Research area selection in academic departments

The paper treats the topic of long range planning in an applied research oriented university unit. The advantages and disadvantages of the relevance of planning in an academic frame are considered, and the need for a formal long-term consideration of the development of an academic research unit is presented. Endogenous and exogenous attributes of future desirable fields of research are determined. The desired attributes are translated into selection criteria and quantitative indicators. A compensatory type methodology for decision-making is applied in order to rank potential areas of research. An example of the application of the proposed methodology for selecting directions of development for an applied chemistry academic unit (Casali Institute of Applied Chemistry, The Hebrew University of Jerusalem) is presented and the results are discussed.

Adoption of e-government in three Latin American countries: Argentina,Brazil and Mexico

This paper discusses the adoption of e-government in three Latin American countries: Argentina, Brazil and Mexico. The study first presents a conceptual framework to examine the development and services of e-government, which is applied to assess its adoption in these leading Latin American economies. Study findings can shed some light on each nation as a model for successful development as well as the implementation of e-government in a non-industrialized, developing nation. The analysis also seeks to fill a void in the study of e-government in less developed nations, most of which are trying to catch up with their developed counterparts in this crucial aspect of digital governmental development.     

Abandon bad R&D projects with earlier marketing appraisals

The marketing concept in technology based firms is often applied too late in the product development cycle to prevent costly marketplace failure. This article stresses the need for the involvement of marketing much earlier in the development cycle and a framework for accomplishing this purpose is presented.     

University research and development of a microsatellite

Developing a microsatellite at a university is an effective means of training engineering students for an R&D career. Such a programme requires the adoption of many research and development processes from industry. This paper describes how tailored forms of systems engineering, project management and technology management were applied to develop a high technology product at a tertiary educational institution. This microsatellite development programme has produced students who are well prepared for the realities of engineering practice, and a research and development facility that earns research funding for the university.     

The Complementary Roles of Applied and Basic Research: A Knowledge‐Based Perspective*

While a great deal of scholastic effort has gone into discovering the multifaceted relationships between applied research initiatives and subsequent performance, relatively little empirical research addresses the performance impact from firm investments in basic research initiatives. Even less addresses the interactive roles of both types of research. The authors conceptualize and empirically evaluate the interactive relationship between applied and basic research initiatives and firm performance. Applied and basic research projects are knowledge creation activities in a product development domain, and both initiatives enhance the stored knowledge of a firm. Stored knowledge is the fuel that drives the product development engine. Applied research initiatives assimilate and exploit stored knowledge to develop new products. Basic research initiatives contribute to and enhance the stock of knowledge from which the applied initiatives are drawn. This expanded base of stored knowledge has positive ramifications for subsequent applied research initiatives. Results indicate that firms that engage in moderate or higher levels of applied research will see enhanced performance returns from additional investments in basic research. Conversely, firms that engage in relatively lower levels of applied research see no performance enhancement at any level of investment in basic research. Firms that rely on a flow of product innovations to provide a continued income stream must certainly invest in applied research initiatives. However, additional investment in directed basic research initiatives will augment future applied projects and could become the source of sustainable competitive advantage.

Optimal Valuation of Claims on Noisy Real Assets: Theory and an Application

A theory for valuing claims on noisy real assets is developed and applied. Central to the theory is determination of the dynamics for the best estimate of real asset value. The dynamics of the value estimate are shown to differ from the dynamics of the true asset value only in the arrival rate of information. The rate of information arrival in the value estimate can be faster or slower than information arrival in the true asset value, which can lead to unexpected outcomes in the valuation and exercise of options on noisy real assets. The theory we develop is illustrated through an application. An imperfectly competitive market for real estate development is examined, in which agents compete over the timing of lead investment. Information spillover and free–rider incentives are shown to cause significant delay in lead investment. Delay together with a competitive response once lead investment has occurred explain observed patterns of development in gentrified urban land markets and multistage development projects.     

Web-hosting market development status and its value as an indicator of a country's e-readiness

A country's e-readiness is essentially a measure of its business environment, a collection of factors that indicate how amenable a market is to Internet-based opportunities. An e-readiness assessment is based on several quantitative criteria, and among them the ICT market development indicators are considered as the most influential. Studies in the past have shown that the well-known indicators used for assessing the level of ICT market development in countries with emerging economy are not directly applicable. This paper provides another insight into the level of ICT market development in an emerging economy by analysing the adoption of web-hosting services in the country's business sector. The potential of such assessment to be as an indicator of the level of ICT development in a country is analysed. The underlying study of the web-hosting development was carried out as part of the European project WEBHOSTS. The approach applied and the findings were intended to be used as a decision support in locating and managing some of the risks in e-business development and potential investment by new entrants in a region that is accessing the developed part of Europe.     

金融发展效率对技术创新的门限特征

本文基于门限效应回归模型，分析我国自1995年第一季度至2014年第四季度的相关数据，以金融发展效率为门限变量，对金融发展效率与技术创新的关系进行了实证研究，结果表明金融发展与技术创新之间的关系表现出显著的门限特征，门限值为88.61%。当金融发展效率位于门限值以下时，金融发展效率的估计系数显著为负；当金融发展效率位于门限值之上时，金融发展效率的估计系数显著为正。这意味着在小于门限值时，金融发展效率抑制了技术创新；只有在大于门限值时，金融发展效率才能促进技术创新。促进技术创新需要提高金融发展效率，商业银行法修正案对存贷比监管指标的删除，必将进一步促进金融发展，推动技术 创新。
