Machine Control – A Design and Technology Discipline in Israel's Senior High Schools

This paper presents a concept of the Machine Control discipline developed through the past decade as part of the technological education reform in Israel. The discipline has been widely implemented in senior high schools as an optional matriculation subject. Principles, contents, experience, evaluation and challenges of the curriculum are discussed. Specific features of the discipline in rural, technological and general school environments are presented and illustrated by examples. Arguments in support of a cross-national comparison of specific technology programs are given. This revised version was published online in July 2006 with corrections to the Cover Date.     

Board composition,share ownership,and ‘underpricing’ of U.K. IPO firms

Using a sample of 251 IPOs in the United Kingdom, this paper examines interlinks between executive and nonexecutive characteristics, share ownership, and short‐term performance measured in terms of share offer ‘underpricing.’ It argues that executives' power and previous experience directly affect ex ante choice of nonexecutive directors and their ownership interests in the firm. These endogenously developed governance factors may be used by IPO teams strategically to reduce the extent of underpricing. However, there is a selective response of investors to different board characteristics and share ownership structure. Copyright © 2002 John Wiley & Sons, Ltd.     

Strategic Management of Technology

This article deals with technology as it relates to strategy design. It addresses the different views of reality between general managers and the organization's technologists. This becomes increasingly important in high levels of turbulence. It examines the role of the general management and technological myopia as major influencer in the decision-making process. The thrust of this article is on the assessment of gaps between management and technologists and methods to close them. The article completes with the role of management in managing and driving technological innovation while integrating technology strategy in the organization's strategy.     

Strategic and institutional effects on foreign IPO performance: Examining the impact of country of origin,corporate governance,and host country effects

Integrating signaling and institutional perspectives, we develop and test hypotheses relating institutions and corporate governance to foreign IPO success. Our investigation highlights the importance of three important drivers of foreign IPO success: home country legal institutions, corporate governance, and host capital market choice. This research demonstrates that board independence and country of origin effects are powerful signals. However, these factors do not have a universal impact on foreign IPO success. Instead, the value of home country institutions along with corporate governance signals are contingent upon the institutional environment in which international entrepreneurs choose to seek capital resources.     

What drives intermediation costs? A case of tennis betting market

We demonstrate that there is a considerable variation in bookmaker margins across matches, time and bookmakers. Our results imply that using match, tournament and players’ characteristics explains the variations in margins hence, they can be helpful in managing intermediation cost in a market of state-contingent assets: fixed-odds betting markets. We also provide evidence that bookmakers protect themselves by increasing odds on the favourite player, thus attracting more bettors to the favourite player, while deterring bettors from betting on the underdog by reducing the odds. By that process, bookmakers are possibly sacrificing a portion of their margin.     

RETRACTED ARTICLE: Prediction of economic growth by extreme learning approach based on science and technology transfer

The purpose of this research is to develop and apply the extreme learning machine (ELM) to forecast gross domestic product (GDP) growth rate. Economic growth may be developed on the basis on combination of different factors. In this investigation was analyzed the economic growth prediction based on the science and technology transfer. The main goal was to analyze the influence of number of granted European patents on the economic growth by field of technology. GDP was used as economic growth indicator. The ELM results are compared with genetic programming (GP) and artificial neural network (ANN). The reliability of the computational models were accessed based on simulation results and using several statistical indicators. Coefficient of determination for ELM method is 0.9841, for ANN method it is 0.7956 and for the GP method it is 0.7561. Based upon simulation results, it is demonstrated that ELM can be utilized effectively in applications of GDP forecasting.

     

DYNAMIC COHERENT ACCEPTABILITY INDICES AND THEIR APPLICATIONS TO FINANCE

In this paper, we present a theoretical framework for studying coherent acceptability indices (CAIs) in a dynamic setup. We study dynamic CAIs (DCAIs) and dynamic coherent risk measures (DCRMs), and we establish a duality between them. We derive a representation theorem for DCRMs in terms of a so‐called dynamically consistent sequence of sets of probability measures. Based on these results, we give a specific construction of DCAIs. We also provide examples of DCAIs, both abstract and also some that generalize selected classical financial measures of portfolio performance.

Simple axioms for countably additive subjective probability

This paper refines Savage’s theory of subjective probability for the case of countably additive beliefs. First, I replace his continuity axioms P6 and P7 with a simple modification of Arrow’s (1970) Monotone Continuity. Second, I relax Savage’s primitives: in my framework, the class of events need not be a σ-algebra, and acts need not have finite or bounded range. By varying the domains of acts and events, I obtain a unique extension of preference that parallels Caratheodory’s unique extension of probability measures. Aside from subjective expected utility, I characterize exponential time discounting in a setting with continuous time and an arbitrary consumption set.
