The lack of design quality focus in construction: a case for examining suitable design processes
No full textA large number of projects in UK construction now involve contractor-led design and are thus very different from the traditional approach which formed the basis of the original Royal Institute of British Architects (RIBA) Outline Plan of Work. Such integrated and contractor-led approaches support the reform agenda of the late 1990s that was introduced to tackle process inefficiency. However, within the design professions there has been concern that this resulted in buildings that were designed-down to a cost rather than designed-up to a value. An attempt to address this resulted in the formation of the Commission for Architecture and Built Environment (CABE) in 1999 and the launch, in 2003, of the Design Quality Indicator (DQI) which measures how well a building satisfies stakeholders. This paper presents the early phases of doctoral research which will examine the impact of integrated design management approaches upon Design Quality
The relative dynamics of investment and the current account in the G-7 economies
No full textThis paper contributes to the empirics of the intertemporal approach to the current account. We use a cointegrated VAR framework to identify permanent and transitory components of country-specific and global shocks. Our approach allows us to empirically investigate the sensitivity to persistence implied by many forward-looking models and our results shed new light on the excess volatility of investment encountered by Glick and Rogoff (JME 1995). In G7 data, we find the relative current-account and investment response to be in line with the intertemporal approach
Long run recursive VAR models and QR decompositions
No full textLong-run recursive identification schemes are very popular in the structural VAR literature. This note suggests a two-step procedure based on QR decompositions as a solution algorithm for this type of identification problem. Our procedure will always deliver the exact solution and it is much easier to implement than a Newton-type iteration algorithm. It may therefore be very useful whenever quick and precise solutions of a long-run recursive schemes are required, e.g. in bootstrapping confidence intervals for impulse response
International macroeconomic fluctuations and the current account
No full textIntertemporal models of the current account generally assume that global shocks do not affect the current account. We use this assumption to identify global and country-specific shocks in a bivariate VAR. We test the quality of the identification using evidence from G7-data. In accordance with the theory, we observe a link between the global shock and a measure of the world real interest rate. We also find that long-term output growth is driven by global factors in most countries, that country-specific shocks are less persistent in smaller economies and generally less volatile than global shock
Grundtvigs embednedlæggelse 1826. En studie af H.J.H. Glædemark
No full textGlædemark: Grundtvig's Resignation from the Ministry in 1826. Reviewed by Steen Johansen. The historian H. J. H. Glædemark (now dead) has investigated from the standpoint of historical criticism the causes for Grundtvig’s unexpected resignation from the ministry in Copenhagen in May, 1826. All existing documents, letters, etc., are reproduced and analysed, and the author shows how difficult it is to get to the bottom of the matter, in spite of the abundant source material available. The greatest difficulty, however, lies in the understanding of Grundtvig’s character and plan of life, and here the author seems to fail to some extent, while also his knowledge of Grundtvig’s writings, especially of the information which Grundtvig himself gives about his resignation, leaves something to be desired. These faults give his investigations a somewhat one-sided character, though not diminishing the great usefulness of his researches
Johansen v. California State Automobile Association: Has California Adopted Strict Liability for an Insurer\u27s Failure to Settle
No full textUnder the case law culminating in Johansen v. California State Automobile Association, it is virtually impossible for an insurance carrier to reject a demand to settle within the policy limits and avoid liability for any excess judgment. The author explains this unannounced policy of strict liability and proposes a method of dealing with the problems created by such increased plaintiff leverage

Financial market crashes: Predicting bubbles using the Johansen-Ledoit-Sornette model
No full textIn this project we looked into financial markets. The goal of this project was to find out if a bubble is forming and when the most probable time of bursting would be. that is what we call the critical time. In order to do this we studied the work of Professor Didier Sornette, who is an expert in this field of mathematics. In this bachelor thesis we use the Johansen-Ledoit-Sornette (JLS) model and the Levenberg-Marquardt algorithm to predict the critical time of bubbles. By critical time we mean the most probable time of a bubble to burst, but not for certain: there is always a probability to attain the end of the bubble without bursting. \\We looked at the results Didier Sornette got in his work on Black Monday and tried to obtain the same results. Besides that we investigated the sensitivity of the JLS model and differences between variants of it, also when simulating our own data. In the end we looked at applying the model at real data. For the data we chose the Amsterdam Exchange Index and Bitcoin.Applied Mathematic
A screening assessment of the impact of sedimentological heterogeneity on CO2 migration and stratigraphic-baffling potential: Johansen and Cook formations, Northern Lights project, offshore Norway
No full textWe use a method combining experimental design, sketch-based reservoir modelling, and single-phase flow diagnostics to rapidly screen the impact of sedimentological heterogeneities that constitute baffles and barriers to CO2 migration in the Johansen and Cook formations at the Northern Lights CO2 storage site. The types and spatial organisation of sedimentological heterogeneities in the wave-dominated deltaic sandstones of the Johansen-Cook storage unit are constrained using core data from the 31/5-7 (Eos) well, previous interpretations of seismic data and regional well-log correlations, and outcrop and subsurface analogues. Delta planform geometry, clinoform dip, and facies-association interfingering extent along clinoforms control: (1) the distribution and connectivity of high-permeability medial and proximal delta-front sandstones, (2) effective horizontal and vertical permeability characteristics of the storage unit, and (3) pore volumes injected at breakthrough time (which approximates the efficiency of stratigraphic baffling). In addition, the lateral continuity of carbonate-cemented concretionary layers along transgressive surfaces impacts effective vertical permeability, and bioturbation intensity impacts effective horizontal and vertical permeability. The combined effects of these and other heterogeneities are also influential. Our results suggest that the baffling effect on CO2 migration and retention of sedimentological heterogeneity is an important precursor for later capillary, dissolution and mineral trapping
