Plant parasitic nematodes are a main pest to crops. For ex am pie, the root-knot nematodes belonging to the genus Meloidogyne are worldwide in their distribution and attack almost every type of crop, causing considerable losses of yield and affecting quality of produce. The cyst nematodes within the genera Globodera and Heterodera constitute a major group of plant pathogens in many countries throughout the world, suppressing yields of potato, sugar beet, soybean and cereals. Several nematodes such as longidorids and trichodorids are implicated in the transmission of numerous plant viruses. Many others cause constraints to agricultural production either locally or on large areas. However, despite their economic importance (they account for worldwide crop reduction in excess of 10%), plant parasitic nematodes are still poorly understood, because most of them are obligate parasites of roots. Environmental concerns over the agricultural use of pesticides demand the development of alternative measures to control them. To achieve environmentally sound control, knowledge of the basic biology of nematodes must be expanded. Important research areas include understanding the molecular bases for pathogenicity, the molecular mechanisms of the host- parasite interactions and the genetic bases for population fluctuations. The workshop has, for the first time, brought together an international group of researchers using molecular approaches to study plant parasitic nematodes and their host responses.
This unique and fascinating study centers on the experiences of expatriate American women married to French men, residing in France, and struggling to maintain American language and culture in their French-American children. More than a narrow study, The Transplanted Woman aims at illustrating the general dynamics of family groups. Three main, overlapping fields of sociological inquiry are included: the family, bilingualism, and women's studies. This is a rare exploration into an international situation where the two languages and cultures considered are on an equal footing rather than in a dominant/dominated relation to one another. New emphasis is placed on the critical role of the father in supporting or undermining the authority of the mother in the transmission of the mother's language and culture. The bicultural family laboratory facilitates the understanding the choices which orient children's identities--in doing so revealing the distribution of power between the parental couple and demonstrating how parents compete for control of their children's allegiance and identities.
Presented in this document is a class of deterministic models describing the dynamics of two plant species whose characteristics are common to the majority of annual plants that have a seedbank. Formulated in terms of elementary dynamical systems, these models were developed in response to four major questions on the long-term outcomes of binary mixtures of plant species: Is ultimate coexistence possible? If not, which strain will win? Does the mixture approach an equilibrium? If so, how long does the mixture take to attain it? The book gives a detailed account of model construction, analysis and application to field data obtained from long-term trials. In the particular case study modelled, the species involved are two pastural strains whose dynamics have critical agricultural and economic implications for the areas in which they are found, including North America, the Mediterranean region and Australia. This study will be valuable to researchers and students in mathematical biology and to agronomists and botanists interested in population dynamics.
This book presents an overview of the scientific study of public management, gathering together some of the most authoritative experts in this area of study in Europe and the United States, writing specifically about their respective countries. These essays seek to present the national distinctiveness of the study of public management, in the context of specific state administration.
This book goes further than some previous books concerning public management by highlighting the underlying differences between Europe and the United States and amongst European countries, in relation to their particular political-administrative circumstances. The aim of this book is to establish a dialogue between Anglo-American and European approaches to public management, to encourage readers to see their own national ideas and practises in contrast to others and foster leaning by asking repeatedly 'compared to what?'
Kellie Jo Holly compiled "Domestic Violence Safety Plan - A comprehensive plan that will keep you safer whether you stay or leave" after reviewing several safety plans available from domestic violence programs across the United States. She found the plans to be useful, but no plan was comprehensive, so Kellie decided to create the safety plan she wished someone had given her. This is the second edition of that comprehensive safety plan and it includes planning for social network use after leaving the abusive relationship.This is a comprehensive domestic violence and abuse safety planning workbook. It is designed to keep you safer whether you choose to leave or remain in your abusive relationship or marriage. It is as important to protect yourself from the unseen abuses as well as the bruises you will most certainly receive if you choose to stay in your abusive relationship. Verbal, mental, and emotional abuse is domestic violence - you need a plan to keep your body and mind safe. If you already experienced physical assault, it is important to leave the relationship as soon as you can. However, leaving immediately and permanently may not always be possible. The goal of this safety plan is to keep you safer until you can, or decide to, permanently leave your abuser.Many people recommend this Domestic Violence Safety Plan to counselors, crisis line volunteers, nurses and triage workers, domestic violence groups and anyone who regularly talks with victims of domestic violence and abuse. Kellie wants victims of abuse to use this plan as the first step to healing from domestic violence and abuse.
