Construction contracts: law and management. 4th edition

This is a fully revised edition of the UK’s leading textbook on the law governing construction contracts and the management and administration of those contracts. Although the legal principles involved are an aspect of general contract law, the practical and commercial complexities of the construction industry have increasingly made this a specialist area. This new edition has been brought up to date with recent cases and developments in the law as it stands at March 2007. The basic approach of the book has been retained. Rather than provide a commentary on standard-form contracts, our approach is to introduce the general principles that underlie contracts in construction, illustrating them by reference to the most important standard forms currently in use. Some of the common standard-form contracts have been revised since the previous edition, and the text has been revised to take account of these changes. Practitioners (consultants, builders, clients and lawyers) will find this an extremely useful source of reference, providing in-depth explanations for all of the features found in contemporary construction contracts, with reasons. A unique feature of this book is the way that it brings together the relevant principles of law with the practical issues arising in construction cases. It is a key text for construction undergraduates and postgraduates as well as for those taking the RIBA Part III and CIOB Part II examinations.

March 4th, 1999 : the recognition-primed decision hypothesis

On March 4, 1999, the newly appointed President of the Brazilian Central Bank, Mr Armínio Fraga, raised interest rates to a staggering 45% per annum. The objective of that decision was to keep foreign investors assets in Brazil, and prevent the country from default. At the time, Brazil suffered frem an enormously intense crisis of confidence, and fears of such default were widespread. Mr Fraga was walking a very fine line when making that decision, for it could bring forth unintended effects: the market, already concerned about Brazil's sustainability, could perceive the increased rate as an irreversible step towards the abyss inevitable default. Economic theory postulates the rational actor model as the driving force behind economic decision-making. The objective of this thesis is to present and discuss the hypothesis that this particular decision, and by extension many others, are better explained threugh the recognition-primed decision mode!.

The impact of daycare attendance on math test scores for a cohort of 4th graders in Brazil

We estimate the impact of having attended center-based daycare institutions during early childhood on Math test scores at the 4th grade of elementary school. Because enrollment in daycare centers may depend on unobservable character-istics of the family and the child, we build and estimate a structural model of endogeneous choice of school to deal with the selectivity problem. We nd that attendance to daycare institutions is associated with a gain of approximately 0,04 standard deviation in Math test scores. This result is important to the extent our OLS results as well as most of the studies for Brazil nd no e¤ect associated to daycare attendance, suggesting selectivity may play a role on this finding.

DIFFERENT EFFECTS ON RAT ARTERIAL-PRESSURE AND HEART-RATE WHEN LOSARTAN IS INJECTED INTO THE 3RD-VENTRICLE OR 4TH-VENTRICLE

Cardiovascular responses to central losartan (LOS), a non-peptide angiotensin II (ANG II) receptor antagonist, were investigated by comparing the effects of LOS injection into the 3rd and 4th cerebral ventricles (3rdV, 4thV) on mean arterial pressure (MAP) and heart rate (HR). Adult male Holtzman rats were used (N = 6 animals per group). Average basal MAP and HR were 114 +/- 3 mmHg and 343 +/- 9 bpm (N = 23), respectively. LOS (50, 100 or 200 nmol/2 mu l) injected into the 3rdV induced presser (peak of 25 +/- 3 mmHg) and tachycardic (peak of 60 +/- 25 bpm) responses. LOS injected into the 4thV had no effect on MAP, but it induced bradycardia (peak of -35 +/- 15 bpm). KCl (200 nmol/2 mu l) injected into the 3rdV or into the 4thV had no effect on either MAP or HR compared to 0.9% saline injection. The results indicate that LOS injected into the third ventricle acts on forebrain structures to induce its presser and tachycardic effects and that bradycardia, likely dependent on hindbrain structures, is obtained when LOS is injected into the fourth ventricle.
