In this paper, we propose an alternative approach to array interpolation for the sectorized array processing of a uniform circular array. While other approaches do not fully consider the influence of out-of-sector signals on the in-sector response, our approach explicitly addresses this issue. By controlling the out-of-sector response, our interpolated array demonstrates a significantly improved a

The paper seeks to explore critically specific issues relating to IS, process and organizational change. The authors suggest that IS development should be regarded as a particular case of organisational change – an emergent consequence of individual and organisational learning processes. Empowerment of individuals to express their values, goals and preferences within the political and social conte

The environmental footprint of IT products are significant and, in spite of manufacturing and product design improvements, growing consumption of electronics results in increasing absolute environmental impact. Computers have short technological lifespan and a lot of the in-build performance, although necessary, remains idling for most of the time. Today, most of computers used in non-residential

The present study examined whether socio-motivational effects from working with a Teachable Agent (TA) might transfer from the formative learning phase to a summative test situation. Forty-nine students (9-10 years old) performed a digital pretest of math skills, then played a TA-based educational math game in school over a period of eight weeks. Thereafter, the students were divided into two grou

The paper examines and illustrates different trends in relation to historical energy use-related intensities and corresponding CO2 emission trends. The methodology encompasses a decomposition quantitative approach for estimating decoupling trends to energy use and economic and demographic parameters driving CO2 emission levels. The analysis covers both global and regional trends for the period 197

The research history and conditions in experimental archaeology up until today show a heavy emphasis on technological studies within a hypothetical-deductive theoretical paradigm. How is it possible to enhance the conditions for experimental archaeology so that it can also develop as a humanistic area of research, more closely related to existential perspectives of human life? We argue for the int

This book chapter discusses the reactions within a few Christian churches, Judaism and Islam to a number of recent biotechnological interventions: assisted reproduction, embryonic stem cells, genetic intervention, cloning, and organ transplantation.

This article examines the diffusion of the Balanced Scorecard (BSC) in Swedish municipalities. The point of departure in the article is that there is a gap in our understanding concerning the diffusion of new management tools. Over the last decade, research has largely been based on empirical evidence regarding early adopters. Furthermore, these studies have largely been based on case study eviden

Two experiments were carried out in order to learn more about the relation between the various acoustic cues to speaker age. The first included listening tests with resynthesized stimuli, and the second comprised automatic estimation of age using the CART (Classification And Regression Trees) technique. In the first experiment, results indicate that human listeners seem to rely more on spectral cu

Clopidogrel is an important and widely used antiplatelet drug; only the (S)-isomer is the active biological enantiomer. The industrial production of the active enantiomer involves resolution of the racemic compound using stoichiometric amounts of L-camphor sulphonic acid and crystallization in a process using large amounts of solvent. In the present study, the possibility of enzyme catalysed kinet

The existence of consistent individual differences in behaviour ('animal personality') has been well documented in recent years. However, how such individual variation in behaviour is maintained over evolutionary time is an ongoing conundrum. A well-studied axis of animal personality is individual variation along a bold-shy continuum, where individuals differ consistently in their propensity to ta
