This collection features three peer-reviewed literature reviews on
pesticide residues in agriculture. The first chapter outlines the
ways in which pesticide use can lead to increased pest problems,
such as pest resurgence and replacement, and the development of
pesticide resistance. The chapter examines current strategies for
mitigating the impacts of pesticides and refers to a detailed case
study on the diamondback moth (DBM) to demonstrate the practical
application of these strategies. The second chapter explores the
threat of pesticide poisoning to human health, either via
deliberate self-poisoning or via occupational exposure. It
discusses how best to monitor exposure to pesticides, as well as
how to minimize the human health risks that may arise as a result
of their use/exposure. The authors refer to a case study on
smallholder cotton farmers in the Republic of Benin to emphasise
the global pesticide poisoning crisis. The final chapter reviews
the environmental impacts of pesticide use in agriculture,
focussing on their contribution to global human and ecological
health issues. It provides an overview of how pesticides are
currently addressed in emission inventory and impact assessment,
and discusses the relevance of spatiotemporal variability in
modelling emissions and the toxicity and ecotoxicity impacts of
pesticides.
After the fall of Mubarak, Ben Ali, and Qadafi, the Arab World
faces multiple challenges especially with regard to political
transformation and governance. The diverse experiences highlighted
the vital role of the periphery and of seemingly marginal actors.
Although the political landscape of the region changed within
months, such developments were rooted in long-term transformations
of governance structures. This volume examines the questions of how
politics and the state in the MENA is shaped and challenged beyond
the center. It develops a novel perspective in Middle Eastern
studies center on micro-politics, assess its contribution to the
understanding of authoritarian rule and its transformation. It
closely links innovative (anthropologically inspired) analytical
concepts and ethnographic in-depth case studies from the Arab
world. Based on the debates on politics from below and dynamic
concepts of state, all the chapters focus on informal institutions,
non-elite actors, and the dynamic and contradictory relationship
between state and society.

Most natural populations intermittently experience extremely
stressful conditions. This book discusses how such conditions can
cause periods of intense selection, increasing both phenotypic and
genetic variation, and allowing organisms with novel
characteristics to be first generated and then established in the
population. The authors argue that stressful conditions can have a
major impact on the environment, backing up their arguments with
evidence from the fossil record. They suggest further that, as a
consequence, periods of stress must be taken into consideration
when long term conservation strategies are planned, particularly as
stressful conditions are becoming increasingly prevalent as a
result of human activities. This broad overview will be of great
interest to students and researchers in the field of evolutionary
biology, genetics, ecology, palaeontology and conservation biology.

The concept of innate immunity refers to the first-line host
defense that serves to limit infection in the early hours after
exposure to microorganisms. Recent data have highlighted
similarities between pathogen recognition, signaling pathways, and
effector mechanisms of innate immunity in Drosophila and mammals,
pointing to a common ancestry of these defenses. In addition to its
role in the early phase of defense, innate immunity in mammals
appears to playa key role in stimulating the subsequent clonal
response of adaptive immunity. Recent exciting information has
determined that the templates that are laid down in primitive life
forms, like flowering plants and insects, form the basic principles
of first line host defense that are conserved in mammalian systems.
The next frontier in the field is to understand the dynamic
adaptive changes that occur as a result of the inter play between
host defenses and infectious agents. One emerging theme is that
microorganisms are constantly seeking ways to co-opt host defenses.
On the other hand, host defense to infection is mediated by the
coordinate action of pattern recognition molecules and receptors
that, in mammals, are important and probably necessary antecedents
to the development of an adaptive immune response. Innate Immunity
aims to explore the intersection between host pathogen interactions
across an evolutionary spectrum that will inform our understanding
of the dynamic interplay between infectious agents and host defense
in man.
Interest in the way in which symbiotic bacteria can manipulate
reproduction in their invertebrate hosts has risen rapidly in
recent years. Discoveries have ranged from bacteria that can
determine the likelihood of their fruitfly hosts finding a partner
to mate with to bacteria infecting woodlice that can cause sex
changes in offspring. This unique book is the first comprehensive
and systematic review of the 'reproductive parasites'. Written by
leading experts in the field, it explores not only the intriguing
theoretical questions raised by the relationships between symbiotic
bacteria and their hosts, but also discusses a number of exciting
practical applications, such as potential for controlling the
reproduction of disease transmitting insects. Chapters on sex
reversal, sex-ratio distortion, and evolution are also included.
This timely and up-to-date volume will be important reading for
researchers and students in the fields of entomology, evolution,
ecology, genetics, and microbiology.
The earliest accounts of the Sino-Indian boundary dispute cast
India as the victim of Chinese betrayal and expansionism, but a
more favorable image of China vis-a-vis India has appeared since
the 1970s. Since then, China has been portrayed as the victim of
India's self-righteous intransigence, with the 1962 India-China war
occurring because China was provoked into practicing a justifiable
form of realpolitik. These two seemingly irreconcilable academic
schools of thought still exist. In this case study of India's
decision-making between the years of 1959 and 1963, the critical
first years of its border conflict with China, Steven A. Hoffmann
takes an important step in reconciling the conflicting views of the
crisis and of the ascribed reasons for the war that ensued in 1962.
Drawing on interviews with Indian officials, military officers, and
political leaders and on memoirs and other sources gathered during
concentrated research in India, England, and North America between
1983 and 1986, the author provides previously unknown material on
the perceptions and realities of Indian decision making. A model
for international crisis behavior, as proposed by Michael Brecher,
is used to help establish a balanced treatment of information and
offer insights into such questions as why India and China both
failed to understand one another's frontier psychologies and
strategies, and why the Nehru government did not succeed in
managing the conflict. This richly detailed and carefully
researched approach is invaluable in this time when India and China
are once again exploring ways to establish a solid relationship.
