Book Description

This book describes the method of data envelopment analysis that uses mathematical programming techniques to obtain measures of efficiency of individual forms from their observed input and output quantities. The method permits setting up realistic input-output targets for the firm's managers. A firm is considered to be technically inefficient when it fails to yield the maximum quantity of output producible from the input bundle it uses. Measurement of technical efficiency is important for performance evaluation and provides an objective basis for differential rewards in the context of production.

Book Description

At last-a proven system for developing the strategic innovations every company needs to compete and win
As everyone knows, today's unprecedented rate of business change demands new levels of strategic insight and adaptability. Reinventing Strategy is the first practical, systematic guide to creating an adaptive enterprise, showing how companies around the world are using the Strategic Learning approach to consistently out think, out maneuver, and out perform their competition. As Willie Pietersen explains, companies that aspire to long-term success must develop and implement strategy as part of a continuous four-step cycle-Learn, Focus, Align, Execute-and he offers dozens of provocative anecdotes and case studies, illustrating how to implement it at every level of an organization. Written with unusual clarity, frankness, and wit, Reinventing Strategy will change the way managers everywhere approach their greatest and most important challenge: the need to make strategy into a tool for ongoing corporate renewal.

Great book.......2005-02-13

I am an executive coach and a former management consultant, so that business strategy is one of my interests. I have found this book by chance browsing on Amazon.
This is a book I have loved. It is an outstanding synthesis of what is business strategy nowdays. The author wonderfully combines a solid theoretical framework (he is a professor at Columbia University now) with a very practical approach (he has been running a company as CEO beforehand and it definitely shows!). It is very well structured, down to earth, straightforward and still accurate and full of in-depth reflections. It is a rare demonstration (especially in business literature) that a book can be essential and to the point, without boring repetitions (typical in business books). It shows there is a real understanding and mastery of the subject matter.
A serious business book written with both the head and the heart. Thank you Mr Pietersen!

Willie Pietersen gives us great strategy AND great practice.......2002-05-05

Willie Pietersen's Reinventing Strategy contains the basics of strategy, i.e., how to win, how to align the organization behind the chosen strategies, how to be sure that superior insights drive the strategic process. If that alone were his contribution, this book would be a significant contribution to the strategy literature.

But Pietersen goes much further than that. He shows us how, exactly, to develop these strategies, how he himself developed such strategies and what he learned about leadership in the process.

This book is about strategy, implementation and one man's journey as a leader and life-long learner. The result is an immensely human business book. The singular voice of the author comes through with clarity and humility. I know of no other business book that combines theory and practice with such a strongly personal view. Pietersen talks about the value of developing a leadership credo in his book. This book is, in essence, his own credo from a lifetime of leading and learning.

Every Manager Should Read This Book.......2002-04-20

I am VP at a large consumer products company in Ohio and I found this book very insightful in the areas of creating strategy and leadership. I read a lot of business books and most are very slight in what they have to offer -- a few thoughts, old stories or worn out sayings. However, "Reinventing Strategy" is a real how-to-book and goes through running a successful business step-by-step. This book will definitely help my division be more profitable! In fact, I would love to go and take one of Prof. Pietersen's courses at Columbia University.

A survival guide for business.......2002-04-18

Willie Pietersen has managed to pull together what's really important to achieve breakthrough performance. He's done this by telling clearly and convincingly the lessons learned from his years as a chief executive, but explained them from his new role as a Professor of the Practice of Management at the Columbia Business School. I've had the personal pleasure of watching Pietersen in action with business leaders from around the world who have participated in Columbia's Executive Education programs. The overriding comment from these executives is "this guy makes sense and has shown we how to face up to the challenges to my business' survival." Reinventing Strategy: Using Strategic Learning to Create and Sustain Breakthrough Performance is the next best thing to the live program.

If you want to move from Strategy theory to action and have your business survive in the process, read this book.

Written in Willie Pietersens highly readable style,it has heft as well as humor, theory as well as practical examples. Oh that our Business School text books had been written thus!
I would recommend this book to anyone who sells anything.
Read the introductory chapters,grasp Pietersen's premise then go to any of the rich chapters. Concepts are clearly tagged, each making for a delicious informational meal that forces reflection.

Book Description

There is a growing sense of complacency about future food supplies in Asia and such complacency may be unwarranted. While rice productivity may increase due to technological innovations and policies promoting intensive rice production systems, this increase will be limited by a number of factors including withdrawal of land and labor from agriculture to other uses, increased competition for resources, and land degradation. Increased production is unlikely to match the increase in demand for rice because of population growth. This book provides a thorough assessment of the opportunities for increasing land productivity, including crop diversification, evaluates the successes and limitations of the Green Revolution for rice in Asia, and projects economic and technological trends forward over the next three decades.

Book Description

Reviewing the background and ethics of insect conservation as well as current threats to insect diversity, this book explains the reasoning behind, and the techniques used, to maintain and protect insect diversity. Insect conservation has recently become a significant component of conservation biology because insects make up such a large proportion of total species numbers and biomass.

Download Description

This groundbreaking book is a contemporary global synthesis of the rapidly developing and important field of insect conservation biology. Insects play important roles in terrestrial ecological processes and in maintaining the world as we know it. They present particular conservation challenges, especially as a quarter face extinction within the next few decades. This textbook addresses the ethical foundation of insect conservation, and asks why should we concern ourselves with conservation of a butterfly, beetle or bug? The success of insects and their diversity, which have survived glaciers, is now facing a more formidable obstacle: the meteoric impact of humans. After addressing threats, from invasive alien plants to climate change, the book explores ways insects and their habitats are prioritised, mapped, monitored and conserved. Landscape and species approaches are considered. This book is for undergraduates, postgraduates, researchers and managers in conservation biology or entomology, and the wider biological and environmental sciences.

Book Description

Interest in beetle conservation has long been evident, with many papers treating these abundant, ecologically important and popular insects. However, this issue of Journal of Insect Conservation is the first to be dedicated entirely to beetles, and it contains a number of papers, predominantly from outside Western Europe, to demonstrate the variety and scope of problems and conservation concerns that surround these insects. A short introductory perspective is followed by eight original contributions, in which beetles from many parts of the world are considered, and in which some major threats to their wellbeing are evaluated.

Book Description

This book is a paperback reprint of a previously published hardback. Insects are the major component of the world's biodiversity. By virtue of their vast numbers of both species and individuals, they are vital determinants of terrestrial ecological processes. Quantiatively, insects are important pointers for species-rich geographical areas. Qualitatively, they are also important, whether the subjects of conservation themselves or as tools for identifying biotic areas with high endemism. Insect Conservation Biology covers a wide range of topics from single species to landscape conservation, and from rare butterflies to the benefits-and-risks of biocontrol agents. The approach is both positive and realistic, with insects being discussed in the contexts of sustainable development, agroecology and monitoring environmental change. Ethical issues surrounding insects are also considered as well as clear ecommendations for the future. Conservation circles have given too little attention to the ecological significance of insects, while entomologists have been engaged mostly in controlling a tiny minority of species of insect pests. The realms of conservationists and entomologists are brought together in this ground-breaking book.

Description:
Surrogate taxa as indicators for biodiversity are widely used in conservation biology and ecology. However, available studies on the congruence of species diversity patterns in different taxa yielded inconsistent results, and correlations between taxa were few. To conserve or restore biodiversity in agricultural landscapes, knowledge on the response of different taxa to management regimes is crucial. In the present study we evaluated the congruence of diversity and similarity patterns among three insect taxa, i.e., bees, grasshoppers, and aculeate wasps, in a mosaic landscape in the Swiss Alps comprising extensively used grassland under different management regimes. In addition, we studied the influence of land use on the diversity and species composition of the three taxa. While species numbers were not significantly correlated between any pair of taxa, community similarities were positively correlated between bees and grasshoppers. The number of red-listed species was not correlated with the total number of species in bees and in grasshoppers. None of the investigated taxa reflected the species numbers or community similarities of the other taxa well enough to qualify as a general indicator for biodiversity. Remarkably, land use clearly influenced species composition, while its effect on species numbers was not significant. All management regimes of the grassland in the study area contribute substantially to the overall diversity of the three insect taxa. Conserving the variety of agricultural land uses will be the most promising step towards the conservation of biodiversity in the study area.

Description:
In NW Patagonia, forestry with rapid growing species is an expanding practice, especially in the semi-arid steppe. To provide data for managing forests for biodiversity, we studied the impact of forestry on the native ant assemblages. We sampled ants using pitfall traps in a wide geographical area, including steppe sites and pine plantations, both dense (forest cover 87% in average) and sparse (forest cover 52% in average) designs. We measured and analyzed ant abundance, species richness and species composition as response variables. Through our results, we show that ants are highly sensitive to pine tree forests. Ant abundance within plantations is lower and species composition significantly impoverished. However, the more open plantations sustained ant assemblages which resemble those of the native steppe samples. This is probably because the open forests allow for native under-story vegetation to grow as in the natural steppe sites. We suggest that tree presence in an otherwise shrub and grass dominated area is responsible for the changes in the ant assemblages. We also note that the presence of native vegetation cover predicts ant assemblage composition in these arid zones. From an applied point of view, our findings suggest that a more open plantation design will be accompanied by higher ant abundances and species richness, which in turn may bring about consequences for sustainable forest management in the area.

Description:
This paper reviews the effects that windstorm-induced drastic changes (micro-climate, soil, vegetation, and ground structural heterogeneity) have on forest insect communities. In the current context of shady and CWD-deprived managed forests, windthrow gaps act as regional biodiversity hotspots by maintaining habitat continuity in a mosaic landscape, and by facilitating the breeding and population growth of clearing specialists and saproxylic species. Windthrow gaps are dead-wood islands where forest protection and habitat conservation goals may stand against each other. Besides the quantitative effect of dead wood on bark beetle outbreaks and saproxylic diversity, the latter is favoured by key dead-wood micro-habitats such as large logs, snags and sun-exposed coarse woody debris. The role of natural enemies and sanitation operations in regulating pest outbreaks is discussed. Heterogeneous openings provide many micro-habitats favouring flower-visiting insects, phytophages on saplings, on fallen tree crowns, and on diverse understory flora, as well as ground insects on specific micro-sites.
