Requirements Problems in Twelve Software Companies: An Empirical Analysis
(2002)A study of the problems experienced by twelve software companies in their requirements process is discussed. The aim of the work is to develop a more holistic understanding of the requirements process, so that companies ... -
Software Process Improvement Motivators : An Analysis using Multidimensional Scaling
(2002)In this paper we present an analysis of software practitioners' motivations for software process improvement (SPI). Our findings are based on an empirical study of SPI in 13 software companies where we conducted focus ... -
Motivators of Software Process Improvement : An Analysis of Practitioners' Views
(2002-05-15)We present empirical findings from our study of Software Process Improvement (SPI) motivators in 13 UK software companies. Our analysis aims to provide SPI managers with some insight into designing appropriate SPI ... -
The development and evaluation of a software prototype for computer adaptive testing
(2004)This paper presents ongoing research at the University of Hertfordshire on the use of computer-adaptive tests (CATs) in Higher Education. A software prototype based on Item Response Theory has been developed and is described ... -
A Computational Study on Circuit Size vs. Circuit Depth
(2006)We investigate the circuit complexity of classification problems in a machine learning setting, i.e. we attempt to find some rule that allows us to calculate a priori the number of threshold gates that is sufficient to ... -
Computer-assisted diagnosis of focal liver lesions on CT images
(2005)Rationale and Objective. The purpose of the study was to investigate a modified version of a so-called Perceptron algorithm in detecting focal liver lesions on CT scans. Materials and Methods. The modified Perceptron ... -
Spectropolarimetry of the 3-μm water-ice feature towards young stellar objects
(2002)We present spectropolarimetry of the 3-μm water-ice feature towards five young stellar objects embedded in molecular clouds, including the Becklin–Neugebauer object, with wavelength range and spectral resolution much ... -
A multi-epoch near-infrared study of the HH 7-11 protostellar outflow
(2003)We present near-infrared observations of the protostellar outflow HH 7–11 in the molecular hydrogen 1–0 S(1) and [Fe ii] 1.644-μm emission lines. Images at four epochs spread over 11 yr constrain the proper motions of the ... -
Infrared polarimetry of the southern massive star-forming region G333.6-0.2
(2001)We present 8-13μm spectropolarimetry, and 12- and 2-μm imaging polarimetry of the southern massive star-forming region G333.6−0.2. Spectro-polarimetry measurements show that the polarization observed towards the nebula ... -
Near-infrared imaging observations of the southern massive star-forming region G333.6-0.2
(2005)We present near-infrared broad-band JHK' images of the southern massive star-forming region G333.6−0.2. The slope of the K-luminosity function towards the region (0.24 ± 0.01) is considered to be equivalent to that expected ... -
Near-infrared high imaging polarimetry of the Red Rectangle
(2003)We have carried out KHL band high resolution imaging and H band imaging-polarimetry of the Red Rectangle nebula using CIAO and 36 element AO mounted on the 8.2m Subaru telescope. HK band images show a X-shape structure ... -
Magnetic fields in discs : what can be learned from infrared and mm polarimetry ?
(2002)Polarimetric imaging in the infrared and submm offers the possibility of identifying magnetic field configurations in astronomical objects. To test this conjecture a set of field geometries within internally heated discs ... -
Mid-infrared polarimetry and magnetic fields : an observing strategy
(2004)Linear polarimetry in the mid-infrared can be used to obtain magnetic field directions in astronomical sources. However, since the polarization can arise from emission and/or absorption from aligned grains, care is needed ... -
De-motivators Of Software Process Improvement : An Analysis Of Practitioners' Views
(2003)We present a study of software practitioners’ de-motivators for software process improvement (SPI). The aim of this study is to understand the nature of the issues that de-motivate software practitioners for SPI, so that ... -
Key success factors for implementing software process improvement : a maturity-based analysis
(2002)We report on a questionnaire survey of key success factors that impact software process improvement (SPI). We analysed responses to identify factors that have a major impact, or no impact, on implementing SPI. We found ... -
A quantitative and qualitative analysis of factors affecting software process improvement
(2003)Despite the growing body of research on software process improvement (SPI), there is still a great deal of variability in the success of SPI programmes. In this paper, we explore 26 factors that potentially affect SPI. We ... -
Privatisation of state-owned enterprises in Spain: redefining the political economy
(2001)Spain was at the forefront of a worldwide wave of privatisation in the 1990s. The process was driven by a mixture of pragmatism, belief in its economic benefits and a desire to be at the heart of Europe. It was lubricated ... -
Spanish foreign direct investment, transnationals and the redefinition of the Spanish business realm
(2001)Spanish outward direct investment grew substantially during the 1990s, transforming some Spanish businesses from national players to transnationals and adding a distinctive Latin American dimension to an essentially European ... -
The special operations executive in Norway 1940-1945: Policy and operations in the strategic and political context.
(De Montfort University, 2004)Between 1940 and 1945, the Special Operations Executive (SOE) carried out sabotage and organised resistance across occupied Europe. There have, however, only been a small number of scholarly studies of SOE’s activities, ... -
