. companies in the personal computer (PC) industry. The analysis confirmed that a PC firm's product rate of change is positively associated with its product advantage and that its product advantage, in turn, is positively associated with its market share and growth performance. However, the hypothesized moderating effects were not confirmed. Rather, a firm's product change orientation and its level of technology competence are more likely to have a direct impact on product advantage. The implications of these findings are that, in general, firms that release new products frequently will have them viewed more favorably by the market than products with lower change intensities. Also, firms with higher levels of competence in the product technology domain tend to create products with greater market attraction. Finally, more radical changes to PC product architectures may pay off better than relatively minor changes. These results may not apply to other industries due to the specific design of personal computers and the nature of this fast‐paced market. Neither do the findings necessarily apply to all firms regardless of those firms' specific product and market strategies. More research is necessary to understand how a firm's adopted strategy, and the industry in which it operates, affect the relationships demonstrated in this study.     

Market power,regulatory convergence,and the role of data in digital markets

The increased economic importance of digital services has profoundly changed the power structure in telecommunications and media markets. Although these services sometimes directly compete with traditional telecommunications services, the regulatory obligations for both players differ significantly. This article discusses three important areas deemed relevant in order to define a coherent regulatory framework and to account for the specific peculiarities of digital markets: First, challenges associated with assessing market power in digital markets. Second, challenges in harmonizing different regulatory obligations for digital services, and third, the vital role of data and data protection in the context of data-driven business models.     

The determinants of innovation in green supply chains: evidence from an Italian sectoral study

Innovation processes are increasingly spreading through the unbounded universe of European small and medium enterprises (SMEs). It represents a fundamental opportunity especially for those SMEs operating in the so‐called ‘green economy’ sectors, in order to be competitive in a National, European and International market with their sustainable products and services. Drawing upon a database of over 300 enterprises operating within the eight defined green sectors, this paper assesses the determinants and drawbacks of innovation. In particular, by using an econometrical approach, we tested the following propositions: (1) small dimension of enterprises is not an obstacle to their innovation capabilities; (2) the adoption of an internationalisation strategy is an opportunity and a stimulus to innovation for SMEs; (3) cooperation with research centres, financial partners, trade association and public entities can help SMEs to overcome difficulties and help them to develop and offer innovative products and services, so to be competitive at an international level. The econometric analysis shows a positive impact of the variables ‘dimension’ and ‘level of internationalisation’ on innovation capabilities. In addition, cooperation with research centres and access to capital market are positively related with effective innovations.     

Segmenting a business market for a professional service

This article uses benefit segmentation to analyze the structure of an industrial market for professional services— the market for CPA services among business firms. Data were collected from a random sample of U.S. business firms, stratified to include a broad cross section of the market for CPA services. Benefit segments were described by linking CPA selection criteria importance ratings with client firm characteristics such as business firm size. Examples of ways in which information about market structure can be used in marketing professional services are presented. The results provide evidence about the applicability of prior industrial marketing research and multilevel industrial market segmentation models to a professional services market.     

On regulations for 5G: Micro licensing for locally operated networks

Future 5G networks aim at providing new high-quality wireless services to meet stringent and case-specific needs of various vertical sectors beyond traditional mobile broadband offerings. 5G is expected to disrupt the mobile communication business ecosystem and open the market to drastically new sharing based network operational models. 5G technical features of network slicing and small cell deployments in higher carrier frequencies will lower the investment barrier for new entrants to deploy local radio access networks and offer vertical specific services in specific areas and allow them lease the remaining required infrastructure on demand from mobile network operators (MNO) or infrastructure vendors. To realize the full vision of 5G to benefit the society and promote competition, innovation and emergence of new services when the 5G end-to-end network spans across different stakeholders administrative domains, the existing regulations governing the mobile communication business ecosystem are being refined. This paper provides a tutorial overview on how 5G innovations impact mobile communications and reviews the regulatory elements relevant to 5G development for locally deployed networks. This paper expands the recent micro licensing model for local spectrum authorization in future 5G systems and provides guidelines for the development of the key micro licensing elements. This local micro licensing model can open the mobile market by allowing different stakeholders to deploy local small cell networks with locally issued spectrum licenses ensuring pre-defined quality guarantees for the vertical sectors’ case specific needs.

The Effects of a Job‐Creation Scheme: Evidence from Regional Variation in Program Capacities

In direct job‐creation schemes, unemployed individuals at risk of permanent labor market exclusion are offered temporary subsidized employment in public‐ or nonprofit‐sector firms in combination with skills training and sociopedagogical support. The main aim is to stabilize and qualify them for later re‐integration into the regular labor market. Exploiting exogenous regional variation in population‐group–specific program capacities, I find that, on average, such a program eases the transition out of unemployment but has no long‐term effect on regular employment.
