In many organisations a gap exists between IT management and emergency managemement. This paper illustrates how process improvement based on a maturity model can be used to help organisations to evaluate and improve the way they include IT dependability information in their emergency management. This paper presents the IDEM3 (IT Dependability in Emergency Management Maturity Model) process impr...

In Central Europe, full-tree (FT) harvesting is an increasingly common harvesting method in steep terrain harvesting due to the increased use of highly economical processor tower yarders. In conventional FT harvesting, nutrient removal from harvest sites is substantially higher than in cut-to-length (CTL) harvesting due to the extraction of nutrient-rich branches and foliage. One strategy to re...

We consider the harvesting of a population in a stochastic environment whose dynamics in the absence of harvesting are described by the logistic Verhulst-Pearl model. Using ergodic optimal control, we find the optimal harvesting strategy which maximizes the asymptotic yield of harvested individuals. To our knowledge, ergodic optimal control has not been used before to study harvesting strategie...

The maturity model in Information Systems (IS) research continues to grow in popularity, as an approach to evaluating and improving an organization's capabilities. In recent years, numerous maturity model contributions have been made; for example, in the areas of IT/business alignment, project management, and information life cycle management. However, concerns are expressed in the literature r...

Commercial harvesting is recognized to induce adaptive responses of life-history traits in fish populations, in particular by shifting the age and size at maturation through directional selection. In addition to such evolution of a target stock, the corresponding fishery itself may adapt, in terms of fishing policy, technological progress, fleet dynamics, and adaptive harvest. The aim of this s...

The Indo-Swiss collaboration in Biotechnology (ISCB) initiated in Phase IV a pigeon pea network considering the importance of pulses in the food and nutrition security of India. Pulses are grown on rainfed marginal lands with meagre nutrient and pest managements. Pigeon pea (Cajanus cajan L.) is the second largest pulse crop and is an important source of dietary proteins in India. India contrib...

The objective of this review is to compare the cost of coppice and longer rotation poplar harvesting technology. Harvesting technology for short rotation poplar has evolved over the years to address both coppice harvest and single-stem harvest systems. Two potential approaches for coppice harvesting are modified forage harvesters and modified mulcher-balers. Both of these systems effectively ha...

BACKGROUND Vein-graft harvesting with the use of endoscopy (endoscopic harvesting) is a technique that is widely used to reduce postoperative wound complications after coronary-artery bypass grafting (CABG), but the long-term effects on the rate of vein-graft failure and on clinical outcomes are unknown. METHODS We studied the outcomes in patients who underwent endoscopic harvesting (1753 pat...

A simulation study demonstrates how the nonlinear optical response of the Fenna-Matthews-Olson photosynthetic light-harvesting complex may be explored by a sequence of laser pulses specifically designed to probe the correlated dynamics of double excitations. Cross peaks in the 2D correlation plots of the spectra reveal projections of the double-exciton wavefunctions onto a basis of direct produ...

Multienzyme complexes and multifunctional proteins may confer a kinetic advantage by channelling reaction intermediates between consecutive enzymes and reducing the transient time for the establishment of steady states. A general means for quantitatively assessing the contribution of channelling to the reduction of pool size and transient time is presented. Restrictions to the kinetic advantage...
